According to the author says, many consumers go to electric vehicle battery place to see the battery brand, model, too many styles, there are the lead acids ,he lithium batteries, do not know the choice of what kind of battery? 

Then the lead-acid batteries and lithium batteries have what distinction? the author summed up the difference between several lithium battery and lead-acid battery,hoping to provide a reference for consumers: 

1, Durability: lead-acid batteries generally deep charging and discharge less than 400 times, memory, life in about two years. If you are using a maintenance free lead-acid batteries, need to pay attention to is the battery water loss less, use generally do not need to add distilled water. Lithium battery durability strong, consumption is slow,filling more than 500 times, and no memory, life in general in 4 - 5 years. On thedurability of the battery, good shock resistance, fully charged battery safety fixed state, with the amplitude of 4mm, 16.7Hz frequency vibration for 1 hours, no leakage,no cell expansion and rupture, the open circuit voltage is normal; overcharge resistance performance is good, 25 degrees Celsius, the state of the fully charged battery 0.1CA charge 48 hours, no leakage, no cell expansion and rupture, the open circuit voltage is normal, the capacity to maintain the rate of more than 95%; high current is good, fully charged battery 2CA discharge state of 5 minutes 5 seconds or10CA discharge, no conductive part of the fuse, without the appearance of deformation. I

2, Volume and Quality: General lead-acid battery weight 16-30 kilograms, large volume; lithium battery is in commonly 2.5, 3 kilograms, the volume is relatively small,so it is portable and convenient transportation. In terms of quality, both good and badis hard to define, consumers can according to their own needs, brand battery qualitygood to buy the regular manufacturers. I

3, Price, Warranty: currently on the market mainstream battery is 48 volts, ifreplacement, lead-acid batteries of about 450 yuan, the warranty period of 1 years;lithium battery is relatively expensive, need 1000 yuan or so, but the warranty period of two years. I

4, Travel Kilometer: 48V is the same cell, in a case of power, lead acid batteries andlithium battery electric vehicle can travel 30-40 km. Speed mainly depends on the motor size used. I

5, The battery capacity: the capacity of lead-acid batteries for the 20 or so; lithium battery capacity of 8 - 10. I

6, Environmental protection: issued "in 2012 the national lead storage battery industryaccess conditions", lead industry after the reorganization and integration, most manufacturers have adopted the internalization into non cadmium arsenic free green production, more environmental protection, more energy-efficient, only in the recoveryprocess, if improper methods may cause pollution; lithium batteries in the production,recovery, relative more green environmental protection.
