    Default Batteries? Deep cycle or ? mini batteries? dual?

    My biggest issue, is where I want to put a battery or 2 (at the back of my outside sponsons) I only have 10"x8.25", I know I can buy a smaller battery than the one I have, but what about a battery box for a smaller battery? Also if I go to a 2 bat. set up, do I need an isolator, or should I just run them one at a time with a switch??

    Here's all the specs for Optima(s). Looks like standard red-tops are around 10X8.

    I can tell you what not to get. Rock Racing battery. I have a ton of money in mount and battery but refuse to get the charger that I learned ater, a regular charger wil kill the battery. I was running with no alt and the battery only lived for a year.

    are you looking for starting batteries or something small to run a stereo?

    small sealed batteries like this work well for backup (~$30-40)

    Pretty much just a starting battery, although a stereo is on my to do list. Maybe I'll hit Rex up and see if he has a battery box that will fit in an 8.25"x 10" space. As far as the deep cycle thing goes, I asked over on scjb and most said not to go with a deep cycle. I'm not real hip on the whole optima deal either.

    X2 on this idea .....red top Optimas can be mounted in any way needed to
    fit, my last boat had them mounted lying on their side to ease hooking them up, unless your trying to save weight go with two batteries with
    the selector switch IMO

    I hear Sams has the best price

    Seriously, go to Costco. They are inexpensive there, and last about 5 years or so. Same as just about any other battery I have used in the past.

    I don' thave a picture of one, but in my sandrail i run a small AEM battery, not enough cca for a boat motor, but would be killer for a 2nd battery to run a stereo IMO. I think they're deep cycle, and made by Centennial?? I'm running two Huge batteries in my cruiser, and am thinking of making the second one a little battery like that one for the radio...i think there are even wheelchair batteries like that. I've actually turned over my stock bbo with it no problem though, in case of an emergency.

    Default Battery

    H2O, I ran a lawn equipment battery (230cca very small, and light weight) in my Daytona. Alt, and no radio. It would fit under the back seat if you run on. The rail kit was long, ran ahead of the engine. I made a holder, and installed it there. Held it up from the bottom. I had a gear reduction starter. I think the standard starters might pull too many amps. I never had any problems. Good luck, schick

    You do NOT want deep cycles for a starting battery.

    They are made to deliver 10 to 20 amps to power elec. motors and things for a very long time, not made to output 200 to 300 amps of current to spin a starter motor over fast.

    From OPTIMA's website FAQs:

    13. Can a deep cycle battery be used for engine starting?

    Yes. If the cranking amps rating is sufficient for your vehicle, there is no reason not to use a deep-cycle battery for starting.
    Besides, most - if not all - of their blue top marine batts are listed as "dual purpose", designed for starting and deep cycle.

    I agree, however, that a yellow top does not belong in the starting position. Can it? Yes. I see it more times than I should. My main argument is that it is money thrown away. A red top fits the bill most of the time. I have ran them down to nothing several times over and they bounce right back. They won't do that near as many times as a yellow or blue, but they deep cycle just fine.
