How to repair the battery?
To the battery in accordance with the 0.1C current discharge, record the discharge time. Its discharge current multiplied by the number of hours of time, is the battery repair capacity. If the Chongqing battery capacity to reach the nominal capacity of more than 70%, the end of the repair.
Connect the positive and negative output of the repair instrument to the positive and negative pole of the battery, open the repair instrument, repair the battery. The first repair time should be no less than 48 hours.
Charge the battery at constant voltage. It is the beginning of the time, using 0.1C ~ 0.25C current charge, to 16.2V later, by reducing the current method to maintain the charging voltage, until the charge current drops to 0.03C when the stop charging.
Pry open the adhesive or heat-sealed battery cover, reveal the maintenance-free battery rubber exhaust valve, carefully remove the exhaust valve, save, observe the battery internal situation. Add 0.1% to 0.5% of the electrolyte to the battery, just to the battery above the flow of electrolyte. At the same time, check whether the black impurities, if there are obvious black turbid impurities, indicating that the battery plate has been significantly softened, the possibility of battery repair is relatively small. If there is no black muddy impurities, need to wait 4 hours later, the water fully into the battery. If it is only because the deactivation time is long and cause the battery capacity to decline, do not need to carry out this step operation, should go directly to step 3 pre-charge.
Maintain the battery before, first of all to clean up the battery appearance of the dust, remove the terminal above the stain and corrosion.
