Subject: [FT-60] Rechargeable NiMH AA's



When I purchased my FT-60, I also went for the FBA-25A AA battery
case. I threw in some older Energizer AA Alkalines to try it out and that
works fine. However, I was mildly surprised to read in the manual that
users were cautioned not to use rechargeable batteries in this pack because
it did not include the usual current and voltage limiting circuitry found
in their own rechargeable packs.

Now, I can understand the point of this admonition if all they
mean is not to recharge such batteries in the radio using the supplied
power supply. However, I can't see the risk in using batteries recharged
outside the radio on a free standing recharger. Am I missing something
about NiMH batteries here? Is there some risk in putting six previously
Energizer NiMH 2100 mAh cells in the unit? I can't imagine why there should
be, but Yaesu's directions seem pretty specific here. If the more
technically savvy amongst us can enlighten me, I'd appreciate the help.

[FJ>] You can put any type of batteries in there! I use RayoVac IC3 2000maH
batteries. The great thing about the FBA-25 is that when you apply external
power, the power connection between the batteries in the FBA-25 and the
radio is broken and the external power, powers the radio. Therefore, no
matter what type of batteries you put in the FBA-25, you are not charging
them by hooking up to an external power source! Of course, I take out my
IC3 batteries and charge them in the RayOVac supplied charger, which must
have some magic because they charge in 15 minutes! The overnight battery
charger is not intended to power the unit with the FBA-25 installed. One
caveate - just make certain, that the bottom most battery is not exposed to
the 'charge-point' located on the back (internal) of the radio. It is very
obvious if you look at the FNB-83 battery.

While we are at it, is there a drop in charger for the supplied
FNB-83 battery. I'm told that the CD-29B rapid battery charger is not yet
available. Is there an aftermarket drop-in charger that allows the FNB-83
to be charged (relatively quickly) outside the radio unit itself? I seen it
suggested in an e-ham review or two that the VX-150 accessories will work.
Is that correct as respects charging the FNB-83?

[FJ>] This I leave to Brad who posted some news today about the availability
of the drop-in charger and its proported ability to charge 3 technology
types.
