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.
- Soak for full glass-mat absorption.
- 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 keep them on a maintainer after you ride. Many riders enjoy years of reliable starts.

FAQAnswers
Do I need to charge it before installing?
No. It ships charged and ready.
Why include a maintainer?
Machines sit. The maintainer keeps it topped up so it starts when you need it and helps it last years.
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 a charge longer.
How cold will it work?
AGM runs in tough weather. Keep it charged and it handles winter starts well.
