If you decide to invest in rechargeable batteries, you’ll need to be sure you get the right charger for the batteries you purchase. Alkaline batteries can’t be recharged and, in fact, can even be dangerous and sometimes explosive.
Non-rechargeable batteries are typically called alkaline batteries, with zinc and manganese dioxide as electrodes and either potassium or sodium hydroxide as the electrolyte solution dividing the two. Rechargeable batteries have to be made of certain elements, like lithium, to allow for a safe recharging process. If you’re maintaining and using your rechargeable batteries properly, they can last you up to five to seven years.

Just like your smartphone battery life gets worse over time, rechargeable AA or AAA batteries will lose their ability to hold a full charge. Now, that’s not to say that you can buy a pack of rechargeable batteries and have it last you for life. This electron reversal process allows rechargeable batteries to be used again and again. Okay, So How Are Rechargeable Batteries Different From Standard Batteries? art_photo_s/ On the other hand, rechargeable batteries can use a charger to reverse electron flow so that the anode once again has a ton of electrons to give off and allow an electric current. When all the excess electrons from the anode have made their way to the cathode, the battery is dead and can no longer power any of your electronics. These positive and negative indicators represent a positive electrode and a negative electrode inside the battery, separated by an electrolyte solution that controls the electric current between both ends of the battery. If you grab a AA battery and take a close look at it, you’ll see a positive symbol (+) on one end and a negative symbol (-) on the other. Protons are positive particles, electrons are negative particles, and neutrons are neutral particles with no charge. Although it seems like protons, electrons, and neutrons were defined multiple times throughout grade school, here’s a refresher. Then, an atom is made up of particles called protons, neutrons, and electrons. Going back to very basic science, a battery, like everything else in life, is made up of atoms. If you already know how regular batteries work, you can skip ahead a little bit if not, check out this short explanation.
To understand how rechargeable batteries work, you first have to know how a standard (one-time use) battery works.
