marine starting battery????

[mutron77]

Hi,<br />Is there anything special about a marine starting battery vs a car battery, other than the screw on posts? I want to get my newly carb kitted, impellared, and tuned 90 horse out on the lake this weekend and am a little short on cash for a battery. I see at Autozone that they have "marine terminals" that you can buy in the battery section to add the screw posts to a regular battery. They are $2.99 and I can use a good car battery that I have on hand instead of buying a "marine starting battery" for about $50. Any concerns in doing this? Is a deep cycle battery also good to use for starting?<br /><br />thanks<br /><br />H90

You will be just fine with a car battery. "marine" batteries are a little bit more heavy duty and reliable, but that's really not much of a concern in a lake. My boat has a 5 year old car battery in it...and I'm assuming it had a car battery for 25 years before that. I wouldn't go out in the middle of the ocean with one, but there's nothing to worry about in a lake.

I agree with ZmOz. Stick the terminals on and go for it. The Marine Batteries have thicker plates in them to help with the jarring on the water and such. But your car battery will work fine on the lake for now. Try to get the real thing when you've got the funds and use the car battery as a backup. You don't want a Deep Cycle Battery for starting purposes. A regular Marine Starting or "Duel Purpose" Battery will do the job better.
