Chapter 13 Battery Servicing

A pulse battery charger sends current into the battery in pulses of one-second cycles; used to recover ________ batteries.

• corroded

• frozen

• sulfated

• primary

A battery charger that varies its output according to the sensed condition of the battery it is charging.

• automatic

• pulse

• auto ranging

• self polarizing

A process that reduces the plate surface area and therefore reduces capacity. This may also produce short circuits between the bottom of positive and negative plates.

• shorted

• sulfated

• shedding

• flaking

A test that indicates how charged or discharged a battery is, not how much capacity it has.

• capacitance

• open circuit voltage

• internal resistance

• load

A device that clamps around a conductor to measure amperage flow. It is often used in conjunction with a digital volt-ohm meter (DVOM).

• current clamp

• voltage clamp

• Ohm clamp

• alternating clamp

A battery test that subjects the battery to a high rate of discharge, and the voltage is then measured after a set time to see how well the battery creates that current flow.

• capacitance test

• load test

• conductance test

• open circuit voltage test

A type of battery test that estimates the battery’s ability to conduct current.

• conductance test

• open circuit voltage test

• load test

• capacitance test

A weakened battery can cause ____________ to have a shorter life.

• battery terminals

• an alternator

• light bulbs

• Starter drives

An explosive gas consisting of ___________ and oxygen is produced from charging and discharging batteries.

• helium

• hydrogen

• nitrogen

• ammonia

A load test is based on the ________ of the battery.

• cranking amps

• cold cranking amps

• open circuit voltage test

• reserve capacity
