Charging Nickel-Cadmium
Battery Packs
Nickel-cadmium battery packs come
fully discharged. You can charge the
special-order batteries while they are
in the battery compartment using an
AC adapter (such as Cat. No. 273-
1664, not supplied) or DC adapter
(such as Cat. No. 273-1801, not sup-
plied).
Warnin
g
:
Do not try to charge non-
rechargeable batteries. The batteries
can become very hot and possibly ex-
plode.
Follow these steps to recharge nickel-
cadmium battery packs while they are
in the battery compartment.
1. Connect an AC or DC adapter.
See “Using AC Power” on Page 7
or “Using Vehicle Battery Power”
on Page 8.
Notes:
• It takes about 15 hours to
charge fully discharged nickel-
cadmium batteries.
• You can play a CD while
recharging the batteries; how-
ever, this could cause the bat-
teries to recharge more slowly.
2. When the nickel-cadmium battery
packs fully charge, unplug the
adapter from the AC outlet or cig-
arette lighter socket, then discon-
nect the adapter from the CD
player.
Charging Tips
• Always keep the charging termi-
nals clean. Use a cotton swab
dipped in alcohol to clean the ter-
minals.
• Under normal usage conditions,
the nickel-cadmium battery packs
can be recharged about 500
times.
• Fully discharge the battery packs
occasionally by playing the CD
player until it no longer plays.
Then fully recharge the battery
packs. This helps restore the bat-
tery packs’ full charging capacity.
• Avoid charging the batteries in a
hot environment (more than
113°F) as this can permanently
reduce the battery packs’ charg-
ing capacity.
• Do not overcharge the battery
packs. Overcharging can severely
reduce the battery packs’ useful
life.
• Do not short-circuit the battery
packs’ terminals (+ and –).
