Batteries & Chargers
The FT-50R requires the FNB-41 or FNB-42 9.6~volt
rechargeable NiCd battery packs for full 5-watt
transmitter power output. However, where slightly
lower maximum power output is acceptable, the 6-
volt FNB-40 and -49 Ni-Cd packs offer smaller size
and lighter weight. Any NiCd pack should be fully
charged before it is used with the transceiver for the
first time.
Two types of battery chargers are available: the
NC-60 K-hour compact charger and the NC-50
Rapid Charger (used with CA-14 Charge Adapter).
The NC-60 is available with a “B” suffix for operation
from 117-V AC, or with a “C” suffix for operation from
220-234-V AC.
NC-50 Dual-Slot Rapid Charger
This AC mains battery charger features rapid and
trickle charging modes for all FNB Ni-Cd packs. It
requires the CA-14 Charger Sleeve for the FNB-40,
-41, -42, and FNB-49, and comes wired for the mains
voltage in the area sold.
The rapid mode automatically brings the battery pack
up to full charge as fast as safely possible using a
peak voltage sensor. A red LED lights during rapid
charging, and when the pack approaches full charge,
the charger reverts to trickle mode (green LED), to
prevent self-discharge. The rapid mode recharges a
fully-discharged battery in about one hour.
FBA-15 Dry-Cell Battery Case
The FBA-15 dry-cell battery case uses four “AA”-size
(UM-3) batteries. Maximum power output is about 2
watts VHF, 1.5 watts on UHF. Use alkaline cells for
best performance. For ease of battery installation,
insert the + end in first, then press the - end so that
the battery “snaps” into place. Note: the lower single
battery can be ejected by pulling upward on the thin
strip.
Caution! The FBA-15 must not be used with re-
chargeable cells. It lacks the necessary thermal and
over-current protection circuits provided in the FNB
series Ni-Cd Packs.
One or more of the above battery packs/cases may
be supplied with the transceiver. If you need a bat-
tery, contact your Yaesu dealer. We do not recom-
mend using any other type of battery, and doing so
may affect your warranty.
Battery Removal & Replacement
Make sure the power is switched off, and remove
the protective soft case, if used.
Hold the radio face down in your left hand, and with
your right hand, press the Battery Release button
behind the antenna jack while sliding the battery
down 1/4 inch. Then lift the battery away.
To open the FBA-15 battery case, hold it in your right
hand, inside up, and slide the release catch upward
while slipping your left index finger under the notch
to the left of the release catch to lift the panel. Always
