(Please note if you use older bikes from the mid 1990's and earlier you must update the charging systems to a modern voltage regulator. Damaged voltage regulators can over charge and damage lithium batteries)

Product Description

The Antigravity ATZ7-8 Lithium Motorsports Battery is an Hi-Power Lithium Replacement for the OEM Lead/Acid YTZ7S found in so many bikes including most all Enduros. But the Nano-Phosphate Lithium Antigravity ATZ7-8 offers massive weight savings over Lead/Acid version and has over TWICE the cranking amps resulting in much better starting performance with a faster turn over of the motor and higher voltage on start up. In addition the Antigavity Battery offers a big weight reduction.

Best uses

  • Capable of every day use in bikes up to 600cc
  • Race use for Enduro and MX electric start bikes up to 800cc.
  • Race and Track Day use up to 1200cc (If you have a higher-performance motor choose the Antigravity AG1201)
  • Custom builds like cafe racers or small bore customs up to 800cc. (Please note if you own an older classic bikes from mid 1980s and earlier you should update the charging systems to a modern voltage regulator if you have the older style system with a voltage regulator. Damage can occur if overcharged.)

Please note

You must only charge our lithium batteries with a lithium specific battery charger, (such as the Optimate battery chargers offered on this website) the use of any other type of battery charger is likely to damage the battery and void the guarantee.
