We don’t rush batteries out the door. We do five things so it works when you turn the key:

1. Fill with 1.265 SG electrolyte to spec.
2. Soak for full glass-mat absorption.
3. Slow, high-frequency forming charge (~900 mA) to form the plates.
4. Rest and verify it holds 12.6–12.8V.
5. Final QC. Ships ready to install.

Pro Tip: Want it to last 8–12 years? After you park, plug in a smart maintainer. That habit keeps it topped up and ready.

• Cold mornings: Strong cranking for reliable starts.
• Accessories: Handles winches and add-ons when properly maintained.
• Vibration: AGM plates and mats resist shock on rough trails.
• Mounting: Mount upright or on its side. Don’t mount upside down.
• Storage: Keep it on a maintainer between rides. Ready when you are.

Keep this battery topped up between rides with the BRS612 smart maintainer — a 60-second habit that helps riders see 8–12 years from our batteries. The eyelet plug adapter makes it plug-and-go: mount it once under the seat, then just connect after each ride.

Do I need to charge it before installing?

No. It ships charged and ready.

Why use a maintainer?

Machines sit. A maintainer keeps it topped so it starts when you need it and helps maximize lifespan.

Where’s my model number?

On the face label (e.g., YTX9B-BS). This BRS9B-BS replaces that size.

How is this different from a cheap battery?

We soak, form, and test each one. No acid splash-and-dash. That’s why it cranks harder and holds charge longer.

How cold will it work?

AGM runs in tough weather. Keep it charged and it handles winter starts well.
