Flooded Maintenance Free Battery Constant Voltage Charging: Use constant voltage 16.0V (maximum voltage＜16.2V, the liquid acid easier lose if over this voltage, the colour of magic eye will become black and lower life) charge with limited current 0.25 C20 for 12-24 hours or the charged current low 1%of the rated C20. For example : Rated capacity of 12V100AH battery is 100AH Limited Current :0.25C20=0.25X100=25A The low current shut off is: 1% X100=1A AGM Maintenance free Battery Constant Voltage Charging： Use constant voltage 14.1V-14.4V charge with limited current 0.25C20 for 12-24 hours or the charged current low 1%of the rated C20. For example : Rated capacity of 12V100AH battery is 100AH Limited Current :0.25C20=0.25X100=25A The low current shut off is: 1% X100=1A
1 .Please store battery at warehouse with well- ventilation, dry, cool and clean, keep the battery away from fire, flame, heat etc, and avoid humid and soggy place. 2. Check whether damage for the new battery, the appearance has no deformation, leakage, cracks and smudge, positive and negative terminals have obvious signs and clear. 3. Carefully check the quantity and type with the purchase order, and fill record (Type, Quantity, Date) after finishing inspection. 4. Check battery voltage or the status of electrolyte, if show “Need charge”, it should charge first before storage. 5.The temperature of storage should at -15～+40℃, the stored time of new battery mainly depend on temperature. Higher temperature, it will have higher self discharge of battery. Normally the stored time will decrease to half if the stored temperature increase 10℃.
It should follow the order as dismantle and install battery for car. Dismantle 1. Dismantle the “-” or “N” connection cable from the negative of battery. 2.Dismantle the “+”or“P”connection cable from the positive of battery. Installation 1.Connect the “+”or“P”connection cable to the positive of battery. 2. Connect the “-” or “N” connection cable to the negative of battery.
