What is a rechargeable battery?

Answer 1

Yes.

Most ordinary "nonchargeable" batteries can very well be recharged a few times.

Most alkaline and lithium batteries can be recharged from 3 to 10 times.

Some lithium batteries even more.

I have actually not experimented with other "nonchargeable" batteries.

Problems:

The problem with recharging these types of batteries is that they are not designed to be recharged!

It should be done slowly over long time rather than very fast like most chargers today does.

You can not complain either if the batteries actually start leaking.

They might even "violently" crack open (Explode) if you try to charge them with a lot of current. This so called "explosion" is however not an actual explosion. Using the word "Explosion" causes un-needed fear. What actually may happen is that the pressure inside the battery increases during the charging process. the sealing of the battery may rupture and some of its content, acid or alkaline, may be forcefully sprayed out. This of which is harmfull to skin, espechially eyes. Slow recharging ensures low pressure and less chance of seal breaking.

My method and experiences.:

I recharge my Alkaline and Lithium AA Batteries over a time of approx 16 hours. My battery charger is adjustable and can deliver 25-200 mA. When recharging slowly with only 50mA, the batteries keep quite well and can be recharged a few times.

If recharging at 200 mA, they get warm (due to gas buildup and high pressure inside). This pressure causes batteries to crack open and leak. This mean that battery is forever dead.

As of not exactly knowing the capacity of a nonchargeable battery, it is a bit difficult to give a time frame for recharging. We can however somewhat count on a capacity comparable to similar rechargeable NiMh batteries. These batteries today are close to 2000 MAh. Easy math tells us that recharging such a battery at only 50 mAH takes time. Straight forward, 40 hours, but taken into consideration the loss factor of charging (approx 40%), it would take close to 60 hours to fully recharge.

If recharging at 100MAh this time would be halved to 30 Hours.

My experience though is that when I try to recharge a battery for that long, it will start to leak, almost no matter what. I never charge my alkaline batteries for more than approx 15-20 hours at 50-75 MAh. This will of course not give a full charge but the batteries can withstand it better than a full charge.

They last for ages afterwards in my mouse or keyboard.

Note:

My battery charger is full of corrosion due to battery-fluid from alkaline batteries.

This mainly because I forget the batteries in there for too long a time, or try to recharge too many times.

Answer 2

A battery that can be refilled with the energy it has. If it is in a phone, when you charge your phone, you are recharging the battery in your phone.

Answer 3

Well the advantages of rechargeable batteries are, They can be recharged, they save the world from global warming a little bit and they last a lot longer than regular batteries.

Answer 4

So that people can reuse them for more uses. Big Mac wrote this

Answer 5

It is a storage device or secondary cell that is used for recharging from time to time for our personal use. It is also an electrical battery.

Answer 6

NO they do not last longer
