Battery replacement

I have four 8D batteries now. Two chassis and two house. Is it ok to get deep cycle for all four? Was looking at something like this. The chassis batteries I have now are 1440 cold crank amps. These are a little less at 1370cca

  • Where some of you people get your information is highly suspect, but I did do a whole lot of electrical upgrades to performance cruisers (these are usually retired racing sloops), and ALL 8D are about 170#. A single 4D is only about 130.

    While I don't know what you are starting, but if it takes more than one 8D, figure out what you are doing wrong. As a licensed ship's engineer, I know what it takes to start an engine.

    Also it shows that you googled them. Can you pick them up nearby, or do you have to drive a long ways? Most shippers do not handle batteries, as when the tip or leak, they become a huge problem. AGM batteries will not leak, perhaps that is why they can be shipped. However packages over 100 pounds are not shipped by places like UPS, unless they are on a pallet.

    If the L6 terminal is your standard car size battery terminal then it should work out well. Yet if it is a 3/8" bolt type terminal, it might be a little small for the starting amperage to go through it. Being designed for primary standby use, it might have either terminal. . .

    I happen to like golf cart batteries, with a 220 amp hour capacity in two easy to lift 67 pound packages. I run Trojan T-105 batteries. Trojan is another popular battery supplier. Check your local golf cart company, they might be able to supply your batteries, and by adding your 4 batteries to their order, it can bring them into a special pricing - because of the larger value order. Normally Trojan delivers on their own trucks to many locations.

    Good luck!

    Would two of these be equevellent to two of the 8Ds?




    Mike: You really only need a single 8D for starting and that doesnt have to be an AGC type. For the rest of the batteries they do not NEED to be 8D and 4 of those 27 series wired together are more than adequate for coach juice

    I know but for some reason the deep cycle are a little cheaper.

  • Hi Mike

    The battery you selected will be fine for your purposes. If you have really deep pockets consider moving to LI chemistry.
