So, I goofed last time I bought a battery charger and I bought one that only handles AA/AAA nimh batteries. Should have spent a little more and gotten one that can do Li-Ion 18650/14500 batteries as well. Anyway, I don't mind spending a little bit more for a good one that can display various values (voltage, capacity, etc.), has decent charging rates, and can discharge/test/refresh batteries as well. Currently looking at this Opus one, as I've been very happy with their nimh charger so far: http://a.co/3LBHotK It sometimes goes on sale for about $32. Thoughts? Other ideas/suggestions? Thanks!

I'm not an expert, or hardcore flashlight/torch/vape aficionado, so this is just my opinion and experience. I've been using a hobby/RC type charger for my 18650 cells for a long time. I use this: https://www.amazon.com/Genuine-SKYRC-Pow...ds=lipo+charger I started off needing to charge and balance multi cell RC battery packs before getting into 18650 powered flashlights. I ended up getting one of those 4 cell 18650 battery holders so I could balance charge up to 4 cells at a time. I liked that I could select the charge voltage to limit to 4.1V instead of 4.2V to increase cell life. I feel it's a good compromise of reasonable capacity for standby emergency use. If I'm going camping, I'll top it off to 4.2V before I go. I'm sure you've spent some time googling and reading about batteries already, but here's the article I base my procedure off of: http://batteryuniversity.com/learn/article/how_to_prolong_lithium_based_batteries The RC based charger has the benefits of being able to charge basically ever battery chemistry. As a side note, my Lenovo laptop also has an option to limit top charge percentage, so I don't let it charge above 80% unless I'm about to travel and want the max capacity (the battery is 4 years old now and still has 90.5% of original capacity). I have zero experience with those plug in chargers, just wanted to share my story smile

I've been using a WF-139 for about 7 years now. Of course, its used very infrequently. That said, it has always worked fine.

Thanks. I did look at this one. The main thing that worried me was the low charging current. Does it take a really long time to charge 3400 mAh 18650 batteries? Also, it doesn't seem to have a discharge function which I was hoping to get, but that's not that critical, I guess.

If the batteries are fully run down, then it will take a while. I usually charge them when they are half down. But you are right. Having 1A chage ability would be nice. I think you should go for it; it definitely has more features than the Nitecore. The specs and youtube video for the one you are looking at looks good.

I have the Nitecore D2 charger and it's a good charger, but I like the QTAR 4 position better: https://www.amazon.com/XTAR-Battery-Char...battery+charger It charges pretty much everything and provides good info on the status. It will do 1 amp if you use only 2 positions, but drops to 0.5 amp if you use all 4 positions.

the liitokala lii500 can be had for $15. look at budgetlightforum.com for the latest links. good low cost analyzing charger. my favorite general use charger is 8 bay it even does my 8ah nimh d cells. 8 18650 at once or 6 26650. mountain electronics is a class act too. no fakes or junk like ebay or amazon.

Yes, but no power supply included at that price, at least based on the current deals out there. Anyway, I ordered one to try. Apparently it's pretty good for Li-Ion batteries. Less good for NiMh, but I've got my other Opus charger for that.
