BATTERY MOUNTING
A loose battery increases damaging effects of vibrations and is more prone to short out.
BATTERY DISCHARGE LIMIT
Discharging below a 20% state of charge cuts down the battery life and the number of cycles available.
At 20% state of charge, specific gravity of 6V battery should be 1180; and 1220 for industrial battery.
CHARGING AREA
−
Always charge battery in a well ventilated area set for and approved for charging.
−
Never leave a charger connected for more than 20 hours.
FREQUENCY OF CHARGE
−
When a battery is discharged to its 20% state of charge, it is best to charge immediately.
−
Batteries require a low current equalization charge (min 4 hours) at least every week, to equalize
battery cells, improve battery performance and life in number of cycles.
−
Never leave a charger connected for more than 20 hours.
STORAGE
−
Keep the battery from getting cold, it would loose its capacity.
−
Let the battery warm up before charging.
−
Charge batteries in “stored” vehicles every month.
DEFECTIVE BATTERY
Check specific gravity of each cell; if a cell is shorted, voltage drop may occur only when there is
current.
