Maintaining battery life and performance
With proper care and maintenance you will maintain the performance and life of the battery. It is
recommended that you:
Use only Tait chargers and batteries.
l
Do not expose a battery to very high or very low temperatures for extended periods of time. Doing so
l
will shorten the service life of the battery.
Very high: above 140°F (60°C)
Very low: less than –4°F (–20°C)
Charge the battery at a room temperature of between 50°F and 77°F (between 10°C and 25°C). This
l
temperature range is the optimal charging range.
Wipe excess moisture and dirt from the radio, radio contacts and battery contacts before charging the
l
battery.
Store batteries properly when not in use. See
l
Replace the battery every two to three years.
l
Discard and recycle batteries after five years.
l
Avoid fully discharging batteries as this reduces life span.
l
Storing batteries
When not in use for a month or more, batteries should be stored correctly to ensure they are as close as
possible to new (manufactured) condition when put into operation.
Remove the battery from the radio before storage.
l
Fully charge the battery if storing for less than one month.
l
Charge non-IS batteries to about 60% if storing for longer than one month.
l
IS batteries self-discharge faster than other batteries. IS batteries which are not in active use should
l
be fully charged when they reach a period of 14 weeks in storage. This should be repeated for each
subsequent 14-week period.
All other batteries which are not in active use should be fully charged when they reach a period of 24
l
weeks in storage. This should be repeated for each subsequent 24-week period.
Store in a cool dry place.
l
Any battery found to have fallen below 4.0V should be disposed of appropriately. An exception to this
l
is the T03-00011-EXXX battery, which should be discarded if the voltage has fallen below 5.2V.
Batteries that have been stored for any length of time must be charged before being used. See

Notice IATA rules state that Li-Ion cells must be offered for air transport at a state of charge (SoC) not
exceeding 30% of their rated design capacity.
