On a recent week-end trip, I found that both the original and spare batteries, which I had charged fully (and therefore I had not taken the charger with me), went out of power within a few clicks. I was bewildered. Has this happened to anyone? On return, I have again charged them and find that they are behaving normally.
Any way, having lost battery power, the only recourse I had was to shoot using my mobile. Though this has come out well, I cannot stop lamenting how better it would have been with my FZ200 had the batteries retained their power.
