Generac A0010137452 Battery for Next Generation Standby Generators
A0010137452 is Generac's battery for its Next Generation air-cooled home standby generators (2025 and later): a 12-volt AGM PowerSport battery, Group 30L, 400 CCA minimum. Generac lists A0010137451 for the same position and sells the mounting tray separately as kit G00735230. The spec sheet for the 22–28 kW Next Generation units words the requirement as "12 volts, AGM Powersport Battery Group BTX30L 400CCA minimum" — BTX30L and Group 30L are the same battery. It does not fit a Guardian 10–26 kW: those take a Group 26R wet cell (0H3421S) or a Group 35 AGM.

Is my generator a Next Generation unit?
Next Generation is Generac's 2025-and-later air-cooled line. The quickest check is the model number on the data label inside the lid; our maintenance kit page lists the Next Generation model numbers Generac publishes. If your unit is a Guardian 10–26 kW, this is the wrong battery — go to the Generac battery replacement guide for the Group 26R and Group 35 options.
A0010137452 or A0010137451?
Generac's support article lists both part numbers for the Next Generation battery. It does not explain the difference, so this page doesn't either. Order whichever your dealer has in stock, and match the specification — Group 30L AGM, 12 V, 400 CCA minimum — if you buy a non-Generac equivalent.
Do I need the tray kit G00735230?
Generac lists the tray kit G00735230 as a separate part next to the battery. Check whether your unit already has a tray fitted before ordering it.
How to tell the battery is actually the problem
Generac's own test is a meter reading at rest: 12.6 V or more is charged, under 12.4 V is discharged, and consistently under 12 V means replace. The charger is built into the generator — don't connect an external charger to a battery that's installed in it.
Replacing it on a Next Generation unit
Generac publishes a separate replacement procedure for Next Generation units. Like the Guardian procedure, it has you remove the 7.5 A fuse from the control panel before touching the battery and refit it at the end. Three details are specific to Next Generation:
- The battery charger's AC input is disconnected by unplugging J6, the 2-wire connector at the controller.
- Both terminals are tightened to 45–50 in-lbs (5–6 Nm), and the red cover goes back over the positive post.
- There is no full setup wizard when power comes back: pressing AUTO returns the unit to service.
The full Next Generation sequence, step by step, is in our battery replacement guide.
