MF Tactical brand 14500 3.7v, 1000mAh Rechargeable Li-Ion Battery for use in R5-350-1C+/3C+ and CSI models only.

SKU: 1x14500 Category:


This is a 3.7v, 1000mAh 14500 rechargeable lithium ion battery. At about the same size as a AA battery but with more than double the voltage, this is the absolute best battery you can get for your compact MF Tactical flashlight!  There are a lot of 14500 batteries being sold out there, but most are actually between 500 – 750 mAh, notwithstanding their labels often claiming much higher capacity.  We offer only 1000 mAh 14500 batteries because these are the highest capacity that can be actually produced in this size battery.  Since they hold the most power and therefore last much longer between recharges, fewer recharge cycles means longer battery life.  And don’t forget the importance of voltage:  these are 3.7v batteries, which make your high tech LED flashlight run much brighter than the ordinary 1.5v you get in a household AA battery.  Do a comparison yourself and you will see – these batteries get you the maximum runtime and performance out of your flashlight.  If you have read our web site or heard about us online, you know that we are flashlight freaks!  That’s why we have spent time researching the science of li-ion battery technology so that you can run your MF Tactical flashlight on the best possible battery to get the most out of your light.  Now that we control the battery making, we can insure that you get the best possible battery at the lowest possible price.  Plus, since we ship quickly from New Jersey, you get your batteries in a couple days instead of a few weeks if you were to order yourself from the distant shores of China.
