Just a side note, if you want the
flexibility of using external power with the rechargeable pack that comes with
the unit, not for recharging, but for saving the batteries, just place a piece
of take over the insulation that was removed from the bottom most
battery.? Then you can run your RT-60r from the accessory plug in your car
and save the batteries, to continue the QSO while waiting on line at Dunkin Dougnuts!?
Just remove the tape when you plug in the overnight charger.

Case Question
?
Dan and Group,
I talked to a Yaesu person a few days ago about
this subject.? He added the same caution as the notes that come with the
radio but also (off the record) told me that this is mainly for problems
which might occur that Yasue does not want to get involved with. Things
like law suits - I suppose! Most well designed battery's have a thermal
cut-out device in series with the cells and will disconnect the cells if the
current is excessive or the temperature of the cells is too great. Anyway, I carefully looked at the supplied battery
and, if you look at it carefully, you will notice that the
"end" AA cell - toward the bottom of the case, has the insulation removed from the
bottom end of the cell.? This makes a contact with the radio to charge the
cells.? If you want your rechargeable
cells to charge with the supplied wall-wart, then just remove the insulation from the bottom of the cell that is
in the bottom of the battery case. Presto the wall wart will now charge
the cells you have placed in the battery case. BE ADVISED!!!!DO NOT DO THIS WITH ALKALINE CELLS AS THEY WILL
EXPAND, AND EVEN CATCH FIRE.? ALSO I'M NOT SURE AS
TO THE CHARGE RATE BUT I WILL ASSUME THAT YOU CAN CHARGE THESE NEW "CHEAPIE"
NiMH 2000+ mAH CELLS THAT ARE ALL OVER THE PLACE, SINCE THE SUPPLIED CELLS ARE RATED
LOWER - AT 1400 mAH. Hope this helps, Tom - KI6O
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.
????????
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?
