Frequently Asked Questions

Can I use my old charger with this lithium battery?

No — Antigravity recommends only powersports-specific lithium battery chargers to avoid damage and maintain the warranty.

What's the warranty on this battery?

3-year pro-rated, nontransferable warranty. You must register the battery with Antigravity within 30 days of purchase for coverage.

Will this work in a modified or internally worked V-twin engine?

No — Antigravity expressly prohibits use in internally modified V-twin engines. The warranty is void if installed in these applications.

How much weight does this save compared to the stock battery?

Most OEM motorcycle lead-acid batteries weigh 5–7 lbs. At 3 lbs, the Restart saves roughly 2–4 lbs depending on your bike's original battery.

What happens if I run out of power on the road?

The built-in jump-start feature allows the battery to supply enough current to restart the engine even if the main charge is depleted, keeping you from getting stranded.
