How to look at the battery power size

　　The characteristics of common battery types:

　　1. Nickel-cadmium (NI-CD) battery

　　Nickel cadmium (NI-CD) voltage: 1.2V

　　The service life is: 500 times

　　The discharge temperature is: -20 degrees ~ 60 degrees

　　The charging temperature is: 0 degrees to 45 degrees

　　2. Nickel-hydride (NI-MH) rechargeable battery

　　Charging battery voltage: 1.2V

　　The service life is: 1000 times

　　The discharge temperature is: -10 degrees ~ 45 degrees

　　The charging temperature is: 10 degrees to 45 degrees

　　Remarks: At present, the maximum capacity of domestic 5 batteries is about 3000mAh.

　　3. Lithium ion (li-lon) charging battery

　　Charging battery voltage: 3.6V

　　The service life is: 500 times

　　The discharge temperature is: -20 degrees ~ 60 degrees

　　The charging temperature is: 0 degrees to 45 degrees

　　Remarks: The weight is 30%to 40%lighter than the nickel -hydride battery, and the capacity is more than 60%higher than that of nickel -metal hydride batteries. But it is not resistant to overcharging, if the charge will cause too much temperature and destroy the structure => explosion.

　　4. Lithium polymer battery

　　Voltage: 3.7V

　　The service life is: 500 times

　　The discharge temperature is: -20 degrees ~ 60 degrees

　　The charging temperature is: 0 degrees to 45 degrees

　　Remarks: The improved type of lithium battery, no battery solution, and the use of polymer electrolytes can be made into various shapes, which is stable than lithium batteries.
