M240 memory settings w/o battery?

[Huss]

While I really like my M240, I don't use it that often. Normally I take the batteries out of my cameras when I don't use them, to reduce risk of leakage etc. But those cameras tend to be old film jobs where there are no memory or programmed settings.
If I take the battery out of my M240, how long before it loses the settings I programmed into it? And... if I take the battery out for a while, would putting it back in (say after 2 weeks) reset the amount of time I can take it out again? Aaand, how long would the battery have to be put back in before I can take it out again?

Yes I know I should use it more, but my film cameras get in the way of that.
😱

p.s. I wrote this same question on FredMiranda about my D750. Same deal..

Battery leakage with a Li-Ion battery? Is there one single reported case in the last couple of years?

The settings (the four customizable profiles) can all be saved onto the SD card and easily transferred back onto a camera.

That's what i did when i updated the firmware last time.

No idea about the memory settings when battery is removed but the SD card saving the settings renders the question moot (a little)

You still have to set the time again manually.

The M typ 240/246/262 have an internal condenser acting as a battery to maintain charge while the battery is removed for charging. With the power switch on OFF, it takes about three-four days to become exhausted and cause the camera to reset when a battery is next inserted. At that point, if you've exported your user configurations, you set the time and date and reload your configuration settings from the card.

But when you exhaust the internal condenser, it takes about a week or two for the battery to recharge it, shortening battery charge cycles until it does so. So if you always remove the battery and exhaust the condenser, you'll forever have shorter than optimal battery life between recharges.

LiIon batteries don't leak, or do so at least extremely infrequently. I would only take batteries out of my cameras if I positively, absolutely knew that I would not be using them for three months or more at a stretch. There's really little point to doing so otherwise ... just check the battery condition every so often and charge it up if it's gotten down near 25%, and charge it up when you go to put a camera that's been sitting for a while back into regular service.
