Safety Matters
l Please do not disassemble or modify by yourself, otherwise the sulphuric acid and lead inside the battery will cause damage to the human body and the environment.
l Never short circuit the positive and negative terminal, otherwise it will cause electric shock, fire or breakdown.
l Please securely fasten the screws of the terminal; the loosened screws can cause fire.
l Always disconnect the main power supply upon installation, otherwise it will cause electric shock
l Please ensure the battery not to get to oil, water or other chemicals, otherwise it will cause electric shock, fire, breakdown and etc.
l Please do not connect to the power source other than the nominal voltage, otherwise it will cause fire.
l Please do not use the battery directly as AC power, other wise it will cause fire and breakdown. Convertor like UPS is essential for AC purpose.
l Do not place the battery close to fire or heat to avoid explosion.
Please do not store or use the battery under the following conditions, otherwise it will cause breakdown, acid-leakage, electric-leakage etc.
l Places where temperature under -10℃ or beyond 50℃.
l Places where exposed directly to sun or rain.
l Places where there is moist or ice.
l Places where there is corrosive gas.
l Places where the moisture is high or dusty.
l Places where there is vibration or impact.
It should be stored under cool, dry and clean conditions.
Transportation, Storage & Maintenance
1. It should be handled with care as the battery is heavy shile the outside casing is easy to break, it should never be tossed as it would crack the casing, causing the highly corrosive sulphuric acid to leak and damaging the battery.
2. The battery is high density product, stacking up too high during transportation will damage the terminal at the bottom layer, the stack should not be higher than 5 layers.
3. The batteries in storage should be inspected once a month. If the terminal voltage is found lower than the nominal voltage, it should be recharged immediately, otherwise over-self-discharging may disable any recharging capability. In general, the recharge should be carried out once every 3 months.
4. The following inspection should be carried out in every season.
(1) To ensure the battery room to be clean, free of garbage and properly lit.
(2) To ensure all the safety equipments are in place and under normal function.
(3) To measure and record the air temperature in the battery room.
(4) To inspect the cleanness of the battery, signs of terminal damage or heating, and signs of any overheating damage of the outside casing or cover.
(5) To measure and record the system float charging voltage on the battery
(6) To measure and record the temperature of the control device of the battery.
(7) To measure and record the DC floating charging voltage of each unit.
(8) To measure and record the system balance voltage.
Battery Installation
A. Connection in Series: Only the batteries (or battery group) with similar practical capacity can be connected in series, battery group is equal to the total voltage of each battery. The capacity of the connected battery group is determined by the unit with the smallest practical capacity in the battery group.
1. Batteries with different nominal capacity should not be connected.
2. New and old batteries should not be connected.
3. Batteries provided by different manufacturers should not be connected.
4. Batteries with similar specification but different remaining capacity should not be connected; all batteries with different capacity should be recharged separately before connection.
5. Batteries newly installed must charged for fully 12 hours with current under 0.1C and pre-set voltage before use. After the capacity of different single battery is almost the same, the batteries can be tested and adjusted, which is very important for the service life and reliability of batteries.
B. Connection in parallel. Only the batteries (or battery group) with similar practical voltage can be connected in parallel, the voltage remains unchanged after connection and the total capacity is equal to the sum of all the batteries (battery group) connected.


Batteries with different nominal voltage should not be connected in parallel.
Charging, Discharging & Durability
A. Cycle Use:
1. If the equipment connected to the power source separates from the power source after battery fully charged and obtains power from batteries, cycle use method should be chosen under these circumstances.
2. There should be a limitation on the maximum voltage provided by the charging equipment during cycle charging(under temperature of 20℃): charging voltage of 2v battery is 2.35~2.45v; charging voltage of 6v battery is 7.05~7.35v;charging voltage of 12v battery is 14.4~14.7v. The maximum charging current should not be higher than the nominal capacity by 25%A.
3. Charging must be suspended immediately when battery is fully charged, otherwise the battery will be damage due to overcharging.
4. The battery should not be upside down during charging.
5. The cycle charging life depends on the depth of discharging, the deeper the battery discharged the shorter the battery will service, vice versa.
B. Floating Use:

1. If the equipment is always connected to the power source and is in a charging condition and when the outside power source ceases while power is supplied by the battery, the floating use method should be chosen under circumstances.
2. There should be a limitation on the maximum charging voltage provided by the floating charging equipment: each unit of floating charging voltage at 25℃ is 2.26~2.30v. The maximum charging current should not be higher than the nominal capacity by 25%A.
3. The floating charging life mainly depends on the floating charging voltage and the environment temperature, the higher is the floating charging voltage, and the shorter is the service life.
C. Discharging

When the terminal voltage is lower than the stipulated final voltage during the discharge or the multiple and intermittent discharge lasts until it reaches final voltage (no charging between 2 discharges), then it is considered as over-discharged. Over-discharged will cause damage to the battery and shorten the life of the battery. The values of the discharging current and final voltage are as follows:
