My FinePix A203 camera no longer "remembers" settings after replacing
batteries. I found there is small internal cell battery inside for
backup which no longer serve its purpose (0.8 volts only).
Unfortunately it needs to be ironed out to replace it.

I can not found a replacement of it, its dimensions are approximately
6.3 x 1.3 mm, the only number I can see on the battery is "272X" where
X can be 0, 6 or 8.

Thanks in advance.
