How To Choose The Battery Of Solar Lawn Lamp
Apr 28, 2017

Lithium-ion battery is the 20th century development of a new high-energy battery, it has a high energy density, in the same capacity, the weight of Ni-mh battery half, lead-acid battery 30%, the volume is lead-acid batteries and nickel-hydrogen battery 20. And the lithium-ion battery discharge platform is 3.7V, solar cell components of the charging voltage is 6V, compared to the lead-acid battery 12V discharge platform, battery pack charging voltage for 17V, can reduce the number of cell 2/3 of the scratch, reduce waste, improve the utilization of the battery sheet. Lithium ion battery cycle life is high, under normal conditions, its charging and discharging cycle can exceed 500 times. In sunny weather conditions, the battery components will continue to recharge batteries, and at night only consume the battery capacity of about 25%%, when the battery will be in a continuous floating state, can greatly prolong the life of the battery. Lithium-ion batteries do not contain materials such as cadmium, lead, mercury and other hazardous metal substances, non-chemical properties of the very lively metal lithium, can guarantee security, in line with the solar energy products green, environmental protection design concept.
