When you purchase Ni-MH batteries, do not judge them by their capacity. For example, many people will choose 1200mAh battery when they need to make a choice between a 3.6V 1200mAh Ni-MH battery and a 7.2V 900mAh one because people think that higher capacity means that the battery can release more electricity in an hour. But it’s not true. In fact, the second battery is better than the first one because it has higher voltage. It has longer cycle life. That’s to say, in the condition of similar capacity, choose rechargeable Ni-MH battery of higher voltage to gain higher runtime.
The keypoint of Ni-MH battery is its cell. Now the relatively excellent cell is from Japan manufacturer, such as Sanyo, Toshiba, Panasonic, etc. Domestic cell R&D level is far behind from those companies, so imported rechargeable cell is the first choice if allowed. Surely, except for above Japan brand Ni-MH battery, Local TCL, Aigo, DEC offer good quality cell,as well. Their cheap sales price attracts lots of consumers.
An application experiment shows 1800mAh Ni-MH battery is the best choice. Currently 1800mAh Ni-MH battery owns the best cost performance in the market. As for brand, it depends on user’s consume level and requirement. Imported battery is the best choice, of course, local battery, like large battery would be good enough.
