![]() ![]() When not in use, boost every two months.Are Dual Purpose Batteries Better Than Conventional Flooded Lead Acid?.Batteries will discharge when stored, the lower the temperature the lower the self discharge. However, do not store in a location which will consistently be below 32 degrees F. Store the battery in as cool a place as possible.Remove all electrical connections from the battery, including series/parallel connectors.Completely charge the battery before storing.If season use is anticipated, we recommended the following: Inactivity can be extremely harmful to all lead acid batteries.If extreme temperature is an unavoidable part of an application, consult a battery/charger specialist about ways to deal with the problem. Very high temperatures can cause “thermal run-away” which may lead to an explosion or fire. Heat increases water usage and can result in overcharging. Cold reduces battery capacity and retards charging. Extreme temperatures can substantially affect battery performance and charging.This will shorten their life and reduce their capacity. Avoid continuously operating batteries in a partially charged condition. Lead acid batteries should be brought up to full charge at the earliest opportunity.Usually older batteries need to be watered more often…and their capacity decreases. ![]() This means longer charging time and/or higher finish rate (higher amperage at the end of the charge). As batteries age, their maintenance requirements change.Unmatched chargers will cause potential problems. 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).
