Install, Operate and Maintain Batteries Correctly
Incorrect installation can lead to shortened battery life, as can improper maintenance. Good maintenance means giving the batteries well ventilated air that is as close as possible to 77 degrees Fahrenheit, and making sure that all batteries in the string are getting air within 3 degrees Fahrenheit to ensure that some of the batteries don’t age more quickly than others.
Why? Mixing batteries of different ages or internal resistances can prompt batteries to die more quickly. Regular inspections of the batteries can unveil problems such as loose inter-cell connections and damaged post seals, which can lead to corrosion and even fires.
