How to Prolong Rechargeable Battery Life?

If you have at home a remote controller, mp3 player, iPod, digital clock, digital camera, then you know what the difference between rechargeable and non-rechargeable batteries is. You probably used many different batteries, including rechargeables and non-rechargeables, Alkaline and Oxyride, Energizer and Duracell and so on.

In this article, I would like to present some tips on prolonging battery life. There are many rumors about prolonging battery life and some of them are true. You can purchase these batteries online via

First, you should know that the most common rechargeable batteries are NiMH (nickel-metal hydride cells) and NiCd (nickel-cadmium). NiCd acronym derived from nickel (Ni) and cadmium (Cd). If you have just bought NiMH or NiCd, they should be fully discharged and charged three times before using them.

Second, you should know NiMH and NiCd batteries self-discharge at a rate much faster than alkaline. It is calculated that at room temperature NiMH and NiCd will self-discharge at a rate of several percents per day, while the base will self-discharge at a rate of less than 2% per year.

Third, the rechargeable battery should be fully discharged and charged at least once every three months.

Fourth, it is always better to recharge your batteries slowly. Try to avoid using all rapid chargers, which charge the battery in a period between 15 and 30 minutes. Some of them are good, and some not so good.
