What our technician does differently on a GMC
- We leave the current sensor on the negative cable in place and undamaged, because a cracked sensor gives charging faults that look like a bad alternator.
- On the first-generation Acadia we lift the floor panel behind the passenger seat and refit the vent tube, since that battery sits inside the cabin.
- Duramax Sierra HD batteries are tested one by one and replaced together, as one weak battery drags a new one down.
- We keep memory power on during the swap so radio presets, seat memory and window auto-up do not need setting again.
Signs your GMC battery is failing
- 'Battery Saver Active' appears on the driver display and the truck starts shutting off heated seats and the screen.
- 'Service Battery Charging System' shows up, sometimes with the red battery lamp.
- Start-stop quietly stops working and the engine idles at every traffic light.
- The big V8 turns over slower on the first start after the truck has sat in the sun all day.

The right battery for a GMC Sierra 2500HD
Older GMC trucks ran plain flooded batteries, many with side terminals. From around 2015 the Yukon and Sierra moved to AGM, and every start-stop model since needs one. A current sensor on the negative cable reports to the body computer, which adjusts alternator output to save fuel, so the charging voltage on a GMC moves around on purpose. Duramax diesel Sierra HD trucks carry two batteries wired in parallel.
Duramax diesels run two batteries in parallel and we change them as a matched pair.
The battery for the GMC Sierra 2500HD is matched by size, terminal layout and technology to the one it left the factory with.
Most recent GMC models take BCI group 48 (H6, about 70 Ah) or 94R (H7, about 80 Ah), with group 47 (H5) on some four-cylinder Terrains. Older Sierra, Yukon and Savana years often used the side-terminal group 78. We confirm the exact size from the label on your old battery or from the VIN before the technician leaves.

How long does a GMC Sierra 2500HD battery last in Abu Dhabi?

What warranty comes with a new GMC Sierra 2500HD battery?
A warranty of upto 24 months, depending on the brand and battery model. The fitting date is written on the battery and on your invoice.
Does my GMC need an AGM battery?
Yes, if it has start-stop or left the factory with an AGM, which covers most recent Yukon, Sierra, Acadia and Terrain models. A flooded battery in its place fails early and switches start-stop off. Older trucks without start-stop can stay on a good flooded battery.
Do you need to programme a new battery to a GMC?
No, a GMC does not need its battery coded with a scan tool. The battery sensor relearns the new battery over the first few drives. We check the charging voltage and clear any stored low-voltage codes before we leave.
