What battery does a Cummins air-cooled standby generator use?

A Group 51R, 450 CCA battery, rated at an ambient temperature of 32°F. The Cummins part number is A052Y816. The battery is bought locally rather than shipped with the generator, and it is the single most common cause of a standby generator failing to start.

Do I need the extreme cold weather kit in Texas?

The standard air-cooled units start and run down to 0°F out of the box, which covers a normal North Texas winter. The cold weather kit, part A054B984, extends that to -40°F. It matters for events like February 2021 where the cold and the outage arrived together. The AE and ACE models already include it, so you do not need the kit on those.

What is in a Cummins preventative maintenance kit?

Part A054H068 contains the parts for one scheduled maintenance interval on the air-cooled range. Using the factory kit keeps the service record clean, which matters because documented maintenance is normally required for a warranty claim.

Accessories and parts

Factory part numbers for the air-cooled Connect range, so you can check exactly what you are being quoted. Some of these belong in the installation quote, some you will buy once a year for the rest of the generator’s life, and one of them is the reason most standby generators fail to start.

On pricing

We publish a price for every generator and every transfer switch we sell, because those are the numbers you can compare between dealers. Accessory pricing we quote against your job rather than list, for a reason worth stating plainly: most of these are specified at the survey, several are cheaper bundled into an installation than bought separately, and a mounting pad quoted without knowing your ground conditions is a guess.

The part numbers are here so you can verify what you are being charged for, whoever you buy from. If you want a price on any of them, ask — we will give you one.

Part numbers are from the Cummins published specification sheet for the air-cooled Connect range. Download it from Cummins. Liquid-cooled and diesel accessories differ.
