Kat's Battery Heating Pad for Group 48 Battery in a 2013 Chevy Silverado 1500

Updated 11/09/2026 | Published 11/07/2026

Question:

Will the Kats Heaters KH22400 [8 1/2inch L x 5 1/2inch W] work with a Group 48 battery [11inch L x 6 15/16inch W] used in a 2013 Silverado 1500 WT ? This will be installed in the rear battery tray on the passenger side. PS. Mice chewed into the battery blanket I used last year, so using a pad under the battery will make it harder for them...

Hey Louis! Yes, the Kat's Heaters Battery Heating Pad # KH22400 will work with the Group 48 battery in your 2013 Chevy Silverado 1500. Although it's listed for Group 24 batteries, the 8-1/2" x 5-1/2" pad will fit underneath your larger 11" x 6-15/16" battery. It doesn't need to cover the entire bottom to keep the battery warm.

Just make sure the pad sits flat in your battery tray. If the tray has a perforated or uneven bottom, Kat's recommends using a piece of sheet metal between the tray and heater.

Where are you located that you're dealing with those colder temperatures?

I'm in the south-central Wisconsin banana belt. Temps in the winter are usually in the 10s or 20s, but if and when the Alberta Clipper drops down in late January or February, we can dip down to minus 10 or less for a week. No garage. I looked into a block heater, but IIRC, the 2013 Silverado 1500 ECM looks at the block temp, and if it's too high after 8 hours in the cold, it assumes something is wrong.

@LouisO those Alberta Clippers can bring some brutal temperatures! With your truck sitting outside all winter, the battery heating pad sounds like a good way to help keep things warm without dealing with the block heater concerns.
