"Bought extra battery cause I use one a lot at night and just wanted just in case!"
"Good product. Works well. Shipping was a problem as it took 4 weeks to receive, but it was fault of USPS and not Fenix."
"No issues in the first two weeks at least"
"This battery charges quickly. Works flawlessly in my flashlight. Lasts along time between charges."
"Battery came at half charge, charged to 100% but capacity was no where near 3400mAh on a meter. I had to use a charger that has a drain feature to take it to almost 0%. Once I charged it from there, everything is running and displays at full capacity."
"This flashlight is basically just an over-priced, not near as good as advertised flashlight. It goes thru batteries way too quickly, and takes forever to charge. Many times the light wont show green, for a full charge, unless you unplug it, and then plug it back in. All-in-all… Not worth the money."
"I may be Fenix superfan biased, but everything that Fenix makes is top-notch! I'm proud to be a part of the Fenix Lighting family!"
"This battery has a lot of positives. It holds a charge well. Size is comfortable for every day carry. Price was very reasonable. provides a very strong beam"
"Great battery run time and holds charge well but best thing is dont need to go store to keep buying battery. Very good product"
"Battery hold it's charge through long projects. Quick recharge. That all for now. g"
