9 Troubleshooting
The smart batteries provide greater useful life than comparable lead-acid batteries. Despite the
high reliability of the smart batteries, you may encounter situations where the battery does not
operate as expected. These situations are typically the result of misuse, abuse or a non-optimal
operating or storage environment. This chapter details potential issues you may encounter with
the smart batteries and the appropriate troubleshooting procedures.
9.1 Charger Trips using Constant Voltage
Problem
:
CV charger trips when charging the smart battery. This is due to the low impedance of
the battery creating a current inrush.
Solution: Reset the charger and try again.
9.2 Terminal Voltage Absent or Low
Problem: Using a multi-meter to check terminal voltage shows the terminal voltage is low.
Possible causes for this problem are:
Blown fuse
The voltage of a cellblock within the battery dropped below 2.4V, causing the microprocessor
to enable under-voltage protection.
The battery’s SOC dropped below 5% from either an extended idle period or heavy use,
enabling under-voltage protection.
The battery overheated, causing the microprocessor to enable over-temperature protection.
Solution: To resolve situations where terminal voltage is absent or low:
1.Allow the battery to cool and then re-check terminal voltage.
2.Inspect the fuse and replace it if necessary. Use only fuses that meet the specifications
