How have I cooked my battery?
Hi all, sorry to just join the forum and ask for help but needs must I'm afraid.
I've had my tablet for a little over 2 months now. It is a Verses 7 touchtab 16GB version. Now the battery life is appalling to be honest so today I decided I would solve this by buying a portable battery and fixing it to my tablet case to give me a few hours extra. The first one I tried was a 6000mAh battery from Maplins, now I didn't realize at the time but this could only power a device at 1 amp output which was half the amount my device needed, so I returned the item for a 10000mAh battery which could deliver at 2A, or 2000mA. I've had the tablet plugged in and have been using it for the better part of the day and just now while watching a video the portable battery decided to give up. The percentage on the device says it was at 82% but immediately as the portable battery gave out the device shut off, no shut down or warning battery low messages just boom, gone. I tried to power up the device and twice the logo flashed up then it shut off again. Now I find the tablet will boot up normally if it is plugged into the wall charger and the battery percentage appears to increase as it should but as soon as I unplug it, it turns off completely, now powering down etc. From what I can see the portable battery meets the needs of my tablet ideally, 5V, 2000mAh output so I can't understand how it has managed to destroy my battery, have I got my numbers mixed up? The tablet has not become hot or acted out throughout the entire time I've been using it which I would have assumed were signs it was not happy with its charging situation.
I'm not sure where to go from here, will I have to change the battery? And is this just a sign of a weak battery to start with and I can continue to use my portable battery on the new one of should I take it back to Maplins and just deal with terrible battery life which is after all better than none
Any advice or help on where to go next is greatly appreciated thanks guys and gals!
