Using Rechargeable Batteries

You can also use four rechargeable batteries. Before
you use nickel-cadmium or nickel-metal hydride batter-
ies, you must charge them .
The scanner has a built-in circuit that lets you recharge
Ni-Cd and Ni-MH batteries while they are in the scan-
ner. To charge the batteries, set
to
NI-CD NI-CD
connect an external AC or DC adapter to the scanner's
jack (see "Using AC Power" on Page 13 or "Us-
POWER
ing Vehicle Battery Power" on Page 14).
Warning: Do not connect either adapter to the scanner
if non-rechargeable batteries (such as alkaline batter-
ies) are installed in the scanner and
is set to
NI-CD
switch's position. Non-rechargeable batteries will get
hot and can even explode if you try to recharge them.
Before you use Ni-Cd or Ni-MH batteries for the first
time, charge them at least 24 hours to bring them to a
full charge.
Discharged batteries take about 10 to 18 hours to fully
recharge. If you use the scanner while the batteries are
charging, charging takes longer.
Notes:
• Nickel-cadmium batteries last longer and deliver
more power if you occasionally let them fully dis-
charge. To do this, simply use the scanner until it
beeps every 15 seconds and
• To prevent damage to nickel-cadmium batteries,
never charge them in an area where the tempera-
ture is above 113°F (40°C) or below 40°F (4°C).
