![]() Always use a matched charger and battery pack system.A weak battery will cause premature failure of companion batteries. Load testing will pick out a bad battery when other methods fail. Voltage checks (open circuit, charged and discharged) can locate a bad battery or weak battery. Imbalance could mean the need for equalizing is often a sign of improper charging or a bad cell. Hydrometer readings of each cell (fully charged) gives an indication of balance and true charge level. Periodic battery testing is an important preventative maintenance procedure.Either replace will all new or use a good used battery(s). Do not put a new battery into a pack which has 50 or more cycles. In situations where multiple batteries are connected in series, parallel or series/parallel, replacement battery(s) should be of the same size, age and usage level as the companion batteries.Automatically controlled charger should be unplugged and reconnected after completing a charge. Manually timed charger should have the charge time extended approximately 3 hours. Actively used batteries should be equalized once per month. This extra charge helps keep all cells in balance. Equalizing is an extended, low current charge performed after the normal charge cycle. Deep cycle batteries need to be equalized periodically. Avoid charging at temperatures above 120 degrees F or ambient, whichever is higher.Defective and unmatched chargers will damage batteries or severely reduce their performance. Battery chargers should be matched to fully charge batteries in an eight hour period.Proper battery sizing will help avoid excessive discharge. For best battery life, batteries should not be discharged below 80% of their rated capacity.Particular care should be taken to avoid metallic contamination (iron). ![]() (Total Dissolved Solids…parts per million). Water used to replenish batteries should be distilled or treated not to exceed 200 T.D.S. ![]()
