If the temperature is minus 10 degrees, it is only about 60% of that in summer. In order to avoid damage to the battery, it does not affect winter work.
Disassemble the battery and measure the voltage of each battery. If the voltage is too low, replace the battery with the same resistance and capacity voltage.
If the voltage is low, you can use a larger battery charger to charge and remove sulfur to repair it. After it is fully charged, use the discharge circuit to discharge it. After repeated several times, the battery can still be fully charged, that is, it is repaired.
