Troubleshooting

The TI 12V/110 is an extremely reliable battery module that provides greater useful life than
comparable 12V/110 lead-acid batteries. Despite the high reliability of the TI 12V/110, you may
encounter situations where the battery module 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 12V/110 and the appropriate
troubleshooting procedures.

Charger Trips using Constant Voltage

Problem
CV charger trips when charging the TI 12V110. This is due to the low impedance of the module
creating a current inrush.
Solution
Reset the charger and try again.

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:
• The voltage of a cell within the module dropped below 2.3V, causing the microprocessor to
enable under-voltage protection.
• The module 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 recheck terminal voltage.
2. Connect the battery to a charger to wake the battery and recover terminal voltage. Depen-
ding on the module's voltage and state of balance it may take up to 48 hours to completely
charge and balance the module.
