BATTERY MODULE 24V, 12AH
16. RECOMMENDATIONS FOR A LONG BATTERY LIFE
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.

Store batteries fully charged
Do not store discharged batteries. Keep batteries fully charged!
Charge retention is important to get the longest battery life. Stored batteries which are not fully charged age faster
then charged batteries. Batteries which are not in use should be recharged at least once a year. The higher the
ambient temperature, the shorter the charging interval. At storage temperatures higher than 30°C, recharging should
be done at least every nine months.
