Rechargeable batteries lose their effectiveness over time. You could try discharging the battery completely and then recharging. However it is likely you may need a new battery.
Yes, provided that there is still enough residual charge to power on the tablet device itself.
If you charge the battery and it is not working then there is something wrong with the battery. Batteries are not usually repairable.
Fully charge the battery and have it load tested at anyplace that sells batteries.
Regular batteries will power a solar light until they run out of power. But regular batteries can't be charged from the solar cells unless rechargeable batteries are used instead. There is also a bit of circuitry involved.
If you are relying on solar power, and have no connection to the supply system, you would have a problem. Same at night. The answer is to have a large battery (probably a lead-acid cell) which you charge up during sunny weather, and use the stored energy as required. The system would need to be designed to cope with this in the first place. If you were reliant on solar electricity because of no grid connection then the electricity produced by the solar panels would be stored in efficient solar batteries. The power is then supplied from the batteries, day and night, and also when it's cloudy. Of course, some power will still be produced when it's cloudy, supplying charge to the batteries.
The only way to stop the batteries charging on AC power if they need charging is to remove the batteries, if possible. Most tablets cannot do this. On an Apple iPad, plugging the USB cable in to a iPhone charger will show 'Not Charging' on the screen, since it cannot provide enough current to charge the iPad's larger batteries. This is not AC power, however, as it will still slowly drain the batteries if the iPad is used.
You will have a 12 Volt source with double the charge capacity.
Yes, but it will shorten the life of the battery. L-Ion batteries are rated by charges, IE: How many times you can charge them and still maintain a workable volt amp in the battery (chemical reaction).
Panasonic does not manufacture batteries for older cameras any longer, however that does not mean the batteries can not be found. Online retailers such as Amazon still carry old batteries from sellers who no longer need them.
no
The following is applicable to android tablets:If it's still on:Alternate trying to charge it with its USB charger on a laptop and its wall chargerSwitch it off and try the same as aboveIf it's offAgain, alternate trying to charge it with its USB charger and its wall chargerIf none of these work, then the problem might be with the device or the battery itself. It would be advisable to return it to the store where you bought it especially if its still within its warantee period or alternatively, your nearest cellphone/tablet repair shop.
