I know this has been going on for some time . . .
A few years ago, I read that certain brands are no longer pro-rating their batteries. Supposedly, this was because it’s easier for everyone. When the free replacement warranty is up, there are no more calculations to perform, you buy a brand new battery outright.
I know Costco no longer pro-rates their batteries, and I believe this also applies to AC Delco. I’m not sure about anybody else, but I’m sure some of you guys will chime in.
A personal example . . . a few days ago, I noticed that my positive post and cable was showing a lot of corrosion. I bought a new bolt-on cable end . . . possible with Toyota and some others . . . and hooked up my 12V memory saver. As I was removing the cables, I realized the positive post was actually turning. At this point, I know I need a fresh battery.
My Kirkland Signature battery had a “06/14” sticker, so it was clearly 4 years old. By reading the label, I determined it was within the 50% pro-rated period.
So I headed to Costco and swapped the battery out for a fresh Interstate . . . Costco no longer has their own brand batteries, as of a few years ago . . . and paid 50% of the cost of a new one. Not bad, I thought.
Then I looked at the label and determined it has 42 month free replacement period, and apparently NO pro-rated period at all.
By the standards of the Interstate battery, I would have been out of luck at 48 months. I would have paid the full price of a new battery.
Sure, the pro-rated warranty may be slightly hard for some people to figure out, calculate, apply, etc. But it saved me a lot of money, about $40 all told
I’m just waiting for somebody to say I should buy higher quality batteries
That’s fine. Everybody is entitled to their opinions. Batteries sold at Costco are cheaper than most, with the possible exception of Everstart, sold by Walmart. But I don’t do Walmart, and I’m not getting into that. If somebody else wants to go down that road, have at it . . .
