Lately, it seems like my 18500 (18490) batteries I purchased with my Provari only last like 15 minutes. I then put them on my wf-188 charger and they charge back up in like 10 minutes. I don't get it. Is it just time to replace the 5 batteries I purchased with my Provari?
Yeah, maintenance is important - and it could be your charger, too. Check the battery voltage when they're fresh off the charger. It should be 4.2 volts.

Thanks! I actually use a wf-139 at work and its the same problem.
I read the other thread and decided to pick up 2 new springs. Also, I'm going to clean the ProVari with a q-tip and alcohol when I get home. Hopefully, this works.
I'm just glad to know I'm not the only one with this problem. Seems like an easy fix, though.
