How would you recharge rechargeable batteries?

Answer 1

One of the best ways to recharge batteries is to do so only until the battery is fully charged. Most battery chargers will have indicator lights that let you know the batteries are ready. Remove the batteries from the charger instead of leaving them on for an extended period of time after charging is complete. Overcharging batteries will decrease their life. Plan ahead for an optimum time to charge batteries, and set a timer to remind you to take them off the charger.
Some types of battery can be recharged (called secondary batteries). Others cannot (called primary batteries). You recharge a battery by connecting it to a power supply set to a higher voltage than the battery, usually through a current limiting resistor, connecting it to a special purpose power supply called a battery charger. To avoid damage to the battery, there are limits to how much current you can put into it, and this limit changes as the battery charges. These conditions are different for each type and size of battery. Consult the manufacturer of the battery if you need details. If you are actually asking "How is it that batteries can be recharged?" that is a different question. simply, batteries generate current by way of chemical reactions that generate free electrons that constitute the electric current output. Secondary batteries have a type of chemical reaction that can be driven in the opposite direction by applying an external current.

Answer 2

It depends what batteries they are.

Answer: though the answer is it depends on the type of rechargeable battery, some battery can be recharged by applying electricity in the reverse direction of the regular uncharging. Other may be recharged by physically removing and refilling the chemicals.

NOO that would be bad! Lets say its a 12 volt car battery, what you would do is have a voltage higher than that, 14.4 is the best for a car battery. Now lets talk about household batteries like AAA, AA, C, D. You would charge those at 1.5 or 1.6.

Answer 3

Plug the phone's charger you should of gotten with your phone in the specified hole on the phone (usually on the bottom or side of the cell phone.) Then plug the other end of the charger into a wall power outlet. Now wait a few hours and your phone will be fully charged.

Answer 4

Since there is claimed dangers in re-charging take your own risk to save a couple of dollars.

Watch batteries are typically 1.5 v. Take an alkaline 1.5 v AA battery and use a copper wire. Bent it in such a way as to hold the watch battery and the AA battery pinched together. The copper wire should be about three inches in length and have two 90 degree bends. The bends if placed properly will make the positive side of the battery connection. This system cannot overcharge your watch battery. Leave the connection for the day.

Answer 5

The rechargable batteries are easily available across the internet and on the high street. Once you have purchased them you will need to insert the batteries into the recharger and insert it into the power supply and allow to charge with the power on for the desired time for the for which ever battery you are charging, this is because different size batteries can take longer to charge.

you don't, you buy a new one XD
