Modern gel or Li-Ion batteries offer a significant advantage - they are leak-proof. Those who ever experienced spilled acid in the battery tray, on the frame, on the swingarm, etc. 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 32 amp 12V 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. When using suitable Antigravity versions you even have storage room left for a few small spare parts, safety vest, emergency beer, etc. Ain't this one heck of a cool solution for an old problem?
