We've tested many and these are the best affordable rechargeable AAA batteries available. Plus we designed the custom "flowcell" covers to create a brighter looking battery with swooshes that line up with the dots on your flowlight! :)
These NiMH batteries are listed as 1000 mAh, the highest available in a AAA cell. We've tested them to actually provide an average of 900 mAh, unlike many that claim to provide 1000 mAh, but only put out 700-800 mAh. These batteries also handle multiple discharges well and have a long lifetime unlike many of the cheapest available rechargeable.
