You would think for the price and doing business it would have come with a case to hold it.
Battery arrived quickly. My 3 year old Fenix PD36R now functions like new.
great battery provides fantastic lighting. Great like ALL FENIX PRODUCTS !
Great to have a backup battery on hunting trips. Usual Fenix quality makes this a reliable addition to my gear
This battery lasts for ever. I use it in my Fenix PD36R Pro for work. Both are excellent buys. Would highly recommend
