+1 for the Hawker, but to be honest the newer technology Batteries are all pretty good and generaly better than the old style standard LA. Pays you money takes your choice, I've always used Hawkers as they've never let me down no matter how much I've abused them. Mya give the KL a try for the new battery in the Pan 1300 though just out of curiosity.
