This is a brand new set consisting of one 3.7 volt, 800mAh 14500 rechargeable lithium ion battery and a digital electronic charger with automatic overcharge protection and LED indicator lights.  Just drop in battery and plug into the wall and the red LED tells you that the battery is charging.  When the green LED comes on, you are fully charged.  You can leave it plugged in, and the charger will automatically keep the battery refreshed and fully charged without any danger of overcharging.  Since this is a multi-charger, it charges all of the most commonly used rechargeable battery sizes and voltages:  AAA, AA, 14500, 18650, 16340, C, D, and 9 volt.

This is the absolute best 14500 battery you can get!   There are a lot of batteries being sold out there, but most are actually between 500 - 750 mAh, notwithstanding their lables often claiming much higher capacity.  We offer only 800 mAh 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 3.7 volt batteries, which make your high tech LED flashlight run much brighter than the ordinary 1.5 volts you get in a household AA battery.  Do a comparison yourself and you will see - these batteries get you maximum performance out of your flashlight or electronic device.   

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 from New Jersey via USPS mail, you get your batteries in a couple days instead of a few weeks if you were to order yourself from Hong Kong or Mainland China.
