Only some of these can be recharged, which scientists call “secondary cells” – but for others, like most AA and AAA batteries, using the stored energy is a one-way street. Didi - Whether a battery is rechargeable or not depends on what the positive and negative electrodes are made of.
In general, only batteries that are specifically designed to be rechargeable can be charged up again after they’ve been used. This means that most AA, AAA, C, and D batteries cannot be recharged. The same goes for 9-volt batteries.
Batteries come in all shapes and sizes, but not all of them can be recharged. There are ways to bring your dead battery back to life. In general, only batteries that are specifically designed to be rechargeable can be charged up again after they’ve been used. This means that most AA, AAA, C, and D batteries cannot be recharged.
It has to do with the construction/design of the battery, non rechargeable ones are simpler to create, but they don’t have the pathway to reverse the reaction and recharge the batteries. Simply put, batteries are a chemical reaction that uses the flow of ions to create an electric current.
The most common AA and AAA batteries are called alkaline batteries, and these have zinc metal and manganese dioxide electrodes. When you use the battery, the zinc metal is eaten up and you form zinc oxide. Unfortunately this reaction is irreversible, which means that you cannot get the zinc metal back if you recharge the battery.
