I thought I'd find the answer but I didn't. First off, my batteries are well over five years old, wet cell, 12 v. I have a battery
switch for either, both or off. The engine
runs very little during the year, maybe 3-4 gallons.
I only need to start my old Westerbeke diesel
to get off and back on the mooring
a couple of times a week, if that. No overnights. It was getting harder and harder to start the engine
so I bought a SUNFORCE Solar-Powered Trickle Charger
- 350mA .
The engine started more easily but I noticed that I had to add water
to the batteries more often (they rarely needed water
Yesterday the batteries wouldn't start the engine (after a couple of weeks of very hot weather
and not being on the boat at all). The water levels were down a bit. I topped them up and maybe they'll start today but I need a more reliable solution.
If I need to get new batteries my question is what to buy - my use is essentially starting the engine and next no "house" usage. And since I use the engine so little, the only recharge is with a solar charger
Automotive starting battery
(1 or 2) or deep cycle.
Thanks for any suggestions.
Oh yes, I have a 26' Nonsuch.
