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 your battery to last 8–12 years? After you park, plug in a smart maintainer.

Do I need to charge it before installing?

No. Every battery is Super Charged, tested, and ships fully charged.

Will this fit my machine?

Yes, if your current battery code matches the YTX20-BS class (ATX/BTX/DTX/ETX/CTX/CYTX/PTX/GTX20-BS, etc.) and your case size and Type 4 terminals match.

How cold will it work?

Our Super Charged AGM handles tough weather. For maximum reliability in the cold, keep it on a smart maintainer between rides.

AGM vs. Lithium—why choose AGM?

Super Charged AGM batteries tolerate cold weather better, work with stock regulators, are designed to OEM specs, and can last 8–12 years when kept on a battery maintainer.
