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: Our batteries can last 8–12 years when you plug in a smart maintainer after you park.

FAQAnswers
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?
Our Super Charged AGM performs in tough weather. For maximum reliability in winter, keep the battery on a maintainer when parked.
