What You’ll Notice

• Cold starts: Formed plates and a slow charge mean it cranks instead of clicking.
• Holds charge: Sits all week and still fires when you’re ready to ride.
• Rough use: AGM shrugs off vibration, washboard roads, and trail hits.
• No mess: Sealed. No acid. No water to add.

Our Super Charging ProcessLearn more

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. 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, keep it on a smart maintainer. That habit keeps it topped up and ready.

FAQAnswers

Do I need to charge it first?

No. It ships charged and ready.

Why use a maintainer?

Machines sit. A maintainer keeps it topped up so it starts when you need it.

Where’s my model number?

On the face label (e.g., YTX9-BS). This BRS9-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.
