6.1 Package:
There is product name, model, name of manufacturer, safety approval, serial number, User Manual and packing list in the package box.
 
6.2 Transportation:
Suit for transportation by truck,the products should be shielded by tent from sunshine, and loaded and unloaded carefully.
 
6.3 Storage:
Products should be stored in package box when it is not used. And warehouse temperature should be -40~70℃, and relative humidity is 5~95%. In the warehouse, there should not be harmful gas, inflammable, explosive products, and corrosive chemical products, and strong mechanical vibration, shock and strong magnetic field affection. The package box should be above ground at least 20cm height, and 50cm away from wall, thermal source, and vent. Under this requirement, product has 2years of storage period, and should be rechecked when over 2years.
 
7.     Reliability requirements & Warranty
MTBF(standard, environmental temperature, load requirement) ≥50K hours; testing condition: 25℃, full load, testing proved value. Warranty: 1 Years.
 
8. Charger wiring
10.1 A spark often on first connection of the charge to the battery terminals due to charging the internal output capacitors, this is normal and should not lead to undue concern, care should be taken to ensure the battery vent caps are closed and there are no flammable object in the vicinity of where the connection will be made
 
10.2 The charger has been calibrated to take account of the voltage drop in the DC output cables during operation, to prevent the possibility of over or under charging of the battery it is recommended the DC output cable are connected directly to the battery without modification. We are able to customize cable length and connections for volume customers with specific requirements.
