  • Remove your battery from a motorcycle. This is a safety precaution because the battery usually gets warm when charging.
  • Before you put the battery on a charge, check whether it has any physical damage or leakage. Otherwise, it may damage the charger.
  • Put the battery on a charge and keep on monitoring it until it is full. Note that when the battery is being charged, it emits hydrogen gas, which is extremely flammable.
