Product Highlights- Touch button lii-600 adopts the design of touch buttons, and it will send out a "beep" sound feedback when touched. responsive and easy to operate.
- Repair battery working principle: when the charger detects that the battery is losing power, it will allocate a small current to charge the battery/stop charging and observe the battery voltage change. the battery may be repaired multiple times. note. there is no guarantee that the battery will be repaired successfully.
- 3a fast charging the maximum charging current of lii-600 is 3000ma*4 slots. the charger will automatically allocate the charging current, if you are not satisfied, you can manually select the charging current.
- Test battery capacity press "mode" key to select "test" mode. it takes some time to test the battery capacity, please be patient.
- Temperature monitoring each tank has an independent temperature detection device. when the temperature reaches 65°c (149°f), the charger will lower the charging current by two gears. if the temperature still rises, the charging current will drop to the lowest gear. (current gear: 250ma, 500ma, 1000ma, 1500ma, 2000ma, 2500ma, 3000ma)
