It was likely that the camera was locked up in some non-standard mode where motors were powered inappropriately. For instance if the SR circuit was malfunctioning the current drawn would likely be within the spec of the battery but the SR system may not be able to adequately dissipate the heat deve

I've never had exactly that experience with a camera, but I've had massive discharges from batteries when a dead short developed in a circuit. I'd be wary of any device that did that once. Those types of problems seldom fix themselves. On 7/6/2014 12:09 PM, Ralf R Radermacher wrote: Michael'

Batteries get damaged and bad things happen. I recently dropped a battery on some gravel and after charging it up was a little freaked out when my K-5 IIs started mirror flopping all over the place. After I finally calmed down, I realized that the battery was overcharged as switching to a nearly de

Michael's K-r has been lying switched off on the table this afternoon and when he lifted it after a while the whole camera body was really hot and the battery was almost discharged. I admit I'm nore than a little alarmed and I'd rather not want to know what would have happened if this had occu
