starting batterys

[kallen]

I have to replace my 15 year old starting batteries (31 series delco voyageur).What is recommended now a days. They are the starting , deep cycle battery. We are in canada so some of the batteries are not available here. Exide was suggested, delco was not. Price range should be around $150.00 each

On their advice I started using group 29 deep cycle batteries, which I got from Walmart (group 27 starting wet cells came with the boat). They were around $99. I have had no issues starting my 270 Crusaders with them. I cannot yet attest to lifespan, as I am only six months (which included the off season) into the port side, and just replaced the starboard battery last weekend. I went with group 29 because that was the largest that would fit in my existing battery box. Since they are not optimized for cranking, I use the parallel switch just to reduce the current draw from each battery, but starting on one deep cycle battery is only a problem when someone shuts off the fuel valve by accident and tries to start the engine. Or so I've heard.

I agree with the Delcos. In our first boat I installed Voyager and got 10 seasons. But when I went to replace I was told Voyager was no longer available. Too good I guess. Our current boat had Interstate batteries in it when we purchased and according to the date stamp on the label are now in their 8th year.

The type of Battery , should be determined by the type of use . If you do a lot anchoring out and use a lot of 12 volt power then a deep cycle is in order for the house battery . Engines should have cranking battery's . If the batteries are used for both then a dual purpose battery maybe in order. I am getting ready to replace a 4D battery myself . I am thinking about replacing it with two 31 series if they will fit in the battery box .
