Exam 17: Batteries: Theory, Diagnosis, and Service

At 0 degrees Fahrenheit, a battery can produce only 40 percent of the electric current that it is capable of producing at 80 degrees Fahrenheit.

Technician A says when battery cells are connected together in series, the amperage increases. Technician B says when battery cells are connected together in parallel, the voltage increases. Who is correct?

Technician A says a battery strap or carrier should be used whenever a battery is lifted. Technician B says when a battery is removed, the positive cable should be disconnected first. Who is correct?

Technician A says lead in the lead peroxide of the positive plates combines with sulfate to form lead sulfate as a battery discharges. Technician B says lead sulfate forms on the negative plates as a battery discharges. Who is correct?

A battery is an electrochemical device that converts chemical energy into electrical energy.

Battery corrosion is commonly caused by spilled water and electrolyte condensation from ____________________.

Describe the cold-cranking amps rating.

Technician A says the specific gravity of pure water is 10.00 at 80 degrees Fahrenheit (27 degrees Celsius). Technician B says the specific gravity of electrolyte in a fully charged battery is between 1.260 and 1.280 at 80 degrees Fahrenheit (27 degrees Celsius). Who is correct?

A(n)____________________ is used to test for parasitic draw.

Technician A says jump-starting a battery can damage electronic components. Technician B says a dead battery should be jump-started instead of recharged. Who is correct?

Describe the ampere-hour rating.

Battery ratings are being discussed. Technician A says the reserve capacity rating is a measure of the battery's ability to operate the lights and electrical system in the event of a generator failure. Technician B says the cold-cranking amps rating is a measure of the battery's ability to provide current for the starter. Who is correct?

Battery hold-downs reduce the amount of vibration and help increase the life of the battery.

____________________ water should be used to top off the cells of a battery with removable cell covers.

When load testing a battery, the load applied to the battery should be _____.

Vehicles equipped for cold climates may have a battery blanket or heater to keep the battery warm during extremely cold weather.

Technician A fast charges a sulfated battery then reinstalls it in the vehicle. Technician B trickle charges a sulfated battery over 24 hours before reinstalling it. Who is correct?

How do you remove the surface charge on a battery prior to open circuit voltage testing?

Technician A says jump-starting an engine can cause a battery to explode. Technician B says jump-starting can damage the car's electronics. Who is correct?

Water is never added to ____________________batteries.
