Name: BYGD hundred surplus photoelectric 6810A 10A battery charger input voltage: AC 220V / 50HZ Input Current: 1A Operating temperature of about: 0 ℃ -40 ℃ Size: about 235 * 105 * 60mm (L * W * H) Power cord length: 50CM clip length: 50CM Weight: about 2KG The charger is suitable for 12V battery charging, simple, easy to use, safe, fast charging, and the battery has a good conservation role. * Intelligent charging: intelligent charging, suitable for home and go out to use. * Charging Mode: The three-stage charging mode, constant current charging, constant voltage charging, floating charge * The charger is only suitable for rated voltage of 12V rechargeable battery (12V 10AH-200AH battery) charger plug into the socket, clip line in the correct way a good clip battery charger charging display: Regular 2 under for the battery charge, the charger displays full: You can turn off the power, the battery may have been used 3, Chargers show reverse connection: that your clip line is negative wrong folder, replace the position 4 as soon as possible, the charger also has a short-circuit protection (please do not try) How to choose the lead-acid battery charger from the lead-acid battery birth, engineers have been exploring its fast charging reasonable . 1, the constant current charging: charging faster, but is likely to cause overcharge 2, constant voltage charging: Charging simple mode initial charge current, seriously affect the life of three multi-stage charging: a combination of constant current, constant voltage charging advantages can a faster way charging current selection: battery charging current is generally rated capacity is generally 0.1-0.2C (C is the battery capacity Capacity of shorthand). For example 12V 60AH battery charging current 6-12A within appropriate. Note: If the electrode reverse polarity indicator shows red, it indicates electrode backwards, must immediately wired the right way
