Many owners have experienced a broken battery clip with their X1, X2, X-E, X Vario or X camera (the small grey plastic retaining clip inside the battery compartment). Leica service in The Netherlands was kind enough to send me a new clip for free. While putting it in, I looked for a way to prevent this from happening again. I think the problem is caused by the rather heavy battery which, after a few years, is too much for the quite fragile clip to handle when the camera is put down on a solid object such as a table or other impacts. There is a space of a few mm. between the clip and the inside of battery door. The battery door does not support or hold the battery, but only covers the compartiment. The clip takes full impact of the battery mass on each impact. Because of this design, after a few years the clip usually breaks. An easy way to prevent this is to attach a small piece of sticky foam rubber on the inside of the battery door. The foam rubber pushes the battery up and relieves the clip. Any impact is cushioned by the rubber damper. Ergo; no more broken battery retainer clips.
