A lithium battery, lithium batteries (lithium ion battery) features:
Laptop battery acer Laptop Battery
1. Have a high energy density, and high-capacity nickel-cadmium battery energy than 1.5 times its size, weight, 2 times the energy density;
2. High voltage, average voltage of 3.6v, a nickel-cadmium batteries, nickel metal hydride battery 3 times (nickel-cadmium, nickel metal hydride battery voltage is 1.2v);
3. With flat and high-voltage capacity;
4. Load characteristics, 2c discharge as possible;
5. A wide range of temperature -20 ~ 60 6. Good life of the charge and discharge, after discharge capacity of 500 at least 70%. TOSHIBA PA3465U-1BRS Battery Toshiba PA2487UR battery
Nickel-metal hydride batteries and lithium batteries differences:
First, the weight of the battery voltage of each cell point of view, are nickel-metal hydride and nickel cadmium 1.2v, while the lithium indeed 3.6v, lithium battery voltage is 3 times the other two. And the weight of the same type of lithium batteries and nickel cadmium batteries is almost equal, while heavier than nickel-metal hydride batteries. We can see that the weight of each different battery itself, but because of 3.6v lithium battery high voltage, in the case of the output voltage equal to the number of combinations of single battery can be reduced one third leaving after forming the battery weight and volume decrease.

Second, the memory effect of nickel-metal hydride batteries and nickel-cadmium batteries have the same memory effect. Therefore, the regular discharge of management is also required. This periodic discharge management is being handled fuzzy state, or even the knowledge of some of the incorrect conduct discharge (discharge or use a few times each time after the discharge is due to the company's vary) This cumbersome discharge management in the use of nickel-metal hydride batteries can not be avoided. In terms of relative lithium batteries because no memory effect, in the use of a very convenient and simple. It is completely without regard to the number of residual voltage, can be directly charged, the charging time will naturally be reduced.
