How do you know if a AA battery is rechargeable?
(For example) AA batteries are available as rechargeable and non-rechargeable variants. As they are of identical construction, you have to read the tiny text on the battery to find out if they are rechargeable or not. Many producers do a great job in making it hard to find this information.
Can rechargeable AA batteries be used in any device?
You can use rechargeable batteries in absolutely any device where you would normally use an alkaline battery, unless stated otherwise by the device manufacturer. There are no interference implications using rechargeable battery brands that are different to the device brand.
Is it worth buying rechargeable AA batteries?
Single-use alkaline batteries are cheaper up front, but you might consider investing in a good set of AA rechargeable batteries instead. They'll provide years of service in toys, flashlights, and TV remote controls and save you a lot of money in the long run.
Why can't regular AA batteries be recharged?
Can alkaline batteries be recharged? Only batteries that are specifically labeled "rechargeable" should be recharged. Any attempt to recharge a non-rechargeable battery could result in rupture or leakage.

What is the lifespan of a rechargeable AA battery?
Rechargeable batteries have higher initial costs than their primary counterparts. Another important disadvantage is their self-discharge.
How many years do rechargeable AA batteries last?
Each charge cycle degrades the electrodes just a little bit more, meaning the battery loses performance over time, which is why even rechargeable batteries don't keep on working forever.
Are rechargeable batteries worth it?
Mostly Because cell voltages are not compatible. AA and AAA one use batteries are made with 1.5 volt cells that actually are 1.5 to 1.0 during their useful life. AA and AAA rechargeable cells are made with 1.2 volt cells that are pretty much constant between but can be 1.4 volts at the start and 1.0 volts at the end.

If your battery is sulfated, which results in low power and difficulty in recharging to full capacity, it can sometimes be recovered using proper pulse charging techniques. Wehmeyer warns, however, that there are an infinite variety of pulse charging techniques used by a wide variety of equipment sold for this purpose.
Why are there no rechargeable lithium AA batteries?
Rechargeable batteries are either dead entirely or partially alive. Depends if the electrolyte in them is not damaged/leaked for some reason, they should work pretty fine by recharging them. Sometimes due to deep discharge, you might need to recharge them a bit more then the usual charging time but that's about it.
