Battery replacement

[Joedert]

I have a 2019 LTZ with 6.2 15,000 mi. Past the 3yr 36,000. It’s just sitting in storage for now waiting for me to relocate this spring. I have someone starting it every couple weeks and they have to jump it. My question is is there a better battery then the factory GM one? Or will the local auto parts store work. Thanks

If it's just sitting I'd look at a small battery tender. It keeps a low current on the battery to keep it charged while sitting.

Better is tough, the lead acid batteries are nearly the same.

 

There are 3 major manufactures of batteries in the United States, it basically makes no difference on who you bought a battery from. They are all made to very very similar specs and only the color of the case and the label is the biggest difference between them.

 

If you want to switch away from a lead acid battery I would suggest a AGM (absorbent glass mat) style battery.

 

The AGM's are geared towards very well equipped vehicles with lots of electronics because they will handle it better and should last longer overall than a lead acid battery. They do run about $50 more than a standard battery and right now they are pretty hard to find too.

The batteries in our trucks are the AGM battery not the typical lead plate battery they are alot better battery then the lead plate battery, but it takes them awhile to become fully charged so starting truck up for say 1/2hr does nothing to charge them you're really running the battery down even further by doing so. To get them up to full charge the truck would have to run for hours for a completely run-down battery. If you get a battery tender or charger MAKE sure its compatible for an AGM battery. A typical charger when on an AGM battery will burn up the battery do to it not shutting completely off when the battery reaches full charge. A typical lead plate battery should not be installed in vehicles that call for an AGM battery as the charging system in our trucks and vehicles that have that type of battery are very complex.

AGM's charge faster than lead acid batteries according to Interstate Battery.

Also the 2019+ trucks came with both style batteries from the looks of it. You can buy either or. GM Parts Direct and same with Napa online list both options for these trucks.

 

Fun fact too, GM only lists one alternator for the V8 trucks too. So the charging system is the same for both batteries. They also already have a smart charge system that is PCM controlled, been that way for 15 years now. Not trying to discredit the above post but it's not as complicated as he made it sound.

Mostly likely Op has an AGM battery.

 I’m going to try a new Odyssey AGM along with the tender. It’s also sending me a Onstar report sayin the antilock brakes and power train needs attention ASAP. Hopefully it’s do to the low voltage.

Just purchase a battery tender for an AGM battery and you will be fine.  No need to get paralysis through analysis.

A low battery will cause all sorts of error codes and messages to pup up.  Charge the battery or get a new one and put a battery tender on it and you will be fine.
