Technical data:

1,Shipment, delivery and storage
 

• Choose adequate means for shipment, delivery and handle, for the weight of a battery is heavy. Don’t roll and throw a battery pack.
• Avoiding of up sit- down.
• Be careful and not damage the terminals and valve plugs.
• Avoiding of short circuit a battery, since it’s fully charged.
• Store batteries at dry, clean, well-ventilated are. Batteries can be stored at 0~35°C for 6 months with recharge. Recharge the batteries once if storage period exceeds 6 months.
• Self-discharge during shipment and storage increase due to higher temperature and poor ventilation. Keep ventilation well and away from heat, flame and spark.
• Disconnecting batteries from a load and charging system when store the batteries.

2,Environment requirements
 

• Temperature range:Charge -10~+50°C,discharge -20~+50°C,storage -10~+40°C;
• Keep away from flame, heat, and spark.
• Keep away from sunlight and heat sources.
• Keep away from moisture, water.
• Not use a battery in a sealed enclosure.

3,Cautions before installing
 

• Requirement for batteries in series:Recommended total system voltage limit is no higher than 450 V.
• Requirement for batteries in parallel:Less than three strings in parallel is recommended.
• Multi-layer installation:Temperature difference between layer no greater than 3°C. 
• Clearance:Keep a clearance of 20mm at least between batteries for better heat dissipation.
• Ventilation:Well ventilation to keep hydrogen level below 0.8%.
• The favorite ambient temperature for long battery service life is 25±5°C, battery service life shorten half for every 10°C increase above 25°C.

4,Connecting of batteries
 

• Use isolated tools for the connecting.
• Connect batteries first, and then connect batteries to charger and load.
• Connect batteries in a string first, and then connect strings in parallel.

After connecting the cables with battery terminals, antirust such as Vaseline may be applied onto the junction points.
