Table 3-15 Operational Problems - Battery, AC or DC Power Modules, Battery Charger Adapter
Symptom
Low battery life (depletes quickly in
use).
Charging indicator doesn't come on
when Power Module plugged into
Battery Charger Adapter or into
M3500B/M5500B.
Fails Battery Capacity Test
Done indicator doesn't come on
even after plenty of charging time
(>14.5 hours).
"Unsupported Battery" message
appears on the screen
M3500B/M5500B Service Manual
Battery and Power Modules
The following table covers problems that might arise with the Battery or
Power Module. Refer to Figure 3-3 to identify the indicators. Refer to Table 3-
16 for the different combinations of indicator illuminations.
Possible Causes
Very frequent use - not charging
long enough between uses.
Battery failure.
Power module failure.
Failure on Control PCA, Power
PCA, or Battery PCA.
Power module failure.
Battery old, worn out, or failed.
Failure on Control PCA.
Performing System/Shift Test resets
the Power Module's charging clock -
thus "Done" never illuminates even
though battery is charged.
Battery failure.
Power Module failure.
• Not an M3516A battery.
• Battery damage.
• Failure on battery PCA.
Operational Problems
Suggested solution
Charge fully between uses. Use
spare batteries and adapters as
needed to allow complete charging.
Run Battery Capacity Test (see
"Battery Capacity Test" on page 2-
31). If battery fails test, replace bat-
tery.
Replace Power Module.
Replace 1) Control PCA 2) Power
PCA 3) Battery PCA.
Replace Power Module.
Replace battery.
Replace Control PCA.
Use spare batteries and adapters as
needed to allow complete charging.
Run Battery Capacity Test (see
"Battery Capacity Test" on page 2-
31). If battery fails test, replace bat-
tery.
Replace Power Module.
• Use an M3516A battery only.
• Replace the battery.
• Replace the Battery PCA.
