"Strong, long lasting and built tough. Only kind I buy."
"yes these are the best headlight batteries"
"I purchased two more batteries to have for backups to use with my new Fenix TK28R that I recently purchased. The Light is Great and the Batteries Last for a long time but I bought a couple more to have on Standby."
"This battery is compatible with a flash light I inherited from my father. Works good!"
"Do to how this batteries are presented, I was under the assumption I was purchasing batteries in pairs, not singles. Thought I was clearly ordering 10 batteries. Only recieved 5. With this knowledge and hindsight being 20/20 I looked at the order confirmation and now understand that I bought only 5. I feel decieved by this marketing ploy. Hopefully, others will read this before purchase and not be duped into thinking they are buying batteries in pairs of 2."
"Great product always like to carry a spare poweer supply and this fits the bill"
"Very good battery. Lasts for along time before needing charged."
"I'm always looking for the highest capacity batteries I can find for use in my Fenix flashlights. This 4000 mAH battery has 14% higher capacity than the next smallest L18 battery from Fenix, which is the 3500 mAH battery. Higher capacity means longer battery life and less frequent charging."
"Always a great, everything this company makes is solid and well built."
"Reliable battery"
