The battery is first charged for general maintenance and then discharged at a 2-hour rate. During discharge, the voltage of the battery of fat tire electric bike is continuously measured, and the “backward” battery with insufficient discharge capacity is selected for treatment.
Add 1.050 of dilute sulfuric acid until the liquid electrolyte appears, and then continue charging for 12-15 hours. When charging, pay attention to the temperature of the battery not to exceed 500 c.
After charging, rest 0. 5-4 hours, redo 2 hours rate discharge.
During discharge, the value of a single grid voltage is measured, If the discharge time is not up to the standard or the single cell voltage reaches 1.6 v, the discharge time is much different from the normal single cell battery (the difference of 3 months, 6 months, 9 months, 10 minutes, 13 minutes or more) is more than 5 minutes, 8 minutes, 10 minutes and 13 minutes respectively. If the monthly difference is more than 15 minutes, you will need to repeat the above charge-discharge procedures. Until it meets the requirements.
