Quality.

January 29, 2021

Have two. One came with the new Fenix LD30 LED flashlight I bought. I added a second battery as a back up. Both appear to have very high build quality and quickly took a full charge from my Nitecore D2 Digicharger. The primary battery in the LD30 has been running strong so far. No complaints.

Great feature for charging!

This makes life that much easier for charging. This is my spare and so far is working well. I will be able to provide better feedback on longevity once I have charged it many times. Appears very well made and I'm sure will be the great quality I expect from Fenix.

When deployed I can take one in the flashlight and 2 in a carrier for search and rescue after dark. Easy to recharge even in vehicle. LED on battery top let's you know when charge is complete.
