•RUSE INDOORS ONLY! NEVER expose the charger 
to rain, snow or any liquids.
•NEVER let metal, wire, etc. touch any internal part of 
the charger.
•NEVER incinerate used batteries. This may cause an 
explosion.
•NEVER use the charger when it is covered by objects 
which impede heat dispersal.
•Place the charger in a secure place to avoid inadvertent use by children.
•AVOID charging in extreme cold (under 0°C; +32°F) 
or extreme heat (over +45°C; +113°F). Batteries may 
not charge fully under extreme temperatures.
•Keep the charger away from TV sets or radios to prevent interference.
•RNEVER attempt to charge alkaline or dry cell bat- 
teries. They may burst causing damage and personal 
injury.
Make sure battery and charger contacts are always 
clean, otherwise batteries may not fully charge.
In order to get the maximum life out of your Ni-Cd batteries:
1. Avoid overcharging—batteries must be removed
from the BC-137 to stop charging. Batteries should 
not be charged for more than 15 hours.
2. Use the batteries until they become almost com-
pletely exhausted under normal conditions. 
If your batteries seem to have no capacity even after
being fully charged, completely discharge them, then 
fully charge them again. If they still do not retain a 
charge (or very little), new batteries must be purchased.
NOTE: When charging with a DC power supply 
(13.8 V) and the ambient temperature is near 0°C 
(+32°F), in some cases the charging LED may go 
out. This does not indicate a malfunction.
