Anyone add a starting Battery

And what has been your time span with the 4D batteries, I believe my are getting weak. Just over two years old.ThanksSkipper Ken

Ken,Our original 4D batteries are coming up on their 4th birthday and seem to be holding up just fine. The boat is hooked up to shore power whenever at the dock, and being in California this is year-round. I do keep the refer on so that is drawing from the batteries and the charger (Charles model) replenishes what is taken out. I also keep the battery switch on 1 for odd months (Jan, Mar, etc) and on 2 for even months (Feb, April, etc). This way they get a month "off" every other month, and, if there was a shore power failure it wouldn't "kill" both batteries. And, I check the battery fluid level frequently (every month); usually not much water is needed. If it was needed it'd probably indicate a charger problem.As for a starting battery, I've considered adding one but haven't gotten to it. The way we use the boat there really isn't a need for it at this time.Happy Sailing,GaryC310 #230 "Rhythm"

Over six years on our original batteries and they seem to be as good as new. I use a link 10 to monitor them. I don't leave the charger on unless they need it, but I do keep them fully charged.

have 8d's. We have hull 312 and have two 8d batteries under the port settee. Is it because of the Fridge? I thought all 310's have Fridge's. These batteries are really heavy, really difficult to pull off and put on the boat (as, I would guess they were installed before the deck assembly was added) and when it comes time to replace them, I suspect I may need to take out a small bank loan...would 4d's give me the same performance?

I always thought my 4D's were 8D's...
