Battery Pack Test (2523)

Battery Pack Test
  1.  Remove the battery pack.
  2.  Measure the voltage at the battery contacts as shown below.


Contacts Voltage (Vdc)
+ +9.0 to +12.6
- Ground

Use the following procedure to check if the thermal protection has tripped.
  1.  Measure the resistance with an ohmmeter between the T  and - contacts.
  2.  The resistance should not be open (infinity).
     The thermal protection is detected when the temperature exceeds  70°C to 80°C (158°F to 176°F).  Wait until the battery temperature becomes normal, then  verify the resistance at the battery terminals. If it is open, replace  the battery.
