Battery Storage
High temperature or poor ventilation during storage and delivery will result high self-discharge rate.
Therefore, it is important to maintaining good ventilation and keeping away from fire, flame, water and
heat supply etc.
When storing the battery (not charging), disconnect from charger and load.
Store the batteries in a dry, clean and preferably cool location.
The batteries are supplied charged, however during storage it is advisable not to store batteries for
more than below without a supplementary recharge:
a)
Six months at 20 °C
b)
Three months at 30 °C
c)
Six weeks at 40 °C
d)
Three weeks at 50 °C
A supplementary charge is required to maintain the batteries stored for some period over advised time
limit from above. For detailed charging procedures, please refer to section 6.1 Supplementary Charge.
Failure to observe charging conditions may result in greatly reduced capacity and service life.

Battery System Installation Considerations:
No fire, flame or heat supply should be near the battery;
Avoid installation near heat supply or in direct sunlight;
Avoid operating in humid / damp locations;
Do not operate in sealed enclosed or without ventilation.
