Operating features:

  • When charging the battery, connect the charger connector to the battery first and then to the AC outlet;
  • After the battery is fully charged, turn off the AC power and then disconnect the battery.
  • If you first disconnect the battery pack from the charger during charging, especially when the charging current is high (red light), the charger can be easily damaged.
  • When the charger's LED indicator turns green, continue charging for 2-3 hours to balance the battery cells.
  • Please use the charger and battery in a dry place, avoid overheating and hypothermia.
  • Please try not to charge the battery immediately after the battery is depleted. Let it cool down.
  • Please do not charge the battery while it is being discharged. Otherwise, you risk damaging the battery.
  • Do not discharge the battery below the discharge voltage limit specified for the specific battery.
  • If you need to store the battery for a long time, leave the battery 40-50% charged.
  • Please do not use Li-Ion batteries in lead-acid UPS/Inverters without deep modification of the latter. Use a LiFePo4 battery and there will be little modification to the UPS/Inverters.
