Leica M240 battery prep question

[Huss]

The first time one uses it, can it be recharged without adverse long term effect before it is fully depleted? Or should it be fully discharged before recharging?

I don't think modern li-lion batteries suffer from memory effect in this way ... I never bothered with any particular procedure with mine when I got it.

Recharge before using. There is no memory effect, but Li-Ion batteries suffer a lot of wear and tear by deep-discharging them. Try to keep your M batteries in rotation such that as soon as you can, charge them to 100%.

Thanks for the tips!

I heard that the life of a li ion battery is optimised if cycled between 25% to 85% (approx). Deep discharge is life limiting, as is continuous charging when using a laptop. I understand a camera is different, and I suspect the battery management turns the load off preventing a completely flat battery. Its usual for battery chargers to be 'intelligent' in that they prevent over charging. Regarding new batteries out of the box (and who knows how long it's been on the shelf), they are normally 50% charged on most products ive read about, that's to protect the battery. Charging prior to first use sounds like a good idea, and is not detrimental.

I have charged them before completely depleted many times. They seem to work just fine. No memory issues that I can detect. And BTW, the battery life of the M240 is really good 🙂

You are not supposed to force-discharge Li-Ion batteries, except to recalibrate the camera readout if needed. Ignore the instuctions to discharge completely in the manual. Using the camera normally suffices.
