Its getting near the time I start checking my electrical system on my recently purchased 84 C-25. The previous owner has it set up for a dual battery system (guest switch), there is also a Sears trickle charger mounted in the bilge area. Boat is also equ

Yes, the switch, which on my boat is labled "AC Main", should be thrown after the shore power is connected and when you want batteries charged or AC outlets to work.

I would double check the Sears charger. Maybe I'm paranoid, but IMHO anything not mad

You can find a fair deal on marine batteries at Costco. Gel or lead acid they have both.

Whatever you do, get rid of the charger and install a charger is marine compatible, and, be sure to mount it where it is dry and air to keep it cool when charging.

As you are relying on your charger to charge the batteries, and not an alternator on an

I have an '84 as well...the batteries are located at the aft end of the starboard setee. There is a separate battery compartment with it's own acess cover (this is aft of the fresh water storage tank). The battery compartment is isolated from the bilge.

My 78 has a similar set up. Our charger is also located in the bilge area, however is tucked up rather high. To be honest, If the bilge ever fills that high with water, I would have much greater problems to worry about than whether or not my batter char

If you are burning up two deep cell batteries a season than I would seriously have somebody in the business look to see what your problem is

Frank, I don't know how much time you spend on your boat but we've been using ONE battery for three seasons now. Someday when we go to the North Channel and live onboard for 10 days, we'll install a second battery. For day mostly sailing, weekend stays

Duane:

If you're burning out deep cycle batteries because of over-use between charges, or overcharging, you should seriously consider a gel battery--not just because you won't have to replace it very often, but also because it will be much less likely

That brings up the question. Is it possible to overcharge/boiloff a gel battery?? This could be an answer to Duane's situation. One gel battery has to be less expensive then all the deep cells he is buying. Ed on 'Yahoo'

The West Marine catalog has a thourough discussion of the Pros and Cons of different battery types.

On our '85 C-25 we went with a single Group 31, Deep Cycle rated at 105 amp-hours. It lasts us about 5 days, powering the lights, and the AM/FM, CD pla

Gentlemen;

Thanks for all the insight, I think I will go with a deep cyle and see how long it lasts.

Ed:

When you use a gel battery, you must use a charger that is compatible because you can do great damage to them-and in extreme conditions, they can explode.

If you overcharge one you can tell by the case as it will have a bulge in it somewhere-not

Thank you Ken, As I stated in a previous post, both of my batteries are at least 4 years old. So far they are still sound. If I can get another year of use out of them, I would say I have gotten my moneys worth. Perhaps I will look into the gel type wh
