The Antigravity "Small Case" lithium ion batteries offer the most power and performance in the most compact size. They can be used as ultra-light battery for race vehicles to save space and weight, or for fitting into Custom and Performance motorcycles which require a small battery that keeps the look and at the same time delivers enough power to turn the starter. Can hold a charge up to a year provided there are no permanent drains, i.e. accessories that draw power when the bike is off, such as alarms, ECUs, GPS, clocks etc. Antigravity Small Case batteries can be installed in any orientation, feature unbreakable brass terminals and come in different power levels....

Modern gel or Li-Ion batteries offer a significant advantage - they are leak-proof. Those who ever experienced spilled acid in their horseshoe oil tanks will highly appreciate this fact. On the other hand, owners of classic bikes do like the looks of their original energy store and the corresponding cover and mounts. With a Bates BattBoy Battery Box you can have the best of both worlds, because what looks like a period type HM5 6V accumulator on the outside can house a safe, modern battery within. Just hook it with two eyelet wires to the terminals on the bottom of the lid and you are all set. Perfect for 6 to 12 volts electrical system conversions, too. When using suitable Antigravity versions you even have some storage room left for a few small spare parts, safety vest, Cuban cigars, etc. Ain't this one heck of a cool solution for an old problem?
