Common questions
Will this battery work with my stock charger?
No, Antigravity recommends using a powersports-specific lithium battery charger to ensure proper charging and prevent damage to the battery. Standard lead-acid chargers are not compatible.
How does the built-in jump-start feature work?
The RESTART feature reserves a small amount of energy, allowing you to press a button on the battery to initiate a self jump-start if your motorcycle battery dies, eliminating the need for external cables.
Is this battery compatible with modified V-twin engines?
This battery is not recommended for internally modified V-twin engines, as use in such applications may void the warranty. Please confirm fitment with your specific application before ordering.
