(No reviews yet) Write a Review

Replace that heavy OEM 6-Volt lead-acid battery with a reliable, compact, lightweight lithium ion battery from Antigravity.

The Antigravity Batteries AG802 is a 6-volt 8-Cell Lithium Ion battery in an extremely small case. It is made for those who ride classic older bikes that run the 6-Volt system. It is a very reliable compact replacement for the bulky and large 6-volts of the past. The current 6-Volt lead acid/batteries offered in today’s market is extremely unreliable and not worth the effort to replace. Comes with adhesive backed foam to make for an easy installation.
