AA Rechargeable Duracell Battery Beware

[palmerjrusa]

In case anyone is wondering about using the newly available rechargeable lithium AA cells in a radio take note.
The voltage reduction circuitiry (3.7 to 1.5v) in the cells emits so much RF it all but obliterates reception in the MW and HF bands. I thought one of my pocket radios had started to malfunction until I realized what was going on. Confirmed this observation in a couple other radios. How far the batteries are from the "heart" of the radio or how the radio's circuitiry is shielded appears to determine the extent of the interference.

I second using Harbor Freight batteries, as I use them in my scanners and charge outside the radio. May not be the longest lasting, but get a long run time on them in the PRO-106.

Plus they easy to purchase locally and many times are on sale.

This results of this review of AAA cells are interesting:

The AllMax and Fuji Enviromax brands come out looking like very good value.
