Temperature sensors should be mounted on the side of the battery case in the
middle of the bank. Mount the sensor so that it remains below the liquid level en-
suring an accurate reading of cell temperature. Half way down the case is general-
ly sufficient.
4.7 DELTA-Q CHARGING ALGORITHMS
The following link will take you to a US Battery Technical Service Bulletin regarding the
appropriate Delta-Q charging algorithms for each battery:

STORAGE
The following tips will help ensure that your batteries remain in good condition during
storage:
●
Fully charge batteries before placing in storage.
●
Store in a cool, dry location, protected from the elements.
●
Disconnect from equipment to eliminate potential parasitic loads that may dis-
charge the battery.
●
Batteries gradually self-discharge during storage. Monitor the specific gravity or
voltage every 4-6 weeks. Stored batteries should be given a boost charge when
they are at 80% state of charge (SOC) or less. Refer to Diagrams 9 and 10 for
specific gravity and voltage measurements for flooded/wet and AGM batteries re
-
spectively.
●
When batteries are taken out of storage, recharge before use.
●
If put on float voltage there is no need for periodic boost
