Battery Suggestions

Tried a different dealer and he said that the only thing "they" are making now in that size is a 48GHR, #88866212. Label shows 770 cca rating and 75 Ah and 42 month replacement warranty. I have not been able to find written information on the part number.
I tested it without charging it and got 875cca on the tester so I am optimistic.

Thanks for all the input.

Dealer's price usually includes installation, if you have time. They also have coupons on their website every other month sometimes for them as well.

No coupons right now except for the low end battery. The dealer that installed my old one charged $25 extra.
I just did it and it's no big deal once a strap gets under the battery to help hoist it out of the cranny.

Curiously, my O'Reilly's has the others in stock and that one doesn't show up on ACDelco's website, the others still do. Must be very new. Well, good thing is the problem is solved and the wife is safe again!

O'Reilly does list a 48GHR145, 88866162 but it is not linked to being available for my trucks.

I dropped AC Delco a line to see what's up. One number on the label is a GM reference and the other an AC Delco.

Oops, didn't read far enough to see you made a decision. Good luck.

I recently put in an Interstate AGM and a rebuilt alternator. All is fine now. However, the first Interstate AGM appears to have been bad out of the gate. The volt meter was reading high e.g. above 15volts and didn't seem to "kick" down. This is something to watch with a "new" battery. The Interstate store where I go swapped it out for free and all is good now. Keep in mind that the computer is involved in adjusting the charging.

I have read that an AGM calls for a different charging curve than an AGM and should only be used if the charging circuit is designed for AGM. I have been getting batteries from Costco, which in northen virginia are made by Interstate and give good service. I just replaced 4 in my boat, after 6 years, but that is light service as they aren't subject to heat or many charge cycles.

A deep cycle battery, like some marine batteries, can withstand being recharged from a dead condition more times but they may not be available with enough cold cranking amps.?

Everstart maxx from Walmart. Cheapest price and the same exact battery as advance auto sells. I was steered away from agm batteries because the way the charging system works.

Got one in our Subaru; three years and still kicking. Unfortunately they seem to be hard to get around here now.
As for Interstate, I've had nothing but early failures with any I've tried and think they are over rated. I'll never buy another.
The replacement AC Delco Gold (43 mo) that I just replaced lived just shy of 7 years.
As I wrote, I replaced it with the same, or close to it.

Go with a good one. I put two of these under my back seat.

i foind the location of the battery is close to the curved body brace so use duct tape over the terminals when installing the new battery....then remove once battery is strapped down....

I installed two of the largest batteries that would fit into my battery compartments last time I replaced my battery.

Your battery did it's job and was telling you it was getting tired. It didn't strand your wife, you did! LOL

Walmart is out of batteries because they are changing skus and prices are doubling, an $88 battery for the Montana Saturday night was now $125 or so on Sunday. We went to O'Reilly's and put an $88 ACDelco battery in it instead. I can't imagine that car last another 18 months! But then again, I thought we'd only have her another year, 6 years ago!

Anyhow, the 42 month ACDelco 48PG is $166.99 at O'Reilly's right now and the 48HPG is $173.99. The latter has a higher reserve capacity (15 more minutes) and a little more than 6 amp hours more juice in it.

I think it great that you got 7 years out of any battery. Down here in Florida we were lucky to get two years out of them before RVC was put into the cars. My last 30 month ACDelco battery went 48 months, 48K miles and 1700 hours. It was replaced with a 48HPG last Christmas.

The charging systems in the 900s were not programmed to handle AGM batteries and judging by the comments on this and other forums, they do not last as long as they could have because, if memory serves, they like to be re-charged at a faster rate. This may be why GM uses 220 amp alternators now. ACDelco makes AGMs too, but they are not listed as compatible with our trucks though plenty of folks use them without issue.

I wonder if an alternator upgrade would help charge agm batteries? I imagine it wouldn't be plug and play anyway.

This has been my experience. With the OEM alternators I had new AGM batteries fail in both trucks in less than a year. With this alternator installed in both trucks now, I'm on year 5 in one and year 4 in the other - both AGM batteries of the same brand and size that previously failed. It's a datapoint of 2, but I'm 50K miles in and no more problems.

Yes,
and
all things being equal, AGM batteries charge faster (less resistance) than wet cell batts.
