I have an 35' egg harbor and quite often i check the batteries and they are all dried up and will start to lose their charge. what might be causing this problem and how might i fix it?
What kind of charger to you have on them? How often do you check the fluid level, and how much water do you have to add? I have 4D's in my boat with a StatPower charger with float function. It will boil off a quart or so of water in two to three months.
i see this problem a lot in the spring. have your batteries checked by someone with the right tools. this usually happens when 1 battery in a bank is bad. could also be a bunk charger.
If all cells are low then likely over charging or overloaded. I check my batteries twice a year but only need a small amount of distilled water one time a year.
hello<br /> most shore powered boats suffer this problem. seems the battery chargers sometimes get carried away. the newer solid state chargers seem to help. thats why battery water level checking is a montly maint procedure especially with on board chargers and shore power. your not at NYCC or tide water boat club are you ?
as batteries age (wear out) they lose their capacity.. in essence as time passes they become smaller and smaller batteries.. this leads to a deeper (relatively) charge/discharge cycle pattern.. which leads to an easier overgcharge situtation which leads to increasing loss of electrolite which all adds up to a battery that starts to die very quickly..<br /><br /><br />i have found the only really reliable way of testing them is to put a known load on them for given a time.. it dosnt take a scientist or special tools to do this.. a fully charged 100 amp hour battery should take slightly less than ten hours to go flat with a 10 amp load on it.. if it goes flat in five hours its half worn out.. if it goes flat in 2 hours its 80% worn out and well and truly in its rapid die off phase..<br /><br />folks continueing to use batteries that are in this (still working) but rapid die off phase is all to common.. <br /><br />trog100
