I am curious to know if you can run a blue top optima in a car it being the only battery?

 

I've been running mine for a couple years. It's enough for my two 15's and I rarely dip below 13.6v (normal is 13.8-14.1) when the subs hit

I left my car sitting for about 4 months, I started it every other month with no problem.

Blue top is perfectly adequate. I also like the extra terminals for running accessories (subs, haloz, etc.)

 

Isnt the Blue Top a marine battery?

 

Yup.

Doesn't matter if it's marine, military, anything, it works.

a search would show that dozens of members, to include me, have been using the bluetop for years.

 

Cool Thanks guys for the info. I have used them on juice before but i know they are intended to run dead then back up and can have problems lasting if you dont but if you all have not had any problems then it is a blue top for me. Thanks again

 

You are right. IDEALY these batteries are desinged to be fully discharged then slowly recharged but the Optima style battery is very robust so Yellow or Blue will be fine.

Red is for starting only, has little to no reserve.

 

^^^yeah, but it's still a bunch more than most other walmart car batteries you can pick up.

basically pick a color and you will get a good product.
