Batteries Chargers
The FT-51R requires the FNB-38 9.6-volt re-
chargeable Ni-Cd battery pack for the full 5-watt
transmitter power output. However, where
slightly lower maximum power output is practi-
cal, the 7.2-volt FNB-35 (providing 4 watts) and
the 4.8-volt FNB-31 and FNB-33 Ni-Cd packs
(1.5 watts) offer smaller size, lighter weight or
extended battery charge life.
Also, when using the PA-1OA Mobile Power
Adapter, the Ni-Cd packs may be recharged
whenever the radio is inserted into the adapter.
Any Ni-Cd pack should be fully charged before
it is used with the transceiver for the first time.
Three types of battery chargers are available:
15-hour CA-9 Charging Stands, the NC-50 Dual-
Slot Rapid Charger (used with CA-10 Charger
Sleeves) and the internal charging circuit pro-
vided by the PA-1OAMobile Power Adapter and
an external DC voltage source.
Different 15-hour compact chargers are re-
quired for different packs (see table):

Ensure you use the correct charger for each

NC-50 Dual-Slot Rapid Charger
The NC-50 is a universal AC mains battery
charger with rapid and trickle charging modes,
and comes wired for the mains voltage in the
area sold. Up to two CA-10 Charger Sleeve units
fit into the base of the NC-50, allowing different
Yaesu Ni-Cd pack series to be charged.
The rapid mode initially brings the battery
pack to full charge as fast as safely possible using
a A-V sensor. A red LED lights during quick
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 battery in about 1 hour.
