Abu - I don't think the battery will start yet. From o/s reports the new Sanyo 3600 cell has good runtime (approx 10 secs more than GP3300 but poor voltage) This is the same problem that the old Sanyo 3300 had. Add this to most probably a higher price for Sanyo cells and it become a no contest. Thanks for the offer of a zapper but I have a pretty good one.
