t is easy to recall and reuse. But Ni-MH battery has its downsides compared with Li-ion battery such as long charging time, heaviness, low capacity and memory effect. Although it suffers less from memory effect than Ni-Cd battery, it needs to be completely discharged before being charged, not only for laptop battery, but also for mobile phone battery.
Lithium-ion battery also has its own imperfections like high cost and less discharge/charge cycles. A Lithium-ion battery provides 400-600 discharge/charge cycles, 800 cycles by special improvement. Based on the calculation that the battery is charged once per day, the best lithium battery can end up its life after around over 2 years. While a Ni-MH battery provides more than 700 discharge/charge cycles, high quality Ni-MH can even provides 1200 cycles. With this comparison, Ni-MH battery's life is longer than lithium-ion battery. Therefore, we can say there are no perfect laptop batteries at present.
B. Production Origin
At the very beginning, Laptop battery mainly comes from Japan, Korea, Chinese mainland and Taiwan. Japan is the main place because most of laptop cells are produced by Japanese manufacturers such as Toshiba, Panasonic, Sanyo, NEC etc. Although there are many brands of laptop and many kinds of batteries, cells are from these Japanese brands. Manufacturing the cells has created a lot of profits for Japanese electronic companies. Most Chinese mainland and Taiwan's manufacturers produce with materials supplied by clients. And the cells used are made in Japan.
C. Weight, Figure and Capacity
Most of laptop batteries are quadrate. Only a small number of them for super-slim laptops are columniform. The weight of battery is dependent upon its material and the laptop the battery is used for. A NiMH battery that has the same capacity and figure with a Lithium battery will weigh twice the lithium battery.
The capacity is measured by mAh which has a direct relationship with battery run-time. Besides, th
