Battery for 1975? help!

Currently, I'm restoring a 1975 29ft - centre bath Land Yacht... I need to buy a new battery. Any thoughts on what size/brand/where I can buy one?? I'm in Canada, thanks.

I use wet cell or flooded batteries in the group 27 category. They usually range from 105 amp hour to 115 amp hour capacity. I've used a Trojan 27TMX with good results. I used two Delco Voyager maintenance free batteries in my '77 Excella 50, one in each front battery compartment and they were going strong over 4 years later. Some on the forum like the Lifeline sealed batteries but they are more expensive.

airbass,

Welcome to the Forums!

It depends on what your plans for the trailer are, and how much electric use you plan on. AGMs generally hold their charge better and re-charge faster, while they cost more and are generally longer lasting. Also depends on if you plan on adding solar at some point, when AGMs make the most sense.

My personal preference are the Lifeline 6VDC golf cart style batteries for their heavy duty capacity and extended draw-down characteristics. Others have different opinions......... YMMV!

The battery compartment on my 75 Trade Wind is large enough for a grp 27 battery. Since I only have room for one, I went for the best. I have a grp 27 Lifeline AGM.

We have a group 27 in our '74. If you aren't going to be doing much for the next couple of years except working on the trailer in the driveway, probably an inexpensive group 24 will be enough. Eventually, though, you'll want the bigger better battery, but if it's more than a couple of years down the road, you might as well save a few bucks.
If you're going to be using the trailer immediately, then go with a quality name brand group 27 deep cycle battery. If you still have the original converter (Univolt), I wouldn't put an AGM in it.

If you still have the original Univolt in it,,,,,I wouldn't put anything in it...............that is before you change the converter to a modern, electronic switch mode unit with 3 stage charging

I took the simple route - a big 100 or 105 amp hour RV battery from Canadian Tire. So far it's working fine.

Lewster's got a point; keep an eye on battery fluid levels because the Univolt might boil it dry if you leave the trailer plugged in.
