How long does it take to charge 18650's?

Don't have the charger, but from the specs it'll charge 1 or 2 (at the same time) @ 0.75a and 3 or 4 (at the same time) @ 0.357, so for a battery with 2500mah capacity id expect around 3.3 hours to charge 1-2 batts or 7 hours for 3-4*

If you only need specifically a 18650 charger then the um4 model charges at twice the speed of the d4 and is listed at a cheaper price, but its currently out of stock.

link to um4 in case you want to set up an email alert for new stock

*not a mathemagian, so take my estimates with a grain of salt

I bought that one. https://s.click.aliexpress.com/e/cFuns7rZD



Looks like link is not working.
Ive got a couple of nitecore changers and both seem to have a problem charging AAA cells...they seem to sit too low and dont make contact with the metal spring clips and therefore wont charge.

Workaround is to slightly lift then up but its fiddly...anyone else have this issue?
