  • HELP! Battery change causes loss of date/time

    I have noticed recently that the date and time has been cleared when I change the battery in my E-5. I have a couple of cheap non Olympus BLM-5s and have a sneaky suspicion it is just one that is causing the problem so I have numbered them and will monitor what happens.
    Has anyone else suffered this issue or have you any advice? I hope it isn't a problem with the camera!

    Do you lose any other configuration settings or is it just the date and time??

      Not that I have noticed, I use My Settings and they reset when the camera starts up, so I haven't spotted any other issues.
      In a hurry on Saturday I set the year as 2012 after changing the battery - a little bit annoying.

        That seems a bit odd, you'd have thought if it losing date and time it would be losing other settings. Is there an internal battery that saves settings when changing batteries?
        It's the image that's important, not the tools used to make it.

          Battery operated devices typically have a capacitor that stores power to cover short term power interuptions such as battery replacements. Other settings generally are stored in memory which is unaffected by changes DURING power interuptions. The capacitor arrangement is used for time/date because it continues to change, unlike the other settings, during the power interuption. Could explain why only time/date are affected.

            I must admit I thought all configs were powered by a charge held on a capacitor ,that's why when all else fails you leave the battery out for about 48hours to get back to default setting.
            That's why I asked about other settings.

            Not had this on my E5.

              You're probably correct Andy. I just thought that MAYBE that could be a reason for losing one but not the other.

                Re: Battery change causes loss of date/time

                I recently packed my E-3 for an outing, which I'd not used for several months, only to find that the battery was so flat that the camera wouldn't turn on at all.Not even to the flat battery screen.
                On fitting a freshly charged battery I expected all my settings to be lost, but I only needed to re-set the time & date.
                I wonder if there are two separate capacitors, the one for the settings which lasts much longer as it just has to retain a memory state, whereas the one for the date discharges quicker as it needs to supply the actual circuit that runs the clock.

                  Maybe 2 capacitors or some settings are saved in memory that is erased when there's no battery in the camera?

                    It should be as Jeff said, important settings are stored in flash memory and less important (date/time, currently selected modes, etc.) are kept as long as there is enough juice in capacitor.

                      I would think that too as the date/time is a clock that needs to continue functioning.

                        Re: Battery change causes loss of date/time

                        Thanks for all your thoughts on this. I haven't taken anywhere near enough shots to run down a battery so I thought I would swap it a few times to see what happened - nothing! The date and all other settings were still there when I switched it back on each time, so maybe it is something to do with the charge left in the battery when I change over?
                        I will keep monitoring it and update here when there is something to report.

                          There is a small button-cell inside the E3 body which needs replacing (like in a computer) to keep the clock chip ticking.
                          I did have this problem of having to reset the date every time i went out with the camera..Its been replaced at the local service centre since..I think i have a picture of the mother-board with the cell clearly in place.
                          I expect the E5 also to have the same button-cell.

                              Yes, and that would explain why the problem isn't occurring now. The first battery was allowed to go dead and then the button battery drained. When the new battery was put in, it recharged the button battery.
