Intelligent Charger MT4000 MT4000 is a battery charger for 1.2v NI-MH/CD battery size: AA/AAA/A/SC/C and 3.7V Li-ion batteries: LIR26650, 22650, 26500, 18650, 17670, 18490, 17500, 17335, 16340(123A), 14500, 10440. Device MT4000 can charge and test batteries. The presence of back light LCD allows you to see a basic condition of a battery-voltage, process time, charge/ discharge current, mode, capacity and inner resistance.
Batteries should be removed from the device if it is not used for a long period of time to avoid damage through leaking. Leaking or damaged batteries might cause acid burns when in contact with skin, therefore use suitable protective gloves to handle corrupted batteries.
batteries ate still usable because they are not used for a long time and the internal leakage current emptied the battery by itself. To avoid this refusal by the charger, we suggest charging then with a normal 3v battery pack for a few seconds before insert into the charger.
