Click to Enlarge Image
  • Nearly the same size as a AAA with 2-3 times the voltage, these cells power devices needing 3.7V like no others
  • Built-in PCB halts over-(dis)charge malfunctions in their tracks, keeping your medium-high voltage devices safe from harm
  • Li-ion chemistry provides more capacity (600mAh) than most alkaline and NiMH cells, so your devices last longer before recharging
  • Pair a 3-year shelf life with low bulk prices, and you'll find no reason not to stock up and plan ahead

Had these before and they are great for high capacity drain items. Ordered 10 more and have not been disappointed. These are a little bit longer than regular AAA batteries and may not fit in every device, but if you can fit it and your device can handle it, these are great little batteries. Not really sure if they are 600 mAh, but they seem to last longer than any other 10440's that I have tried, and I have tried alot of different brands.

Don't believe the ratings

600mA? I don't think so. 330mA would be the more realistic rating. The *fire batteries seem to exaggerate their specifications but they do work most of the time. Time will tell how these batteries will perform as I do have a few that still perform after 5 years.
