Good but Bad

I love my Fenix Flashlight when it works correctly. I’ve had it about 2 years and use it strictly for deer hunting purposes! The battery ran down and I tried to recharge it , to no avail! So I figured the battery or charger either one could be bad! So I ordered a new battery and charged it when I received it. Which cost me around $30, and it worked fine! I had only recharged the original battery one time and the battery was bad! Glad I found out what the problem was is the good part, as well as the service getting the new battery to me, the bad part is I bought a high dollar flashlight with rechargeable batteries and after 1 charge it was bad so why buy rechargeable batteries ifIm gonna have to buy a new battery after 1 charge ! I think Fenix should have replaced the battery at no charge, that’s the bad

Hi Dan - did you contact warranty about the defective battery? The only order we are finding under your email address is the recent battery order, and our warranty department isn't finding anything from you. Thus we are wondering if the light was purchased elsewhere, and you talked to a different warranty department about the battery. Generally our warranty department will take a look at everything and replace the battery if it is indeed a dud. If you did not contact the warranty department where you bought the light, I would definitely recommend doing that were you to ever have any issues in the future, which I certainly hope you don't. Our warranty rate is extremely low, so you should be set. Glad to hear this new battery is working great for you.

Another Fenix winner. This is a professional tool in a compact form. Tons of light and other features. I am a committee member for our local FIREWISE prevention efforts. This flashlight will be given away as a door prize at our upcoming event. The pitch is to have the PD40R V2, charger, and spare battery in your Bug Out kit.
