Question: Are these batteries protected?
Document: 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.
Batteries barely stay in charger. Very cheaply made.
Works well!! No complaints! Has a fast charge and is easy to get the batteries in and out of the charger!
Unpacked them, plugged the batteries into the charger and then plugged in an outlet and in a few hours they were fully charged.
It is a SIMPLE charger. A good deal. There have been a few claims that the batteries may be counterfeit?
does what it is to do charges the batteries right to where you want them to be takes some time left on for 12 hours and all is great
When you plug the charger into the wall with the batteries they fall out. There is nothing that holds them. Piece of chinese junk
No complaints as the product arrived when promised. Charged the batteries and a few hours later i have a working flashlight again!
I like have an extra battery on the charger at all times and these batteries seem to be working great
Havent had any issues or complaints. Batteries last a long time in all sorts of flashlights and lasers that i have.
Answer: yes
