Frequently Asked Questions

Can I use a standard lead-acid battery charger with this lithium battery?

No — Antigravity recommends using only a powersports-specific lithium battery charger to avoid damage and warranty voidance.

Does this battery really have jump-start capability?

Yes — the integrated jump-start technology allows you to start a second powersports vehicle or emergency device without needing external jumper cables.

Will this void my warranty if I have a modified engine?

Yes — Antigravity will void the warranty if the battery is used with internally modified V-twin engines. Stock or mild cam/bolt-on modifications are typically fine.

Do I need to register the battery?

Yes — registration with Antigravity is required within 30 days of purchase by the original buyer to activate the 3-year warranty.

How much lighter is this than my stock battery?

At 6.3 lbs, the Restart is significantly lighter than traditional lead-acid V-twin batteries, reducing overall bike weight and improving handling.
