2.2 | BATTERY MAINTENANCE AGM BATTERIES
Battery cycle life will vary significantly depending on the depth of discharge. The deeper the depth of discharge
the fewer cycles a battery will deliver. Conversely, the shallower the depth of discharge the more cycles a battery
will deliver. To optimize the health of your battery, limit discharge to 80%.
The performance and life of a battery will vary with application, usage, 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.
Operating batteries above 27°C will yield runtimes above the rated capacity and operating batteries below
27°C will yield runtimes below the rated capacity. Cold temperatures can significantly reduce battery capacity.
Although higher temperatures increase the battery capacity they also accelerate corrosion and reduce overall
battery life.
2.3 | BATTERY MAINTENANCE WET CELL BATTERIES
If this unit is equipped with a deep cycle 12-volt Group 27 battery, the care and maintenance of your battery has
much to do with how well this unit functions. Battery wiring and water level should be checked monthly. Do not
overfill. When the cells are too full, fluid will seep out when charging. The solution is at its proper strength when
the battery is manufactured. Use distilled water and keep fluid up to proper level. When required, water should
be added to battery after charging, unless water level is below the plates.
• Slide cabinet open to access battery.
• Remove battery caps and check fluid level.
• Fill each cell (if needed) to split ring with distilled water.
• Reinstall caps.
• Wash all dirt, debris, acid, etc., off battery whenever corrosion is detected. Use a solution of 5ml baking soda
per 0.95 liters of warm water.
• Coat terminals with a commercially available coating.
• Close cabinet and latch in place.
