Westinghouse Generator Batteries

Reliable Electric Start for Your Westinghouse Generator. Westinghouse generators like the WGEN7500 and WGEN9500 are built for high-output power, but that power is only accessible if your battery is healthy. Whether you have a Dual Fuel (DF) or Tri-Fuel (TF) model, these large-displacement engines require significant cranking amps to turn over—especially in cold weather.

At Battery Mart, we provide premium AGM (Absorbed Glass Mat) replacement batteries designed to outperform the original factory equipment. Our Westinghouse-compatible batteries are 100% maintenance-free and feature superior vibration resistance, ensuring your generator is ready to work when the grid goes down.

Precision Fit for WGEN & WH Series:

  • WGEN Series: Direct-fit batteries for the 7500 and 9500 series (including C, DFC, and TFC models).
  • WH Series: High-performance replacements for the WH7500E and WHXC8500.
  • Upgrade Options: We offer high-capacity Motobatt and USA-Made Big Crank batteries that provide more amp-hours (Ah) for more reliable starting attempts.

Tips for your Westinghouse Generator

Remote Start Key Fob

One major feature of Westinghouse generators is the Remote Start key fob. The generator has a receiver that is always "on" even when the generator isn't running, which creates a small drain on your battery.

We recommend a Battery Tender to keep your battery healthy and charged when the generator is not being used. Keeping the battery charged will ensure your Westinghouse generator is ready to go.

Frequently Asked Questions: Westinghouse Generator Batteries

What battery does the Westinghouse WGEN9500DF use?

The Westinghouse WGEN9500 and WGEN7500 series typically use a 12V AGM battery, often cross-referenced with the YTX14AHL-BS or YB9-B sizes. For maximum reliability, we recommend the Motobatt MBTX14AU, which offers 16.5Ah—significantly more starting capacity than the standard factory battery.

Can I upgrade the battery in my Westinghouse generator?

Yes. Many Westinghouse owners upgrade to a higher Amp-hour (Ah) battery. For example, if your unit came with a standard 9Ah or 12Ah battery, upgrading to a Motobatt 14Ah or 16.5Ah version provides more "cranking reserve," which is helpful if the generator has been sitting in the cold or if the engine doesn't fire on the first attempt.

How do I charge my Westinghouse generator battery?

Westinghouse generators have an internal charging circuit that charges the battery while the engine is running. However, because these units are often stored for long periods, we highly recommend using a 12V float charger (trickle charger) during the off-season. This prevents the battery from self-discharging and extends its lifespan to 3–5 years.

Why is my Westinghouse generator clicking but not starting?

A "clicking" sound usually indicates that there is enough voltage to engage the starter solenoid, but not enough amperage to turn the engine over. This is a classic sign of a weak battery. Ensure your terminal connections are tight; if the clicking persists, it is time for a replacement.

Does my Westinghouse generator battery come charged?

Our AGM batteries are shipped activated and fully charged.
