18650 Rechargeable Battery 3600mAh Large Capacity 3.7Volt Flat Top 2 Pack Lithium Batteries for Flashlight Headlamp

Good battery but does not hold the charge as it's rated for

Bought 8 of these 18650 cells. Installed & charged out of box. Power levels were at 100% on charger, immediately dropped to 90% once disconnected & then drained to Zero % 4 times faster than the batteries I was replacing that are over 2 years old with hundreds of charge cycles on them already.. Avoid these batteries. They are cheap for a reason..

Bought this when my original batteries were not lasting as long. Unfortunately, these NEW, don't last as long as my old ones. Very disappointed, not a good replacement, discharged quickly
