6-Volt Lithium Battery

The Antigravity AG-802 is a reliable Lithium 6V Battery in an ultra compact case. It measures at 4.25″ Length x 2.25″ Depth and 3.75″ Height (to the top of the terminals). The current 6-Volt lead acid/batteries offered on today’s market are extremely unreliable and really not worth the effort as replacements. The AG-802 is a reliable replacement to your old 6V battery, with great performance benefits.
