These are Ni-MH batteries. They work as advertised.
If you slow charge them you get more cycles.
Note that the advertisement says "upto 1000 times"

I bought an overnight charger and four 1800 milliamp hour AA's from Big
Lots for $10

I keep these in a Pro-95 (which like your 64 has a charging circuit)

I just bought a second set of DURACELL NiMH AA'S (2000 Milliamp hours) at
Wal-Mart for my yaesu vr-500 also for approximately $10.

They last like an alkaline with out the down sides of Nicads.

My Pro 64 takes four AA's and :-/...

..."each one charges up to 1000 times!"
..."charge in just 15 minutes using a RadioShack I-C3 charger!"
..."last up to 4x longer in your digital camera than regular alkaline
batteries."


Has anyone around here given these a fair trial, should we rush out to
buy, or instead to string up the RS ad writer?
