By interesting coincidence, the son of a friend of mine took second place
in a science fair by doing a study on battery life among different brands.

The executive summary is that all the batteries supplied about 3
Watt-hours, but the Energizers are 3x the cost of the no-name Rhino and
Tenergy batteries, about $0.20/Watt-hr vs. $0.08/Watt-hr. The Energizers
last about 15% longer, but that is not enough to offset the difference
in price.

I just took a minute to look for LR44's on eBay. They sell for like
$.10 each. I just paid $5 for one in the local CVS. I can't believe
that the name-brand batteries are really 50x better than the no-name
ones. I'll probably get gouged on the shipping, but it's still a
much better deal.

Beware of eBay cells.

I bought a couple sets for my welding hood.
They went flat very quickly. (They *were* cheep, though.)

Pre-discharging is just another service we offer!

The high-priced cells from my local pharmacy are still going strong.
