For Efest LUC Charger Owners

[StormFinch]

I just found a new review of the Efest LUC charger over on the Candlepower forums. From what I can tell, the reviewer is very thorough and has posted quite a few well received reviews. According to his testing, the Efest charger he was sent was overcharging unprotected batteries and tripping the protection circuit on those that had them. If you own an Efest LUC, please be aware of this and check your batteries with a quality meter before using them. Also per the reviewer's info, the Efest's own voltmeter only goes to 4.2, so if your battery has been charged to 4.28 the charger will not register it or may register it as 0.0.

The review can be found here: Test/Review of Charger Efest LUC V4

I saw that review right after getting home from purchasing the LUC V4 on Friday (and posted my thoughts in that thread). My batteries are coming out at 4.20 volts on the nose (well, 12 hours after charging anyway). It seems my Xtar WP2 II was overcharging.

Anyone buy one of these from Eztechproducts on ebay? Just trying to work out whether his are the revised versions

I very recently saw a follow-up review of the LUC that said the revised version of the charger has fixed all of the overcharging issues.

Chargers and batteries shouldn't get second chances.

Which one is the latest vers? The orange screen/black text or Blackscreen/Red text

Read about this a while back. Of course, after I got a LUC as a backup charger....

I've noticed it charges my 18490s and 18650s to 4.25v, while the 18350s come out at 4.20v.

Mine's on the way, the supplier said the batch was purchased earlier this year so I'm hoping it will be the amended versions

I just got mine, and popped a battery into it, slot 4, it's saying it's at 4.2 volts, but it's still charging. This is the one with the red on black readouts. What does it do when it's done charging?

Yup, that's what it did alright. It does seem to be working as it should, and so far I like it, but then I just got it two hours ago. I'd rather the battery symbol turned green when it was done charging, but we can't have everything I guess. I'll just have to see how this charger works out over time.

I love mine, but it's not worth the risk to ignore the testing - guess I'll be verifying battery charges with the meter from now on

The only way you can confirm that is to check the battery voltage with a meter as soon as the charger indicates the cycle is complete. As was already mentioned the first generation LED display stops at 4.20 volts, even if the battery was charged to 4.28 volts.

Mine seems to be the second generation, but I am in fact checking the voltage after charging, and so far it's coming out right, no overcharging is seen. It's early on still, and my Nitecore i2 didn't show problems for several months. I'll continue double checking.
