The battery is full, the charger is empty, the indicator is off, or the light is green.
Close to full on the green light, small current constant voltage slow charge, fully full voltage to reach the limit voltage, do not charge.
If it is a lithium battery, there is a protection board, charge to the protection board to limit the voltage, the protection board will disconnect the charge to prevent overcharging. The charger has no output current.
Forklift charger, charger can be mainly divided into high frequency and power frequency two categories, high frequency, as the name suggests, is high frequency, can reach more than megabHz. Power frequency refers to low, medium frequency, generally domestic is 50HZ, foreign also has 60HZ, high frequency charger weight is generally relatively light, the price is slightly cheaper than the same type of power frequency charger, it does not have a transformer, the battery charging speed is relatively fast, power frequency charger weight is relatively heavy, with transformer, the cost is slightly higher price is also more expensive, Charge the battery for 8 to 10 hours to fully charge, and the charging speed is slower.
