1. Battery Operation
The performance and life of a battery will vary with application useage,
temperature and depth of discharge AGM batteries tend to deliver higher
than their rated capacity (up to 10-15% higher) for 30 cycles until they
are “broken in” and settle at their rated capacity.
1.1 Temperature effects on Battery Performance and life
Operating batteries above 80ºF (27ºC) will yield runtimes below the rated
capacity and operating batteries below 80ºF (27ºC)will yield runtimes below
the rated capacity. Cold temperatures can significantly reduce battery
capacity. See
Chart 1.
2. Battery Storage
AGM batteries have a much longer shelf life than wet lead-acid batteries .
With a self-discharge of only 1-3% per month, AGM batteries can be stored
for a year or longer without needing to be charged.
2.1 Battery Storage Procedure
1. Charge batteries before they are placed in storage.
2. Disconnect the batteries from the equipment and charger to eliminate any
parasitic loads.
3. Check the batteries based on conditions and schedule in Chart 4.

Although higher temperatures increse the battery capacity they also
accelerate corrosion and reduce overall battery life. For example, batteries
operating continuously at 100ºF (37.8ºC) could experience
as much as 25% reduction in life.

1.3 Depth of Discharge versus Battery Life
Battery cycle life will vary significantly depending on the depth of discharge.
The deeper the depth of distance the fewer cycles a battery will deliver.
Conversely, the shallower the depth of discharge the more cycles a battery
will deliver. See
Chart 3.

4. Check the open circuit voltage (OCV) of each battery in the set and if any
battery within the set is less than the values in Chart 5, recharge the
battery set.
5. If the charger has a maintenance mode select that mode to boost charge the
batteries. Otherwise run the normal charge cycle.
6. If the batteries are stored less than the time periods in Chart 4, they do
not need to be recharged prior to being put back into service.
TIP: Batteries CAN be safely stored on concrete floors without any negative
effects. Concrete floors DO NOT drain batteries.
2.2 Temperature effects on Self-Discharging
If the storage environment is hot, batteries will self-discharge faster than in a cold
environment. See
Chart 5.
