Both House batteries bad?

Hi sailors,

I have a 33 Endeavour with 3 batteries- 1 starting battery and 2 as house batteries. I think all the batteries were new in June of 2007. My starting battery is still OK but the house batteries both are not. I do not use a lot of stuff on the house batteries, rarely go out overnight, and keep batteries charging at the dock.

Are house battery types inherently less long lived? Is it odd they both died at the same time?

I am about to replace all 3 just to be on the safe side, due to their age.

Thanks, Saltypat

Surely you use the house batteries more than the engine start battery. Why replace the engine battery if it's still OK? Is the engine battery also charged by shore power or simply by the alternator when the engine is running?

Is it possible that the house bank batteries have been drained too deeply several times and have given up the ghost?

I'm assuming wet cell, would that be correct?

It isn't that house batteries are inherently less long lived...but they are usually used (consumed) differently. In fact, I wonder what is occuring that makes you think the house batteries are not OK? Will they not take or hold a charge?

Lots of questions I know... others will be along to provide their thoughts.

That's 4 seasons out of them. Not terrible, especially if they have been left discharged for any length of time. You state you keep them on charge at the dock. Overcharging can be as bad as undercharging.

Before you spend money on new house batteries, try spending a few bucks on distilled water and check the electrolyte levels in your batteries. First, look at the water level. If it is low, refill with the distilled water then equalize the batteries. This helped rejuvinate my batteries. From there, you have several other avenues depending on the problem(s) you are having.

Constant charging with the wrong parameters can also kill your batteries. If they are on the charger constantly that can be a death sentence if you don't maintain them, distilled water, or have a charger that does not do a float stage charge.

I am assuming you have checked the obvious items such as connections and voltage while charging?
