3.2.11 Battery Pack Maintenance
Over discharge, over charge and over current (short-circuit) are all
conditions detected by the internal “smart power gauge” of the battery.
These conditions all result in the battery shutdown (battery will not
deliver power) until placed into charge. Over discharge can cause cells
to outgas during subsequent charge cycles. Severe outgassing can
result in the battery pack swelling. Replace any battery pack with
visible signs of deformation or swelling.
It is important to understand the basic chemistry of lithium polymer
batteries. These batteries are a limited-life technology. The useful life
of the battery pack is affected by chemical processes which start the
day the each of the cells inside the battery pack are made. The life can
be further shortened by the way the cells are used and stored. These
cells will die faster if they are not held at some small level of charge
(50%) during non-use periods. If they are stored with any cell below
3.0V, a higher percentage of the cells will start to outgas and swell. If
they go to very low voltages, they may not charge well and make even
more gas.
The 1138 Operator’s Manual includes many cautions and suggestions
for caring for the battery. But lithium polymer batteries are sensitive
use and storage conditions, and inherently have a limited useful life.
From the chemical standpoint and normal distribution of failure, we
expect less than 5% should need replacement in less than 6 months. If
you see more than 10% of your batteries need replacement within 6
months of installation, we must look closely at the use and storage
conditions.
