CHARGING THE Q3 BATTERY

Charge trough usb-c problem solved

Depends how good you want to be with your battery. Its the same when you charge your e-car. It will play a role only in the long run. There is a reason why the charging unit levels down its charging capacity.

The Leica Q3 is available for pre-order at B&H Photo Video and Adorama

Your battery will degrade over time. Faster if you charge fast and slower if you charge slow. But eventually you will have to replace it.
 

The cost to replace your car-battery compared to the Q3 battery is a bit far fetched. The Q3 battery costs 3% of the cameras value. An e-car battery is probably more like 30-50% of the cars time value several years in once you have to replace that battery. So it makes more sense to take good care of that battery compared to the benefit of slowly charging your camera. A camera battery is a consumable wheras in a car it‘s a different thing imho.

The battery in the LaFerrari costs 120.000€ 😎

According to their website, to achieve maximum battery longevity, you should only charge the battery to 80%, not fully, and only run it down to 20%… This does obviously mean you don’t get so many shots, but as the batteries are so so so expensive, for me it’s worth trying… I need two batteries for a full day, but I’m sure depending on how the camera is configured, some people may use three batteries…. 

Would you be so kind as to share the link to the place on the Leica website where they discuss proper battery charging.  I am unable to find the information.  Thank you in advance for your consideration.

I find all this a bit of overblown agonizing. A battery is to be used and emptied and charged, a tool to enable to make photographs. So it is supposed to degrade? So what?  I have my M8 batteries from 2006 that still work adequately despite having. fed many  thousands of images. Work out the cost per image. Just use the things. Each single image that you take is worth more in the end.
If the charging is too slow for your needs buy more batteries. Too expensive? What did that camera cost again?  How few rolls of film can you print for the price of a battery?

Have to agree. If I expect to do a longer outing, I make sure 2 batteries are fully charged, which makes for a 0.4 charge of extra capacity compared to 2 batteries charged to only 80 %. I often do street photography and then the camera is essentially always-on and I always keep it connected with Bluetooth to the iPhone to enable geo-tagging. In other words, unfavourable conditions for battery life. In that scenario I have to switch batteries every 2 hours. I carry a power bank and a BC-SCL6 to recharge the spare battery if needed. Works for me.

I have looked on the website and in the user manuals and cannot find any advice to charge only to 80%. If someone can give the reference to this, I would also be grateful. I know from other sites that not charging a battery fully makes it last longer; but I have had Minolta and Canon batteries for many years and have always charged them to 100%. They hve not worn out yet as far as I can tell. Is there anything different about the Leica battery, other than its exceptionally high cost?

It may seem a bit harsh, but it is unwise to buy a camera system that stretches your financial perception to the point that it impedes your photography. If you have to undercharge your batteries to avoid financial loss in the future, if you have to worry that your camera might get a few scratches during use, if a shower impedes your creativity, you own tools that you perceive as to valuable to use.

It is probably a misinterpretation of some articles on battery capacity. All Li-Ion batteries may only be charged up to 80% of their nominal capacity for safety reasons and longevity. All charging systems do so. If you charge up to 80% again you are using 64% of the nominal capacity. And you cannot discharge  under 10% either as that will kill the battery. So it is automatically limited in that respect as well. 54%? A bit silly, really.

Interesting and this seems to be confirmed by specifications of some power banks, that state a capacity as well as a useable capacity. I've seen several that state e.g. 10 Ah of capacity and only ~ 6 Ah of useable capacity. My own measurements bear this out, a new Li-ion battery always has a capacity of at most 65 % of its stated capacity.

[jaapv]

Precisely. And then people want to charge up to just 80% again?

i charger 100%. and I replace by the second one when its empty , I works perfectly for me , on the long run i will maybe loose 30€   🙂 not a big deal
