Any recommendations for 48AGM battery replacements? I see the AC Delco OEM replacement but looking what others have used.


I have a 2015 with 18k miles and can tell its starting to show its age. Slower cranking and some electrical gremlins- tell tell sign.

Got my oem on summit racing think it was a tad cheaper on there, i noticed my dash cam was going off at low voltage quite often in parking mode.

I'm getting to that point too. I'm going to go OEM and was wondering about buying on Amazon. i.e. Amazon doesn't do the best job of packaging, so I'm wondering if the battery will survive shipping undamaged.

Even though I thoroughly dislike AC Delco batteries, they are our only choice.
I purchased my last my last one from Summit and it was packaged better than my previous one from Amazon.

all the big brand parts stores sell/can order Delco. O'reilley, Autozone etc.

I would stay with Delco because of the valve regulated.

That's my normal route. But I'm thinking that letting Amazon or Summit deliver to my home will save a trip.

How are they packaged?
t
The ones I received were in a heavier cardboard box with fairly thick white foam surrounding the battery on all sides. I would consider it very well packaged. If price is close, I may opt for a local dealer so long as date code is good. The two delcos I got for my Impalas were $40 less on amazon at the time so that’s the routs I went. The other was a Bosch for a Honda and it was about $30 cheaper on amazon than local shops.

Aren’t all sealed AGM batteries “valve regulated”? Is there anything special in the Delco brand battery that isn’t present in other brands or in a battery brand made by the same maker that makes for Delco? (Johnson controls?)

Yeah these are more expense, but they last longer that most run of the mill AGM batteries. Usually two years or more longer! Speaking from personal experience having used both & still do. The batteries plus model does carry a better warranty. Also if buy from their website you get anywhere from a 10 to 20% coupon code poping up to use instantly.

Thx , That’s exactly what I was wondering why I go back to that battery if you could go better would it make a difference in electronics system I mean 12 V will be 12 V with the longevity and endurance is what we’re looking for right so why not upgrade ???

It's NOT a good idea to use a "Dual Purpose" Battery in a motor vehicle. It simply can't provide the same performance as a "starting" battery.
