Sorry if this a duplicate post.....computer issues!
I am noticing that my TM26 is not charging its batteries beyond 4.07 volts even after display reads "charge finished/4.2 volts".I have tried charging with different sets of batteries with same results. The last set were Nitecore 2600's. The batteries were all at 3.7 volts (measured on a Fluke meter) before placing in flashlight. The display on the TM26 also showed a voltage of 3.75 volts (very accurate). During the charge cycle, the TM26 voltage display never exceeded 4.07 volts even after 6 hours of charge. After a few more hours the flashlight displayed "charge finished/4.2 volts". Immediately after unplugging charge cable, the OLED display showed 4.07 volts. Measured batteries on Fluke meter and confirmed that the TM26 is not bringing batteries above 4.07v. I removed batteries and charged them on my Nitecore Intellicharger I4 to 4.2 volts. Inserted the batteries in the flashlight and the display read 4.2 volts........soooo the display is accurate, but there is a problem with the internal charger in the TM26.:mad:
