I have to buy a new battery for my car, what BRAND do you prefer?

Interstate

Costco
Cheapest i have found and good return policy

I just bought one yesterday for my 81 Jeep pickup no electronics on it just plain ol battery it was $199.99 at autozone I’m sure if it’s a more amp battery you need it will get on up to around $350.00 I’d call all my parts places and price check

I've been getting my boat batteries at Walmart, seems to be as good as any, Interstate though is a good name brand...

Check Consumer Reports.

basically all lead acid batteries in the US are made by the same 5 companies and regionally it may not even be easy to find more than 2 available.

find the best warranty , expect that your battery will last give or take a month of the replacement warrantee time period they are engineered to do just that make it past the warranty by a few months.

compare dollars to CCA to warrantee for the best deal

18 months is getting popular as a warrantee , that way if you are typically replacing batteries on the oldest day/week of the year it gets the warrantee up mid summer when it isn't likely to fail.

a battery maintainer any time you are not using the car daily helps to make them last longer , slow charge them and keep the cook off to a minimum.

if you look at 2 batteries same company same size as an example a
Napa Proformer #65 the 18 month is 675 CCA and 41.5 pounds $140 = $7.77 a month
and the
Napa Legend #65 24 month is 850CCA and 46.5 pounds $200 = $8.33 a month

are 150 CCA worth 56 cents a month you decide.

Deka, made in PA last I knew

Anything other than a Neverstart at Walmart !

I favor DEKA or Interstate and usually go with the AGM in my trucks and motorcycles.

Thanks for the feedback!
