Marv, I have a battery tender ( for 2 batteries ) I use on my RV batteries. But it will only work on the truck if I disconnect one of the batteries. With both batteries hooked up it showes both as being charged. It maybe too smart for me.

 

In September of 1998 we bought Alabama-build SUV that was equipped wit Spanish-made battery . The battery never had charger hooked up to it, left the truck only for other jobs, never had water added, was left sitting for 5 weeks at the time on several occasions, yet it was still working in September of 2010 when my son had to jump it twice on cold morning and finally decided to replace it.
I had several other experiences over the years where neglected batteries lasted longer, than those charged on the garage shelf.
Strange thing, but it does happen.

 

Bob,

Are the leads from the tender hooked to just one battery's terminals, or positive to one's positive terminal and negative to other battery?

No, It is a Dual battery Deltran Battery Tender. It has 2 pos. and 2 neg leads. I hook it up, 1 pos and 1 neg to each battery. I think it sees the other battery being charged and assumes it is the battery it is charging. I hope that makes sense. If I disconnect 1 ground cable it works fine

 

I found this. You might find it interesting.

 

I do yeah one close not sure how old this post is but I work for the company that delivers the batteries for Johnson Controls pending on when you bought your battery it may have been delivered by an interstate dealer before it would have been delivered by one of my drivers. Jci builds batteries to customer's specs they supply Sears interstate AutoZone Walmart some orilleys and some napas they own optima batteries I have had great luck with interstate batteries but I get them for dealer cost from the dealer we buy batteries for the trucks and liftgate trailers thru plus send him every junk battery I come across

 

Wholly thread-revival, Batman, and with world-class run-on, unpunctuated sentences, too!

marv,
i have been to costco in last 10 years and i or we have never bought a battery from there. i have a napa orbital gell cell. in my ranger.

 

2-3/4yrs...70k on my Costco batteries.

 

Classic!

 

I just replaced my Costco batteries 2 month's ago, with 2 NEW Costco Batteries! Love them!

 

I just called my local Costco, and they don't have the group 65 batteries. Kind of surprised by that, and he said they all pretty much carry the same batteries. Anyone in the Tampa area get one from them, and can advise?

 

They don't call them "Group 65", but they have them.

Ask them to actually look up the one for your truck in their catalog by THEIR number.

They'll have them. I'd guess at least a dozen of them.

They just don't use the more-conventional numbering system.

Ok, thanks.

 

Ask for item #12866 or anything that may have superseded that item number.
