For 12V/24V,6-200Ah full intelligent automatic universal lithium battery pure copper charger Car Battery Charger power:250W Output voltage: 12/24V Input Voltage:AC-150V-250V Output current:12V-12A 2V-10A Capatity:6-200AH dimension:175*135*75mm Suitable for 12/24V (6-200) motorcycles, cars, trucks, dry batteries, water batteries, lead-acid maintenance-free batteries (including wet and dry) intelligent monitoring battery current, power and charging status 12V / 24V automatic switching, full charge automatically stop charging You can manually charge but also smart charging You can charge ordinary battery can also charge lithium battery Charging, repairing, battery maintenance, three-in-one Charge status analysis, battery status monitoring at any time Material:Metal + electronic components             For vehicle batteries, motorcycle batteries (small volume) which have been laid unused for a long time, the charging indicator may not go ON when charging (due to small current requirement resulted out of large internal resistance).In this situation, you can charge at the same time of huge power discharging (consumption).By this means you can judge if the charger is defective, and at the time the charging indicator will flash.(Normally, you can continue to floating charge for approximately 1 hour after the charging indicator turns Off until the fully charged. At this time, the battery is in excellent condition, you can use freely) (Though the indicator does not flash, the charger is in fact charging the battery in trickle floating mode. And, once large current need from the battery is detected by the charger, the indicator will go flashing). SPECIAL NOTICE: 1. Charging batteries of leakage for the first time shall be under manual monitoring. To avoid overcharging and bubbling, for the 1st and 2nd time, charging shall be stopped immediately once temperature rise is found of the battery. Temperature rise indicates that the battery is full before being charged or there is leakage which does not influence its usage. 2. When the charger is charging the battery, the cooling fan shall be working regularly. 3. An adjustable charger can adjust current size in accordance with battery needs for a better battery protection. For example, if the current is 30A before charging, you are advised to decrease to 25A. Similarly, if 25A, you are advised to decrease to 20A. The 20% spacing shall better protect your battery as well as your charger. If the battery is not needed urgently, you are advised to charge by 1/10, i.e. 10AH battery to 1A charging current. Charging modes: manual VS automatic Automatic charging mode: charge 12V and full voltage is 13.8V-14.3V.Manual charging mode: max voltage is 16V, and so on. Advantages: automatic charging mode In this mode, you can just connect mains supply and battery to start without manual interference needed; the charging current will adjust itself in accordance with battery needs and stop charging in an automatic mann
