Topic: Want to replace my Battery
in Forum: C3 Electrical
Thanks for the info Gunslinger. I noticed the spiral shaped cells, so I knew something was different. The car came with the Optima aready in it, so I really don't know how old it was. The prior owner passed so I can't ask.
I guess what I need. as well as many others, is a battery that can sit for weeks/months and not fail from not using it.
I put a marine battery in because I've had really good luck with all my boat batteries, they really sit a lot and never seem to fail cold/hot/ old or new.....also last well past the expected lifetime spec.
My 2 cents...

I still like the Optima and that's what's in my '78. A lot depends on your needs and how long you intend to own your car...the long term or not.



Well explained, good job. You must be from Tennessee......
I have 10 yellowtop Optima 55AH bargain blems on my boat inverter system on Center Hill, great setup, but not enough AH..., going with golf car batteries this year, 10 6V Titans for 1000AH, I think.
I agree, the yellowtop Optimas don't hold up as well to 14.7 volt charging. Red tops are best for general automotive aps. Interstates are as good a wet cell lead acid battery as you can get.

Dave(Autom8r),
Agreed about the capacity of the Optima for your application... the golf cart batteries ought to do you justice. The golf cart(GC) batteries have much more capacity/reserve than the Optima, which in your case is what you are after with an invertor system. Interstate does carry GC batteries too, model U2200, and there is larger batteries(physically) with more capacity. In fact, there is one that is the same width and legnth, but taller, about 14 inches tall, compared to the GC's appx 10 inch height. The model number on it is U3050. In the Center Hill area, you would be serviced by Music City IBS, and, if you know of a IBS dealer in your area, they can order those for you... http://www.ibsa.com/www_2001/content/products/product_6volt. asp?mscssid=G3MGS9U3DU6C9M4HNGJTV2GCSKB13L11&js=1
link to specifications for those batteries.. least one thing, the golf cart batteries, are roughly half the cost of an Optima.. hope that helps some.. if i can be of some help, let me know.
Thanks for the link.
I bought the Optimas 'cause they were a bargain at $30.00 each as blems, didn't go too wrong as they have worked for 2 years.
I am going to put a noisy sound system on the flybridge this spring and can use a couple of the Optimas there for plenty of power reserve for the 1200 watt system.
