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:

1. Fill with 1.265 SG electrolyte to spec.
2. Let it soak so the glass mat pulls in the electrolyte.
3. Slow, high-frequency charge (~900 mA) to form the plates.
4. Let it rest and verify it holds 12.6–12.8V.
5. Final QC. Then it ships ready to install.

Pro Tip: Want it to last 8–12 years? After you park, plug in the maintainer. That habit keeps it topped up and ready.

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.

Where’s my model number?

On the face label (e.g., YTX9-BS). This BRS9-BS replaces that size.

How is this different from a cheap battery?

We soak, form, and test each one. No acid splash-and-dash.

How cold will it work?

AGM runs in tough weather. Keep it charged and it handles winter starts well.
