it's unfortunate that they stopped making these as it's the best plug in emergency light that I've found.

[@WardCo]

Yeah. I agree.

Nice Job Ward
I'm always replacing the cheap commercial version of emergency lights and exit lights you see in a big box stores. Remarkably they use Ni-MH batteries. The lights are under charge continuously like yours, the problem being nickel cadmium developing memory and thus may fail after a year. I should modify this charging circuit for Metal Hydride, but then there is a liability issue, so I'm stuck with the nickel cadmium. One can save a little money buying replacing AA cells and soldering them like you rather than buying the replacement battery packs.

[@WardCo]

Thanks Mack. Yeah, it's surprising how many places NiCads still turn up. I hate 'em.

Yo Ward, ETSAIRs claim huge mA-hrs but are testing out about 400 mA-hr on my tester. The 14500s ran about 270-350 mA-hr while claiming 2800 mA-hr. "Now you know."

[@WardCo]

Thank you, sir!
I ran similar tests about 2 years ago when I first got these, and I knew the numbers were bad, but I guess I didn't remember HOW bad! :) Sigh. I was a fool!!!
