When it comes to rechargeable batteries, you may wonder why some are so much more expensive than others? Which one is the best? Well, there are several factors besides just the name brand to consider.
Nowadays, the best rechargeable batteries are the new hybrid Nickel-Metal Hydride (Ni-MH) cells. These batteries are very good for power-hungry devices like digital cameras, flashlights, remote controls and wireless game controllers. They come charged already and ready to use straight out of the pack. Unlike regular Ni-MH rechargeables, the new hybrid Ni-MH batteries hold their charge over many months. They also don’t lose their charge as quickly as standard Ni-MH rechargeables.

However, these hybrid Ni-MH rechargeables differ in storage capacity indicated by mAh (milli Amp hour) rating. The higher the rating the better it can handle constant high-drain equipments like digital cameras. You may find the batteries are rated at 2000mAh or 2100mAh. The mAh ratings play a role factor in the price difference. So be aware on this mAh rating when it comes to purchasing the best rechargeable batteries for your camera.
Before purchasing the batteries, you better know how many times you can charge them. Also it is important to know how long the charge last over time so you know if you need to use the batteries in a year you can rely on them. Below are some of the best rechargeable batteries to consider.
