Temperature: 

The temperature has the most impact on the service life. The hotter the temperature, the earlier the wear-out phase 
of the battery begins. The wear-out results in a degradation of battery capacity. Place the battery module in a cool 
location, E.g. near the bottom of the control cabinet. Do not place the battery module near heat generating devices. 
Do not overcharge batteries!

Number of discharge cycles and depth of discharge: 

Do not discharge batteries more than necessary. Set buffer time limiter to the required buffer time. The number, as 
well as the depth of discharging cycles is limited. A replacement of the battery might be necessary earlier. 

When choosing the battery capacity, always try to get the next higher capacity than required. The depth of discharge 
reduces the service life of the battery and limits the number of cycles.
