ODYSSEY PC680 Battery. This lightweight battery is suitable for all cars - we have personally used it on V8's to K20's. It is an ideal replacement as you can relocate this battery in tight locations whilst drastically reducing your vehicles kerb weight – up to 7kgs over a standard battery. We also offer mount brackets should you need a fixing solution. Although it is smaller it doesn’t give any loss of performance! Installation is easy as it has M6 threads and bolts on each terminal.
