    18650's Care and Maintenance

    I charged the questionable battery and one other at 0.5A today and the both had 4.20 V an hour after coming off the charger. Previously I had been charging at 1.0A but maybe I'll cut back to the 0.5A. Any problems with that? The questionable battery was at 4.10V before charging it today and I...

    18650's Care and Maintenance

    Thanks for the detailed reply. I have made notes so I don't have to keep asking. The battery was at 4.14v yesterday and is 4.12v this morning. I use the same DVM and the other batteries typically settle at 4.17-4.19 after several day days. I do notice the XTAR VP2 charger will occasionally...

    18650's Care and Maintenance

    I've tried various searches with little luck so I thought I would ask. I'll be sure and note the responses this time. 1- Seems like in one post someone mentioned a charged 18650 should hold a charge for at least a week before starting to drop. Is this right? 2- Why I ask is I have a ~5 month...

    Holster for FD41

    The holster that came with my Fenix FD41 is wearing out. The velcro is coming loose and it's starting to lose its fastening capability. Any suggestions for a replacement holster that is fastened /loosened multiple times almost daily? Thanks

    Leaking alkaline batteries

    I revived this thread again to ask about using other batteries in the package that appear to not be leaking. I have a pack of Rayovacs AAA dated Nov 2024 with some leakage in the bottom of the original packaging. It has been stored in the house the whole time so there have been no...

    Checking my DMM DC Voltage Accuracy

    Sorry to resurrect an old thread but it's relevant to what I'm needing to figure out. I've noticed my old Fluke 75 seems to be indicating about 0.02v low as compared to the xtar VP2 and a Home Depot cheap-o which seem to be in agreement. I was thinking of getting one of the VoltageStandard's...

    noob question about XTAR VP2 Charger and NCR18650GA protected batteries

    Every time I think I have this figured out it seems like another question comes along. After resting overnight, two new batteries I charged yesterday on my VP2 were indicating 4.17v and 4.18v today. Does that sound right or should they be 4.2v? I'm thinking I read that this is OK and more...

    noob question about XTAR VP2 Charger and NCR18650GA protected batteries

    Is that just to keep the contacts clean or is there something else? I guess if you get the green light just reload them and start again? Thanks!

    noob question about XTAR VP2 Charger and NCR18650GA protected batteries

    I used my VP2 for the first time today. As it was charging at an indicated 4.2v, I touched the battery to see how warm it was. The charger gave the green light and I figured it was just coincidence. Then I charged another battery and when I check to see how warm it was at the 4.2v charging it...

    Test/Review of Charger Fenix ARE-X1

    Just wondering about the slight differences in fully charged voltages between batteries. All mine are newly purchased Fenix 18650, 3500 mAh. Are these slight differences a function of the charger or the battery's manufacturing tolerances/composition, or perhaps both? Other than checking them...

    Li-ion Batteries and their Protected Circuits

    It's the new guy again. I found this thread and it helped. What happened is that our FD41 stopped working. Put in another battery and life was good. Unfortunately didn't try the "old battery" again. However, the "old battery" is actually a brand new Fenix 18650, 3500 mAh and this was its...

    Safe 18650 Voltages Under Load

    I have the FD41 using an 18650 battery. Noting it has auto reducing brightness I asked Fenix at what voltages these reductions occur. I was told the cutoff for High is around 3.2v, and Medium is around 2.75v. Since the voltage is being monitored with the flashlight energized, I believe I am...
