What You’ll Notice
- Cold starts: Plates are formed right, so it spins the starter instead of clicking.
- Holds charge: Park it all week and it still fires when you’re ready to ride.
- Rough use: AGM shrugs off washboard roads, vibration, and trail hits.
- No mess: Sealed and maintenance-free. 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:
- Fill with 1.265 SG electrolyte to spec.
- Let it soak for full glass-mat absorption.
- Slow, high-frequency forming charge (~900 mA) to form the plates.
- Rest and verify it holds 12.6–12.8V.
- Final QC. Ships ready to install.
Pro Tip: Keeping the battery on a smart maintainer after rides helps it last 8–12 years.

FAQAnswers
Do I need to charge it before installing?
No. It ships charged and ready.
How does the maintainer help?
Machines sit. The BRS612 keeps the battery topped so it starts on the first push 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?
Our Super Charged AGM performs in tough weather. For maximum reliability in winter, keep the battery on the maintainer when parked.
