12.8v lithium battery is the replacement of 12V lead-acid battery.
In 2020, the market share of lead-acid battery will exceed 63%, which is widely used in communication equipment, standby power supply and solar energy system.
However, due to its high maintenance cost, short battery life and great pollution to the environment, it is gradually replaced by lithium-ion batteries.
It is expected that the market share of lithium-ion batteries will be reversed to super lead-acid batteries in 2026.
The unit voltage of LiFePO4 battery is 3.2V, and the combined voltage is exactly the same as that of lead-acid battery.
Under the same volume, LiFePO4 battery has higher energy density and lighter weight.
For the time being, it is the best choice to replace lead-acid battery
