LEDs

The LEDs indicate the charging status of batteries as described in the chart shown on the next page:
To remove a battery pack, push the locking tab down and pull the battery out from the charging pocket with a hinging motion.

Servicing The Battery Pack

To service battery packs, insert batteries into the charging pockets and press the Condition button. The Condition LED will flash
during the conditioning cycle. This starts an automatic process in which batteries are completely discharged and then recharged
to full capacity in eight hours. The Condition and Calibrate cycle resets and calibrates battery data so that the user gets longer,
more consistent performance from the batteries. HHP recommends that battery packs should be serviced, or calibrated, once a
month.
Because the Dolphin QuadCharger is accumulating battery pack information during the entire Condition and Calibrate cycle, it is
important not to remove the battery until the cycle has been completed and the Condition LED is no longer flashing. Batteries
inserted after the "Condition and Calibrate" switch has been depressed will receive a standard charge. The chart below describes
the Status LEDs during the Condition and Calibrate cycle:

Storing Batteries

To maintain top performance from batteries, follow the guidelines below when storing them:
Avoid storing batteries outside of the specified temperature range of -4 to 104° F (-20 to 40°C) or in extremely high humidity.
For prolonged storage, do not keep batteries stored in a charger that is connected to a power source.
During long-term storage, battery deactivation may tend to occur which may cause charging to stop early during recharging after
storage. This issue can be handled by charging and discharging the battery several times. Also, the first charging after prolonged
storage may yield a lower than normal capacity. While this will vary depending on the storage conditions, charging and
discharging the battery several times will almost completely restore capacity.
