Review on 2 Pack Rechargeable LED Flashlight High Lumens with Included Battery - Waterproof, Zoomable, 3000 🔦 High Lumen Tactical Flashlights, COB Work Light with Power Display, 5 Light Modes for Camping Hiking by Tyrazz Abouzar

I like these flashlights but the batteries that come with them suck. If they were real 1200mah batteries they might be worth keeping, but both are poorly tested: one rated at 822mah, the other at 875mah (left two batteries in charger). 2500mAh (tested on 2487). The blue cell is a different cell from a cheap flashlight I just bought (ignore it). 14500 cells, AA Li-ion battery can hold 800mAh. While the best 18650 can hold 3500mAh. That being said, do yourself a favor, find a better battery, and you could triple or quadruple the battery life of this flashlight.
