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,
Not sure about fitting in the FT817....But there are a lot of people over
here participating in "summits on the air" driving / walking / climbing to
the top of a peak and making some QSOs. The FT817 is very popular and they
all seem to be using 3 series Lithium polymer cells.
According to the hype, the lithium polymers weigh nothing hold nearly
infinate charge and finally discharge within a few seconds of the natural
lifespan of the operators radio.
Whatever the reality, they may be worth investigating.
