Sudden death of Tab 3 8.0 - Galaxy Tab 3 Q&A, Help & Troubleshooting

Hi,
I'll have rooted Galaxy tab 3 8.0 and since it's old it has been mostly only on light use with org rom for couple of years now. Org battery was going down, sudden shutdowns on heavy use and didn't have a juice anymore so I decided to order new battery. While I was waithing new battery to arrive I didn't use that tab and I forgot it to a freezing work car with power on so that tab/old battery froze and tab shutdown. Problem is that it won't charge or start anymore with new or with old battery. Not with any button combination or not with any cord or charger or pc, not with cold battery or not with warm battery. I also used multimeter to check that there is enough voltage in new batt to start. It just doesn't do anything. No light, no charging icon on screen, nothing. So is that galaxy tab just froze to death(was max - 10'c) or is there any other ways to try to recalibrate/reset power circuit on tab so it starts to understand again when there's battery or charging cable on? Now it's just stupid thing that doesn't seem to understant that there's battery inside and power cord plugged in.

What if it's not only the battery that got damaged? I bet there's more, that's why new battery does not help.

[P] my galaxy w wont charge

my galaxy w i8150 wont charge he recognaize that the chrger is connected but he wont charge the battery what should i do ?
and what part i need to replace to soulve this problem ?
please help me soon tnx !
usually,, the charging problem starts with the battery itself,,,
do check if your battery is bloated or not..
also check if yur charger is really working,,, maybe its the charger thats not working....
additional info,,(based on my experience)
fully drained battery usually takes a couple of minutes before it starts chaging itself,,
mine got fully drained while playing gta vice city,,
and when i immediately plug the chager,,, the phone shows a battery icon with a yellow warning in the lower left corner of the battery icon,, and not the usual green line that arises to show that its really charging,,
so i waited for at least 3minutes,,,,,
Charge with the phone off.
Or turn off your phone, remove battery, plug in charger, insert battery.
The second one is what I did when I panicked but its the procedure I did anyway.

Ace II not powering up after night.

Simply my ace II doesn't power up after night. No reaction to power button, no reaction to charger. Tried pulling off battery for half hour. Still no reaction. I think there was about 60-70% battery before i felt asleep (however, I can be wrong). Any ideas?
EDIT: Is it safe if I try putting charger wires in between battery and its connection pins, to check if it's case of usb socket? (I used this method on spica if my replacement battery discharged completly, spica couldn't charge replacement battery in bootloader).
I have checked would power-up on battery from my spica( I know it has another size, however just checked if it would work) Still no reaction.
Please, anyone any idea?
Have you tried to run in recovery mode ?
What rom do you have ? And what version of android ?
Put it on the charger for an hour. Usually this helps.

My Galaxy S2 SGH T989 does not charge with the new battery

Hi Folks,
I have bought a new original battery for my Galaxy S2 SGH T989 since my old battery is not holding the charge and discharges quickly. The new battery came with 40% charge. I have inserted the battery, turned off the phone and plugged into the charger whole night to make it ready for use. At morning, I am surprised to see the charge animation logo is showing as it is charging from 40%. I turned the phone on and saw the battery percentage as 41.
I tried to charge with the phone turned ON. And I noticed that it just charges for 2 to 3 seconds and then stops charging. The charging animation of the battery runs for 2 to 3 seconds and then stops. Have tried with different chargers, cables, power banks but it behaves the same. At times it charges for sometime like 15 to 20 mins and then stops. Somehow I managed to charge it to 90% but its really tiring to always keep an eye on it.
I am not facing this issue with my old battery. The old battery charges well with all the cables and chargers I have. I am not sure where could be the problem. Please help.

Battery full but won't turn on?

My Samsung Galaxy Tab 3 8" won't turn on after I didn't use it for around a month. I've done a lot of searching around but can't seem to find anything wrong with it and don't want to pay crazy money to get it fixed by Samsung.
I opened the back cover and tried all of the fixes like unplugging and holding certain buttons with no results. I got my multimeter and measured the B+ and B- on the battery which measured 4.25v, which should be full charge for a 3.7v battery, but it still won't turn on, even when plugged in it doesn't show up a charging symbol or any signs of life.
Is it completely dead or is there something I missed?
