Product Description

The Reliable Solution for 6-FM-9A and HW-9-12 Battery Replacements

Is your portable generator or backup system failing to start? The 12V 9Ah SLA Battery is the professional-grade replacement for the widely used 6-FM-9A and HW-9-12 models. Unlike standard batteries, this unit is designed with the exact physical footprint and specialized B1 terminal required for a "no-hassle" installation.

Whether you're powering a home emergency generator or a critical UPS system, the 9 Amp Hour capacity ensures you have the energy density needed for high-draw moments. This battery utilizes advanced AGM (Absorbed Glass Mat) technology, meaning it is completely sealed, maintenance-free, and safe to use in any position.

Why the B1 Connector Matters:

Many specialized generators and electronics use a proprietary push-style harness. Our B1 battery type features the correct terminal shape to "click" into your existing wiring, ensuring a low-resistance connection that won't vibrate loose during engine operation.

Direct Cross-Reference & Compatibility:

  • Common Part Numbers: 6-FM-9A, HW-9-12, 6-MF-9A, HYS1290, and FM1290.
  • Application Fitment: Ideal for portable gas generators, jump starters, and specialized medical or security equipment.
  • Performance Upgrade: A high-quality alternative to standard 12V 7Ah batteries, providing 25% more runtime in the same physical size.

Technical Specifications:

  • Voltage: 12V
  • Capacity: 9Ah
  • Terminals: B1 Connector
  • Dimensions: 5.94" L x 2.56" W x 3.70" H (to top of terminal)
