Rechargeable batteries typically last longer than regular disposable batteries. When they lose their charge, the user simply plugs them into a charger for a period of time, and then they're ready to go again. Users will find that all types and brands of rechargeable batteries are different in their own ways.
Charging Time
The charging time on a rechargeable battery varies depending on the size. Some batteries charge in less than an hour, while others take 7 to 8 hours and possibly even overnight to recharge.
Temperature
The temperature at which the batteries are stored can actually enhance their life. Those stored at 100 degrees Fahrenheit lose up to 25 percent of their alkaline every year. Experts recommend keeping them at room temperature.
Best Performance
Rechargeable batteries work best after going through at least two charges. The batteries usually aren't fully charged when the individual buys them. Working through multiple charges gives the batteries the chance to even out and perform better.
Length
Rechargeable batteries last for at least 500 charges, and some varieties last up to 1,000 charges and more. Energizer guarantees that their rechargeable batteries will go through a minimum of 500 charges.
Rated Capacity
All rechargeable batteries have a rated capacity, which refers to how long it can last in a given situation such as taking digital pictures in a camera. Those with a higher rated capacity last longer.
