Mugen 1800mAh & 3600mAh Battery

Here's two batteries from Mugen Powers, a 1800mAh and 3600 mAh. From my understanding, The 1800mAh will work with the original stock battery cover. And of course the 3600mAh, has the bulkier build. Here's some links for those interested.

3600mAh is sick but im going to order the 1800 mAh i wish they made a 2000mAh normal looking battery with the stock cover.
Thx for the post!

Let us know how it works out. I'm curious if there are any heat issues associated with the larger-capacity battery.

I just bought the 1800mAh, but it will be shipped in 10 days and will take 10 more to arrive!

anybody got a 1800mah one yet? thinking of getting one but im not sure they are worth it, has anyone had a battery from these guys before?

Mugen is one of the best second party manufacturer for batteries! It's really quality, no Hongkong Crap.

Interesting, Ive always wondered about suposedly good aftermarket batteries. ....Mugen you say !

OEM batteries is the only option unless the battery is inbuilt. Why are people so gullible? The manufactures always uses the best cells for their phones as it is part of the features present, i.e. long talk/standby time.
I have a HD2 and bought two original batteries which were not from Ebay.

maybe its because the people who know they are no good are so patronising when they are saying such. Not everyone has knowledge of these things and not everyone has had experience of this before but thats no reason to talk down to them. Its logical that these batteries should be better, after all they are rated 400mah higher, if thats not the case then you cannot blame the person who buys it thinking it is.

After market batteries is not a new phenomena and people buying such batteries should have learned by others which have made those mistakes before. It does not matter if it says Mugen or whatever on the battery.
I bought a battery for SE P1 on Ebay for 3 GBP and the picture was showing the retail package. When I received the package it was a "Walkman" branded when P1 is a business phone. I filled a complaint and received my money back. I would never do it without PayPal covering the full amount. I knew it from the beginning, if it sounds to good to be true it is not.

no, but what about somebody doesnt know anything about battery tech, or somebody who simply bought their phone from and o2 shop and has never had experience of other people buying aftermarket batteries? how are they supposed to know?
i came into this thread asking questions because to me it seems a little too good too be true, i know very little about battery tech but i do know a fair bit about other areas. other people, even those on this site may not have the slightest clue other than 1800 is more than 1400 and to talk down to them because of this is very unfair.

Mugen makes horrible batteries and have a long history of such incidents such as the ones above.

£26+ for 400mAh more - seems a bit steep IMO.
Better to buy a second genuine BST-41 from SE - seen them for the same money all over the place:
For example: http://www.amazon.co.uk/EMARTBUY-GE...6?ie=UTF8&s=electronics&qid=1274285908&sr=1-6
and

So long as it arrives with SE logo and hologram on it, it's probably fine.

Not true. The P1 battery from Ebay did have a hologram but when comparing against the original battery there was a visible difference.

Mugen 3600 mAh battery
I got my 3600mAh battery on Friday and it works great! 5% drain an hour even with heavy useage. I can go the whole day without charging and still have 30% before I go to bed, beats the OG battery which I had to charge 2 times a day which sucked...

I'm personally a bit skeptical to 3rd party batteries, but I would like to have a 3600mha battery, the added thickness is not a problem. But as far as I know there only available battery from Sony is the stock 1500mha battery?

That's exactly how my original battery behaves... lol

Not for me.
My original 1500mAh battery was dead by 3.30-4pm after taking it off charge at 8.30am and that was with moderate use. Its been dead by 2pm before now.
Got my 1800mAh Mugen battery and i can take it off charge at 8.30am and have it still on 40% at 5pm after heavy use during my lunch hour.
It does work much better

Saw an eBay auction for the Mugen battery set up by "Mugen Battery".
Read the lower lines and they want to add 19% VAT after the sale is completed to all EU buyers by sending you a separate bill for the VAT (totally against eBay rules)!
What a bunch of shysters!

Do yourself a favor guys....

Stop the debacle and concern on whether or not the 1700mah, 1600mah 1500mah blah blah blah batteries are better than stock.. I have a LOT of experience with Li-Po and Li-Ion batteries (cell phones use Li-Ion technology) and I can tell you WITHOUT a doubt that all these knock off companies are full of SH^* trying to say there batteries are of a higher capacity than the stock battery while staying the same size. Although it is possible to cram more mah into the same size package with li-ion batteries it is VERY unlikely to be able to do so with the current technology out right now. Most of these companies rate their mah on a different scale and actually will pull the battery to a lower voltage to justify their claims when it dosent matter because cell phones have a safety feature that has to shut the phone down at the specified voltage to prevent fires. Yes fires, Li-Ion has a fire risk if it is depleted all the way, not the same risk as a Li-Po battery but a risk just the same. HTC has a separate department that deals specifically with batteries and I can assure you they know and use the most up-to-date batteries they can get their hands on for these devices. There is nothing for them to gain by using inferior batteries in our phone. Those that have purchased the seidio 1600 extended battery and claim to have a better life on the phone are under a placebo effect. If you are just purchasing this "Extended" battery as a spare than buy all means go right ahead but dont expect a miraculous two hours extra from it because it is of lesser quality than the stock battery. I have hundreds of dollars in battery testing and logging equipment and If you guys dont believe me i will run some tests on the stock vs. whichever battery you'd like me too and post the data for all to see, but Ive been down this road before with htc phones and have always come up with the same conclusion......The aftermarket "Extended" batteries actually have less mah's than their stock counterparts.
Of course Im not referring to the htc extended battery in this post, its obviously pushing more mah's with its monstrous size, lol.
....just sayin..

Oh' and to elaborate because Ive also read some concerns over the length of time for charging the thunderbolt (which does seem lengthy I will admit).
Since our phone has such a hard time time keeping up with a normal days use I believe what htc has done is given the battery a longer "saturation charge" for the battery to completely charge before it completes the charge cycle.
Li-ion batteries are charged on a 3 cycle charge system and stage two is what is considered the saturation cycle where the battery may sit at a relatively static voltage for a period of time to saturate the cells with current to top off the charge, some cell phones skimp on this step to give the phone a fast charge time which is termed "charge-and-run" and people assume the device has been adequately charged when it has not. For an adequate "FULL" charge without harming the battery or affecting battery life, typically li-ion batteries take approx. 3-4 hours.

So the 3 batteries I got for 12$ on ebay ARE paperweights?

I wouldnt go that far, I doubt any of the batteries are "paperweights" yet. Im just making the point that the claims of higher capacity are unfounded and the cheap knock-offs are of lesser quality. Also check where the batteries are made. Good quality Li-ion cells come from Japan.
One thing to note with the cheapies is the temp while charging or under heavy use. Get a temp monitor app and compare between the stock and your aftermarket batteries, they will probably run hotter. Unfortunately I dont have any other batteries to test for you guys other than the stock OEM battery otherwise I would. If I pick any up Ill cycle the stock vs. aftermarket and post the data log between the two.
Also I didnt mean the "fire" comment to worry anyone, Li-ion batteries have protection curcuit that will render the battery useless and unserviceable if the cell reaches a voltage of 2.70v or lower which is where the chemistry of li-ion becomes unstable.

I'll ship your one of the two 1700 when I get it if you wanna test it and post results. Just ask that you ship it back after your done.

ha, I bought the same ones you did.
I didn't expect them to be as good as the 1400 mAh battery that comes with the phone. I just wanted to have a spare battery available in case I'm traveling and watching movies or something (on a plane). Even though it says it's 1500 mAh, I expect them to be more around 1200 - 1400 mAh.

Check this website for some information on similar battery testing.

I used their results when I purchased the Seido 3500 for my Evo.

I've used Chinese batteries every chance I get. They do work. From an Eris to the Dinc. 3500mah. Never had a problem. Emails and games etc. I bought the extended battery along with the Tbolt. Just don't like the hump on the back. I'm on eBay every night waiting for the Chinese to strike with a extended battery. At least a Better extended back cover. For $10.99 free shipping ill wait 2 weeks for it. F%$% what u heard their cheap batteries work.

If you do I recommend you buy the 1500 MyTouch4G batteries from ChiChi's htcexpress or their store on amazon. They should be the same a the 1700 Thunderbolt batteries and $20 cheaper.

When I get around to ordering up the batteries Ill post a chart like that on a seperate thread for our phone. I have some pretty sophisticated logging equipment. It shows the temp, charge capacity, voltage, mah, cell balance and health in an easy to read graph.
Im not a battery nerd but I used to be into RC helicopters BIG time and when you have a $5000.00 helicopter that can kill someone its just normal practice to have the equipment to check your $800 batteries so they dont fail 80 feet in the air and blow up or decapitate someone, lol

Heres a video of one of my helicopters (Trex 700 electric) , this one uses two 6s 5000mah li-po batteries and each one costs over $300 and they only last 8 minutes before there dead The video isnt of me however, I need a video camera to post mine but the helicopter is identical for the most part.

(speaking from g1, nexus, and g2 experience only)
i've bought extended batteries for phones for less than $15 each all in the 2400 to 3600 mah range. they last 2-3 days with normal use. the oldest one is 3 years old (g1) and still performs like new.
iirc the seller was based in hongkong.
just saying.

the htc extended battery
personally of all the batteries i have tried this is by far the best one until sedio has an 3500mah then i will be getting that i think

Has anyone tried one of these cheapo ebay extended batteries?

Found this extended battery on ebay, was wondering if anyone on here has tried it, i know it looks hideous, but if you know your making a trip somewhere it could come in handy if it works the way its supposed to. Its cheap as hell too.

9 bucks... can't be too great,
but what can you lose? lol

Seems to me that if the larger aftermarket brands have trouble meeting the stated mAh rating on their batteries, what more of unbranded ones that goes for an even lower value?
I also still have very clear memory on exploding phones from third party batteries years ago

I bought a cheapo 3800mah and it lasts barely longer than my stock extended battery. I wish samsung made an official 3800mah version

Buy 2 stock batteries and solder them together. Works great.
3500 real mah. I didn't think the 2000 extended batteries would fit under the cover from the Hyperion I had here. I agree though, if I can solder it up in an evening, Samsung certainly could work up something.

hopefully more phones in the future will be like the razr and give us a factory extended battery closer to 3000mah.

Razr maxx when I had it for a week was sick! Hard use all day, charged every other day, seriously insane battery life. If that phone ever gets bootloader unlocked, I would be all over it again.

Have you done this solder thing? Any tips?

if you look at the battery in the phone you can see that there is some space at the top of each terminal, use this space to solder a fine piece of copper wire to a second battery. make sure to solder the batteries in parallel, positive to positive and negative to negative, to retain the same voltage.
i remember taking apart a so called 3500mah battery from ebay and they were just two cheap 1500mah batteries tapped together. Apparently in china 1500X2 is 3500.

Why does everyone want extended batteries? 99% of people have access to a power cord most of the day and just don't need it. Granted, I'm new to the phone, but I really hope I don't need to carry around a huge battery or two. Personally I'd rather charge it more often. Just my own opinion.

As long as you know that I don't see a problem. Spend $10, use it for 6 months, buy another one. Much better than spending $100 for a mugen.

Has anyone come across this before? Any reviews? Is this the Slim one?

I have never heard of this, but it looks amazing! Thank you. I'm gonna ask the seller. Seeming that the description claims it to be a Lithium Polymer battery it is very likely that it is normal sized. In the past I searched around and never found a lithium polymer battery for the Galaxy phones. It would be really nice if all phones had high capacity lithium polymer batteries.
My question is that something for the 19000 battery wise is the same size as all other Galaxy 1 variants correct?

Yes, you are right. After some more research @Wikipedia, LiPoly Batteries can have high capacity and can be used safely provided that you use the original chargers and not the cheap Chinese crap. BLE is not needed for them . I might buy one soon, If i do, will update this thread. Wish me luck.

Well ebay says he's got positive feedback so just keeping my fingers crossed.

Hi !
Any feedback about this battery ?
Did you received it in time ?
Is it really better than the 1500 or 1800mAh ?
Thank you

To good to be true I think
I'd also love a battery which claims what this one does at this price, but It seems to good to be true. A bit of Googling shows a review for this battery with 2/2 "average" reviews which show it did not perform as promised (but it did work). There are also some other review sites which say pretty much the same thing. (I'd love to post the URL but can't because I'm a noob. A search for B005O8S4V0 on amazon.co.uk will find this.
Also, I think that if this technology was legit Samsung would have shipped it with the unit itself !!
Pity, I was really hoping it would work. I hate it that all the aftermarket batteries I have purchased sucked compared to the original.
DG

Yep i've finally bought a 1800mAh PolaCell battery. It seemed more secured to me.
Maybe i'm wrong (I hope for those who bought it) but as you said the 2430mha chinese one is too cheap to be true.

Lithium Ion is different to Lithium Polymer, the one on the link is a Lithium Polymer
More Details here
Code:
http://jartiuch.wordpress.com/2007/11/01/nimh-or-li-ion-or-li-polymer-what-to-consider%E2%80%A6/
Basically, Lithium Polymer batteries can have the same size but higher capacity, so there is a good chance that the battery is real.
But again I haven't still bought it cause I am running on a tight budget, but I am planning to buy one when I am selling my phone so that I can buy an Galaxy S3.

That doesn't look like it could be a Li-Ion Polymer cell due to the rounded edge. Only a square edge or foil pack would mean it's a true prismatic cell which is the casing for Li-Ion Poly cells.
The 3.7V vs 3.6V already shows that most of these are using a technology better than just standard Li-Ion, so it wouldn't really be much of an improvement.
Different manufacturer use different materials for anode, cathode, and electrolyte and these Chinese companies use the cheapest ones. So you're either getting what you pay for or getting ripped off depending on how you look at the false advertising.

I heard this battery(same label/producer on other handsets) is very bad.

I think I grabbed the wrong one:
http://www.ebay.com/itm/28086765575...X:IT&_trksid=p3984.m1497.l2649#ht_3124wt_1163
It does look the same, but 2450. Interestingly it is made in Japan, not China. Here's the weight, plus the OEMs that I have for comparison:
32.3g OEM Captivate 1500mAh
34.3g Japan "Gold" 2450mAh
36.65g OEM Epic 1800mAh
So I was expecting it to come out around 1650mAh, but it gave me 1910 the first time. I'll use it for a few weeks and run another test. Not really sure what to expect though.
Edit: This battery is crap. 2nd run at 200mAh it failed at 4 hours, about 850mAh drained. Now it's hovering just over 3.5v, right over where the phone would shut down. Trying to get the rest out so I can cycle it again, but I think it will be getting a funeral tomorrow.

Been running the "2430mAh battery" for about a week now with Battery Monitor Widget. Estimated rating is ~1300 mAh. Not great, but still gets me through the day with light-moderate usage.
For $10 it was worth a shot. At least the battery isn't COMPLETE garbage. :S

I already have an 1800mah anker and it is working fine for around $10....I am getting an oem epic battery tomorrow hopefully and I just ordered this

Don't buy from that seller, seller1on1 did not ship a real mugen battery instead he shipped a cheap ass 3500mah chinese battery and door you can get on ebay for $8.

This has been the strangest battery. After the second cycle I got 2300mAh out of it, but the phone was randomly shutting off. It started behaving after that though.
From what I understand some of these no name batteries come from good manufacturers' fail bins. They sell them off cheap instead of dumping them in landfill. So if that is the case, it's kind of a gamble.

Cheap Gold Battery to Samsung i9000
Darkangels6sic6 said:
Oh wow. Thanks a lot. Much cheaper. Now I have to test. Just search for i9000 or Galaxy S 2450mah or 2430mah and find the correct one. This looks legit

Hello,
I buy my gold battery from the webstore pixinf.com they are cheaper than ebay and have fast shipping. The battery work more than 2 times than original one.
They give 2 years warranty and the battery is made on japan. :victory:
Regards

I just got the gold battery from eBay. 2430MAH along with the battery charger for charging the battery externally. It was about $8.50 and comes within a week. Just search i9000 gold battery. I'm pretty sure I've got it calibrated. With light use I get up to 13 hours so far and up to 10 hours approximately with heavier use. Amazing buy so far

[Q] Mugen Power 4600mAh battery for S3? Review?

I found this thread where G1_enthusiast reviewed Anker and Seidio batteries for S3, but I also found the 4600mAh battery from Mugen Power earlier than these, and ordered it.
All I head is that cheap batteries are made out of almost expired materials and work for like 200 charge cycles, which explains their price. The expensive ones like Mugen or Seidio work for 400-500 charges, which is better, but would be awesome if some one could review the 4600mAh one. I will post my results later when I receive it, but I don't have experience in doing such tests.
ADD INFO - Found video review on the web

reason why they are not popular is the price tag, i used to think their company is out of japan but in fact they are base out of hong kong (people tend to think china stufff are ****ty). so what make their battery better than anker or hyperion? having say that, i have own their battery before (G2 and SGS2) and they do make battery longer than stock. however i was not into crazy testing at the time. i will not pay 100 bucks for battery again, as long as anker is in bussiness.
seido is the only battery company that is base in texas...thats not to say their factory isnt in china either. they also make quality battery in the past

Well, as I head many times and experienced myself on older phones (I have a 3900mAh from Mugen for Nexus S that works for 1.5 years already) - industry standards cannot produce a good quality battery and sell it for 10$. Those batteries are usually made out of expired materials. The issue here is not just the capacity but the battery life cycle. Cheap batteries have confirmed to last for 100-200 charges, however batteries from Seidio or Mugen last for 400-600 charges, not to say about warranty and safety + NFC support.
Also, for me personally customer support and brand presence is more important than being cheap. If I can afford a phone that costs 800$, I surely can get a good quality battery for a 100$. I will get the battery soon, btw, and will let you know.

I wonder if the Mugen battery will work with the extended cases that are being offered. I got one from Hyperion that I like. Judging by pictures it looks like the Mugen extended door may be a little bigger or designed different.
If the Mugen would fit with the other extended doors and TPU cases I would buy it. I've had great luck with them,

If a cheap extended battery lasts for 200 charges and I charge it every 2 days, it's still going to last over a year. I expect to have a new phone by this time next year if not sooner. So what's the big deal?

Good point, I always try to get the best deal, but for some reason I stopped using ebay batteries long time ago after a couple of duds.

That is why you go for tested name brand but not super expensive. a mugen costs more than 5 times what a hyperion, qcell, etc. costs. but it is very unlikely they will last 5 times as many charges. there is nothing like a fresh battery!

Well, they're always out of stock...I guess they never back back-logs. Anyways, I've received my S3 battery and now I need to calibrate the phone according to their instruction. They say that it's necessary to charge 4-5 times for 8-12 hours before the phone recognizes the new capacity. Does anyone know why?

$100 for a battery! That's more than half what I payed for the phone itself

Why didn't you buy a stand with extra battery that recharges both at the same time and just carry the extra one with you? I did, 18 pounds in amazon.uk. That way there is no extra bulk, and it's much cheaper!

I tend to carry my phone around, that's why. I think that's the sole purpose of having an extended battery in the first place.

Who said anything about not carring it around? I also carry it around, along with the extra battery. At the end of the day i put them both charging.

Yup, when the other extended battery costs less than $30 bucks, why pay much more?

Thanks. Is this the official Samsung extended battery kit? Also, does the S3 fit in this dock when used with either an Incipio or SGP Neo Hybrid case?

This is not the official one, it's Chinese. But in a emergency the extra battery does the trick. The phone won't fit with the case, you have to take it off.
