Frequently Asked Questions

Can this battery jump-start my bike if it dies?

Yes — the built-in restart circuit allows you to self-start the engine without external jumper cables or a second vehicle.

What charger do I need?

Antigravity recommends a powersports-specific lithium battery charger. Standard automotive chargers may damage the battery.

Will this fit my Harley or Indian?

This battery is designed for most V-twin Harley-Davidson and Indian models. Verify your bike's physical space and OEM cranking amp requirement (480 CA) before ordering.

Is the warranty transferable if I sell my bike?

No — the warranty is non-transferable. Only the original retail customer can claim it, and registration with Antigravity is required within 30 days of purchase.

Can I use this in a modified or supercharged engine?

No — Antigravity voids the warranty for internally modified V-twin engines. Stock engines only.
