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. Let it soak for full glass-mat absorption.
3. Slow, 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, plug in a smart maintainer. That habit keeps it topped up and ready.

Riding Techniques

Ways to ride that help the battery.

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 maximizes lifespan.

Where’s my model number?

On the face label (e.g., YTX12-BS). This BRS12-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 it on a maintainer.
