CHAP 51 Verified A+
Technician A says that distilled or clean drinking water should be added to a battery when the
electrolyte level is low. Technician B says that fresh electrolyte (solution of acid and water) should be
added. Which technician is correct? ✔️Technician A only *
All batteries should be in a secure bracket that is bolted to the vehicle to prevent physical damage to the
battery ✔️True *
A battery date code sticker indicates D6. What does this mean? ✔️The date it was shipped from the
factory was April, 2006. *
Many vehicle manufacturers recommend that a special electrical connector be installed between the
battery and the battery cable when testing for ________ ✔️Battery drain (parasitic drain) *
When load testing a battery, which battery rating is often used to determine how much load to apply to
the battery? ✔️CCA
When measuring the specific gravity of the electrolyte, the maximum allowable difference between the
highest and lowest hydrometer readings is ________. ✔️0.050
A battery high-rate discharge (load capacity) test is being performed on a 12-volt battery. Technician A
says that a good battery should have a voltage reading of higher than 9.6 volts while under load at the
end of the 15-second test. Technician B says that the battery should be discharged (loaded) to twice its
CCA rating. Which technician is correct? ✔️Technician A only *
When charging a maintenance-free (lead-calcium) battery, ________. ✔️a. The initial charging rate
should be about 35 amperes for 30 minutes. b. The battery may not accept a charge for several hours,
yet still be a good (serviceable) battery. c. The battery temperature should not exceed 125ºF (hot to the
touch) d. All of the above are correct *
Normal battery drain (parasitic drain) in a vehicle with many computer and electronic circuits is ✔️20
to 30 milliamperes *
