Spare 3400 mAh Battery

You asked for it, here it is. This is a spare battery for our flashlight. This 18650 is a 3400 mAh battery and has the built in fuse protection. This slightly more powerful battery does not make the light shine any brighter, but will give you about 10% more run time on all light settings.  When ordered with a flashlight, we insert the battery into the flashlight to reduce the cost of shipping.
