12.8V12Ah Lead Acid Battery Replacement OEM / ODM
For Solar Storage System
Standard charge
Charge the battery with Lithium ion battery special test cabinet,
supply 14.4V voltage, constant-current 0.2C(A) current until
current down to 0.02C(A)
Standard discharge
Discharge the battery at 0.2C(A) to 10.0V or battery cut off
voltage.
