I haven't been using my Leaf Aptus for about 11 months whilst I've been moving houses and countries. Upon unboxing it all and putting it together last night it seems a a few of my batteries are dead - they show full charge in camera but cut out after 30 seconds' use.
However more worryingly, it seems my internal battery is dead. The date and time is reverting to 1st Jan 1981 upon each restart of the Back. It was left without a (main) battery connected - I don't know if the internal one charges or feeds off the main battery at all? I set the date and time and it remembers it whilst on, but any power off and restart cycle of the back and it reverts back to 1981 again. Any images have a date of 1st Jan 1970 on the image info but a date of 1998 in the list-view in-back. 1970, 1981, 1998 - Weird!
I started to notice a few settings were not being recorded a couple of years ago in my post here:
... perhaps this was the first warning sign. The Back is dated 2008 so 4-6 years sounds about right for one of those little button-cell batteries that normally do internal clocks in laptops etc, so I'm self-diagnosing that my internal battery is dead.
The official line from MamiyaLeaf was to get it to the dealer for service. With respect, I doubt very much my local dealer will be opening it up at all and will say it has to go off to the factory. From what I can see by searching through others' experiences, this is likely to be a $800-1500 round trip, which isn't an option considering the low value of my back - an Aptus 54s.
So - has anyone changed the internal battery in an Aptus before or seen it whilst opening it up for any other reasons? I have all the screwdrivers - just no clean room!
Thanks and happy new year
