[amsat-bb] Batteries for FT 817

I use 2 FT817s for portable ops, and have been disappointed in the battery performance. Last year, I bought replacement batteries from Batteries America, the FNB-72xe, rated at 9.6v. at 2000mAh. There's no noticable difference between these new batteries and the originals.

The batteries charge to just over 11.0 volts, but quickly drop through 10 volts, as indicated by the voltage reading that appears when the rigs are turned on. Maybe this is just normal behavior for a 9.6 v. battery. Is this what you would expect? Has anyone found a battery with a higher voltage rating and/or one that will maintain a higher voltage for an appreciable period--and fits into the 817? Every bit of power helps!

Many tnx and 73, Tony, N2UN LM 183
