Note 2: This item is packaged and priced as one unit - one battery. 

Shipping Note: Lithium ion batteries are considered "dangerous goods" per US transportation regulations and can often only be transported via ground shipment. Orders containing loose batteries will typically take much longer than predicted to be delivered. Delivery times of 14+ days are not uncommon.

Great replacement

"I have an older, non-rechargeable PD35. My brother in law recently purchased a PD35 v. 3. 0 and I tried his rechargeable battery in my light and it worked perfectly. I purchased this battery and now I don’t have to purchase batteries! It also seems to be a little brighter."

Poor Customer Service

"I placed my order for a genuine fenix replacement battery (for my fenix headlamp) on 11/15/24. . . . . . . I have NOT Received it as of today 12/3/24. I have called fenix customer service and requested a refund and was told " to continue waiting for my order". . . . . . . meanwhile I am getting multiple emails every single day telling me how great fenix is and what orher great items I should purchase from them. This is insulting to me. I recommend that if you are thinking of purchasing anything from fenix you should BEWARE ! VERY DISSATISFIED CUSTOMER Nicholas V."
