Question: Does the charger turn green when the batteries are fully charged?
Document: Those are the colors the charger displays - green when you first put the batteries in the charger to be charger; Orange (or some redish tinge) when you plug the charger into the outlet; and green again when it appears to be fully charged. Works very well with the Ultrafire flashlight.
Purchased 2 of the lith battery and charger. pricing was excellent. tested items on a TK-75 Fenix flashlight with a 2,600 lumen output and worked well. didn't know that once battery is installed in the recharger  a green light comes on it doen't tell if the battery is fully charged? The green light disappears after leaving battery in charger for several hours. This should come with instructions about light on the re-charger. Green meaning its not fully charged it is reverse.
The batteries tell you on the label if they are protected , if not the charger will turn green to show a full charge. Great deal.
I held back one star because I like a lot of people have become spoiled by fast charging lithium batteries and this is an overnight charger so know that going in. I have just bought another and more batteries too and can charge 4 at a time now and stay ahead of my needs. Works great and the led light turns green when both batteries are fully charger.
the batteries are fine. the charger has a light the when you put the batter in lights up green when unplugged if the battery is charged. but when you plug it in to charge the battery, the light turns red and stays that way. kinda cockeyed if you ask me. but all works fine.
Unpacked them, plugged the batteries into the charger and then plugged in an outlet and in a few hours they were fully charged.
Just a basic charger. Plug is built in which is good or bad depending upon where you normally plug in your chargers. Red light when the batteries are charging and green when they are charged I guess. Does not seem to be poorly made nor does it look like top quality. So four stars because it is neither great nor garbage. I have no idea how long it will last but on its first use I have no indication that it would break easily.
The batteries that come in this set are fantastic but the charger is junk. Batteries charge in an hour or so in my light but when using this wall charger they take the better part of 2 days and still don't seem fully charged
My new flashlight takes this "new" 18650 battery... and this product - with two batteries plus a charger - is a very good deal.They came quickly and almost fully charged... and so much more easily than trying to find this size battery in our local store.
These came fully charged and so far have performed very well, will know more after multiple charge. Nice charger compact size.
