4.8 BATTERY ENVIRONMENT
Batteries should be stored and installed in a clean, cool and dry place, keeping water, oil and dirt away from
the batteries. If any of these materials are allowed to accumulate on the batteries, tracking and current leakage
can occur, resulting in self-discharge and possible short-circuits. Battery chargers should also be installed in
well-ventilated, clean areas that are easily accessible. Relative humidity should be <90%.
4.9 TEMPERATURE
The operating temperature range for discharging TR GC2-48-G batteries is -4°F to 140°F (-20°C to 60°C).
Charging batteries below 32°F (0°C) is prohibited, and charging currents must be reduced below 68°F (20°C).
See the product datasheet for more information on charging current constraints.
Note that battery life diminishes as temperature increases, while capacity diminishes as temperature decreases.
It is important to minimize temperature variations between the batteries. Therefore, avoid restricting airflow by tightly
packing batteries together. The batteries should have a minimum of 0.50” (12.7mm) of space between them to allow
for adequate airflow.
4.10 BATTERY STARTUP
Your battery may be shipped at 50% state of charge or lower. Prior to installation, follow the instructions in
Section 6.2: “Initial Charging.”
Perform the following steps to turn the battery on:
Verify that the battery is either completely disconnected or correctly connected to the equipment it will be powering.
î Be sure that you are able to see the LEDs, then press and hold the status button.
î The LEDs will successively turn on from left to right until they are all on.
î Once all LEDs are on, wait another 2 seconds, then release the status button.
î The battery will perform a self test for about 10 seconds and turn on. Press and release the status button
to verify the green LED is on and the battery is ready to be used.
Perform the following steps to turn the battery off and place it in storage mode:
î Press and hold the status button.
î All LEDs will turn on, then successively turn off, starting with the green LED.
î Once all LEDs are off, wait another 2 seconds, then release the status button.
If the battery has been intentionally turned off for shipping or because of a shutoff condition, you can restart it by the
above steps. However, if a condition that causes a shutoff has not been corrected, the battery will shut off again.
See Section 10.3: “Protection Limits: Automatic Safety Shutdown”, for specific explanations of shutdown causes.
