Rechargeable battery

There are many brands and types of rechargeable battery in the market. It is an option for those who want to save their cash on something else rather than buying batteries which last for only a few couple of hours. One of the most common rechargeable battery types is the NiCd rechargeable battery. It is a good choice for general purposes such as the tv remote control and the battery for clocks. If you want to use rechargeable batteries on a camera the NiMH and the Li-ion rechargeable battery is an option. NiCd, NiMH and the Li-ion are all alkaline rechargeable battery which provide higher mAH at lower e.m.f/voltage.

No matter what brand that you buy the most important thing to observe on the battery is its mAH. The higher it is the longer it will last until you recharge it again. As I mention in the earlier post the most suitable mAH of battery used in cameras or any other high energy consumption device must at least has a mAH of 1800 and higher. NiMH and Li-ion rechargeable batteries are the common ones used in digital cameras. NiMH and NiCd oftenly built as rechargeable AAs while the Li-ion is built as a built-in rechargeable battery.

The brands of rechargeable battery that I will recommend are GP, Energizer, Sony and Panasonic. The built in battery is not really built-in but it is custom made so that only the device will use that battery. Built-in battery often costly so make sure that you don't spoil it.
