Battery charger

Has anyone had any recent experience with the cheap battery chargers in the UK? 

My Leica one appears to have died and I can't afford a replacement Leica one.

Nitecore do one for the M9. I don’t use that one but I do use their one for the Q and it’s so reliable (with battery state readouts) I use it in preference to the Leica device.

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

Thanks for the information, however, the problem I have with the Nitecore is that it's a USB charger, I'd prefer a mains one.

I'm curious - why? I have a Nitecore one and it works well (for CL) - including from a USB mains adapter (Amazon Kindle, phone charger.......).

I'll look into that when I get over Christmas.  

Have a great festivities everyone.

You're in a great location!  Few years since I was down that way - still need to go back, again.

Then plug it into a "decent" mains USB supply, not a cheap Chinese one.  Has the advantage you can use the Nitecore in a car with a 12V adaptor and the possibility of plugging into a computer...

It probably doesn't help but either the M9 or M8 Leica charger should work. You can always try to find one used somewhere. Both chargers are radically different in look but they both charge the same battery types.

Thanks for the information everyone. I'll see what the finances are like when I get back after Christmas.

Well, I managed to get the Nitecore charger and get it working. However, when I put the own brand Leica battery into it to charge after a few minutes of charging it showed End so I took the battery out and put it into the M9 and had a look at the charge and it showed just over 75%. I repeated this with an OEM battery with the same results, except this showed below 75%. 

So, I returned to the original Leica battery charger and put both the batteries in. They showed the flashing light for a few minutes then a constant green. Back in the M9 and this showed no change from above. 

Any suggestions as to the cause of this and ideas what I do next? 

Happy New Year to all

Hello, both the battery and the charger seem to be fine. (If there are no other indications of an incorrect operation.)

Simply use the batteries periodically.

Here is some information about battery management:

A deeper understanding of the battery management gives the application note AN131.

Batteries do lose stamina after a while. A bit like me.
