Matt,

As we discussed yesterday, engine batteries usually last about 2 to 4 years. My guess is that yours are more than 2 years old. I would have a battery shop load test the batteries after you have recharged them. They probably need to be replaced. Give Newell a call and find out the cold cranking amps needed; I think it is about 1000 to 1100 CCA.

I installed a Power Pulse device on mine. It sends an electrical charge thru the batteries every few seconds and prevents sulfation from occuring. When sulfation occurs a build up of sulphur(I'm guessing here) attaches to the battery plates and this causes the battery to become less efficient. My batteries have lasted 4 years almost to the month that I first installed them. So I feel that I got double the normal life. Not bad for an $80 investment.

Google Power Pulse battery savers - it's a good investment. Newell Coach sells them also.
