This is a set consisting of two (2) MonsterFlashlight.com brand 3.7v, 800mAh 14500 rechargeable lithium ion batteries and a dual digital electronic multi-charger with automatic overcharge protection and an LED indicator light.  Just drop in one or two batteries and plug into the wall.  The red LED will tell you that your batter(ies) are charging.  When the green LED comes on, you are fully charged.  You can leave it plugged in, and the charger will automatically keep one or two batteries refreshed and fully charged without any danger of overcharging.  This charger will charge 14500 batteries as well as 18650 and 32600 sized batteries.

There are a lot of batteries being sold out there, but most are actually between 500 – 750mAh, notwithstanding their labels often claiming much higher capacity.  We offer only 800mAh 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 3.7 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.  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 compact MF Tactical flashlight on the best possible battery to get the most out of your light.  Since we control the battery making, we can insure that you get the best possible rechargeable battery at the lowest possible price.
