The standard voltage for a rechargeable battery is 3.6 volts.Īdditionally, Yes, they are finally available. No, rechargeable batteries do not come in 1.5 volt sizes. The difference in voltage is due to the chemistry of the cell. When a cell is fully charged, it produces a higher voltage than when it is fully discharged. Each cell has a nominal voltage, which is the average voltage it produces. We hope that this article has helped to clear up any confusion that you may have had about 1.5 volt AA and AAA batteries! If you have any further questions, please feel free to contact us and we’ll be happy to help.Īdditionally, Batteries are made up of cells. So, while you can use a 1.2 volt AA or AAA rechargeable battery in place of a 1.5 volt AA or AAA battery, you cannot use a 1.5 volt AA or AAA battery in place of a 1.2 volt AA or AAA rechargeable battery. The 1.2 volt AA and AAA rechargeable batteries are nickel-metal hydride batteries, which means that they use a chemical reaction that is not compatible with the 1.5 volt AA and AAA batteries. The 1.5 volt AA and AAA batteries are alkaline batteries, which means that they use a different chemical reaction to create the electrical current than the 1.2 volt AA and AAA rechargeable batteries. The answer has to do with the chemistry of the different types of batteries. This is a question that we get asked a lot here at Battery Junction, and it’s a valid question! After all, there are 1.5 volt AA, AAA, C, and D batteries, so why not a 1.5 volt AA or AAA rechargeable battery? Why There Are No 1.5 V Rechargeable Batteries? In fact, an alkaline battery only benefits from 1.5 V voltage at the beginning of its discharge. There is no effect on the use of the equipment. 1.2 V batteries are typically used in smaller devices, such as watches, calculators, and remote control cars.Īn additional, You can use 1.2 V rechargeable batteries in devices that usually take 1.5 V throw away batteries. This is a great question! 1.2 V batteries will work in most devices that require 1.5 V batteries, but they will not last as long as 1.5 V batteries. Will 1.2 V Batteries Work Instead Of 1.5 V? The proper voltage for an AA/AAA NiCd/NiMh rechargeable battery is 1.25 Volts. Some are 1.5 volts and some are 1.2 volts.Īs well as that, The proper voltage for an AA/AAA alkaline battery is 1.5V.
