You can recharge a AA battery if it is a rechargeable battery like the 12 volt battery in your vehicle. You can buy a rechargeable AA battery or one that is not rechargeable they just cost more money.
Wood will not accept any kind of electrical charge.
None, a car battery is lead-acid, not alkaline.
No, only rechargeable batteries can be recharged.
A car battery or an AA cell.
That depends on the battery. A car battery makes 12 volts. An AA cell battery makes 1.5 volts.
It depends on the brand of battery on how many times you can use a rechargebable battery. Some brands are better than others. I would guess it to be around 4.
To charge a battery, the charger voltage must be higher than the battery voltage. If a AA battery (or any other) has a normal voltage of 1.2V the charger voltage must be at least 1.2V. The type of voltage supply and its current capability is immaterial. No, the charging voltage have to be larger than the battery voltage, to charge 2 AA batteries, that is 3 volt if connected in series, so a voltage of at least 4 volt is needed
According to Energizer, they claim that their rechargeable AA batteries will hold their charge for up to 1 year. How long a battery lasts is also dependant on how much it is used.
It depends on which charger is being used.
The average battery is much more powerful than a battery made from a fruit. You would need many fruit to equal the charge put out by the average , say, AA battery.
A good AA battery has about 1.5 volts across it.
An AA battery will sink in water.
