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.

Cold starts: strong crank in bad weather when it’s kept charged.
Accessories: runs winches/lights better when the bike’s charging is healthy.
Vibration: AGM construction handles washboard and trails.

Storage: if it sits, keep it on a maintainer so it’s ready next season.

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.
