My AntiGravity battery has 900 CCA and does an admirable job at spinning the engine on startup.
Antigravity ATX20-HD Lithium Battery
Antigravity seem to be the very best Lithium batteries for motorbikes. Unfortunately it's not easy to get one here in Europe.
I have to think wise about my battery too.... I didn't start my M3W for a month and now the original Banner is at less than 9V... Being just two years old.
Despite the car is still under warranty, instead of asking the Morgan dealer to replace it fo a new one (I bet it will be a Banner again), I'm thinking about investing in a nice Lithium one. I've hear very good comments about the Magneti Marelli ION-15. Expensive, but apparently extremely reliable.
