Safety Precautions
The West Mountain Radio CBA family of battery testers are inherently safe, but the batteries being tested are
not. Any system that stores energy is potentially dangerous. Some types of batteries are safer than others, but
all are capable of causing explosions or fires.
For technical information on a specific battery, refer to the Battery Manufacturers website. Most battery
labels have limited information, but the manufacturer’s website usually includes more detailed technical
information. General information for batteries is also available on the West Mountain Radio CD. Select Battery
Information and FAQs.
Primary Safety Considerations:
•
Never discharge a battery at a higher discharge rate than it was designed for.
•
Never use a battery that has poorly insulated, frayed wiring, or exposed metal parts.
•
Never connect a battery with reverse polarity.
•
Never test a battery near flammable materials.
•
Never allow a battery to reach a temperature that is too hot to touch.
