I found the batteries that come with the Husky flashlights to not produce the best illumination for the flashlights (perhaps due to age or just a rapid decline in power while in use). I've gone and replaced them with Duracell rechargeable batteries, which ran me 22.99 for the 4 battery charger with (if I recall correctly) 4 AAA batteries and 2 AA batteries. I also purchased 2 packs of 4 AAA batteries for 13.99 each (this was from a local hardware store, so less expensive options are probably out there
. I'm constantly using 2 of the waylighter style sabers (1 waylighter and 1 Orion's Light) and have had no issues and allows me to have constantly fresh batteries.
