SECTION 2 | MAINTENANCE
2.1 | 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 80°F (27°C) will yield runtimes above the rated capacity and operating batteries below
80°F (2rC) 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.
2.2 | 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.

2.3 | CHARGING THE BATTERY
This unit is equipped with either a deep cycle 12-volt AGM maintenance-free battery or a deep cycle Group 27
battery.
Batteries should be fully charged after each use. Opportunity charging can be done but the batteries should be fully
charged at least every other day if they are used daily. Charge in a ventilated area as gases may be released through
the pressure relief valve if the batteries are excessively over-charged.
NOTE: The surrounding temperature greatly affects the power reserve within a battery.
EXAMPLE: A battery that is 100% charged at 80° F (27°C) drops to 65% at 32°F (0°C) At 0°F (-18°C), this battery will
drop to 40% efficiency.
Do not operate unit while charging. Shortened battery life will result.
•
Park the machine on a level surface.
•
Plug charger into AC outlet until charged.
•
For best battery life, leave charger plugged in until machine will be used again. The charger will maintain the
battery charge
BATTERIES GENERATE EXPLOSIVE GASES. KEEP SPARKS AND FLAME
AWAY FROM BATTERIES. DO NOT SMOKE WHILE CHARGING.
DO NOT OPERATE UNIT WHILE CHARGING
NEVER ADD ACID TO BATTERY!
