Last night during FoCal calibrations, the LP-E6 ran down very quickly. I ignored the problem, and put in a freshly charged battery, whihch also ran down in 30 minutes or so. Today, I put in a charged battery, which dropped to 92% after 78 shots at lunchtime. This evening, I noticed that despite not being used, but the camera being left turned on, it had dropped to 46%. Previously, the various batteries have been fine. Has FoCal set something in the camera or what? Any advice please.
ps Last night I was using a 300mm f/2.8 II with a 2xTC III, today with the 1,4XTC III
