Q. Do rechargeable batteries perform better than the disposable batteries?

Answer

Yes rechargeable batteries perform far better than disposable batteries. The simple reason being with rechargeable batteries you get peak performance at all times by just charging it. Also the modern battery chargers help rechargeable batteries to perform in their optimal level. Today battery chargers provide a refresh mode which drains rechargeable batteries before fully charging them again. This mode and function ensures that you always get the optimum performance and life from your batteries.
