There are two primary types of AA batteries: those that are intended for single use and those that are rechargeable. Rechargeables are becoming more popular because the demand for reusing batteries and conserving resources has grown in recent years. Learn to recognize the differences between these two types of AA batteries by reading on.
Single-Use Batteries
Single-use batteries have a single charge that cannot be restored. These batteries tend to perform better than rechargeable batteries, as they contain a full battery charge from the outset. However, once that charge has been depleted, they are virtually useless. Consider proper disposal techniques for batteries before throwing out single-use batteries.
Rechargeables
Rechargeable AA batteries begin with a full charge. Once that charge has been depleted, a battery charger can restore most of the charge to the battery. It is important to follow the instructions on the charger and batteries in order to obtain a complete charge. Failing to do so will limit the lifespan and charge capacity of the battery. Additionally, rechargeable batteries gradually lose their full charge capacity over time and repeat recharges. As a result, even rechargeable batteries must be replaced eventually.
