3.2.1.2 Battery Charging
The 4380 battery can be charged to capacity in 5 hours using the provided battery charger (see Figure
A-3 ). The external ON/OFF switch must be in the on direction to charge. Charge status and battery voltage
can be monitored via the serial port or by looking at the two LED charge status indicators on the beacon
PCB.
WARNING!
Whenever charging the batteries, remove the Kynar closure strip and
purge plug. If any venting should occur, the end cap will push back,
allowing the venting to occur harmlessly. Be sure to reinstall the Kynar
closure strip and the purge plug prior to deployment.
Lithium ION batteries cannot be charged when the temperature inside the beacon housing is below 0
degrees or above 45 degrees Celsius. The beacon’s charge management circuitry monitors the
temperature inside the housing, and will halt charging if the temperature is outside the allowable
temperature range. Charge status can be monitored via the serial port. The charge circuitry requires an
absolute minimum input voltage of 22Vdc to operate. A continuous 5 hour charge will restore batteries
to full capacity.
The Lithium ION battery packs used in the 4380 beacons have an integrated battery protection PCB in
them. This protection circuit prevents over charge and over discharge.
Spare or replacement battery packs are available from EdgeTech if necessary. A properly maintained Li-
ION battery will provide several hundred charge/discharge cycles before replacement is necessary.
3.2.2 Activation
The 4380 series beacons are activated by rotating the external on off switch, located on the lower end
cap, to the ON position. Switch positions are defined as: OFF being when the white dot on the rotary
switch is adjacent to the pressure port, ON is when the white dot is rotated 180 degrees from OFF.
Approximately 1 ½ seconds after the switch is turned to the ON position the beacon will emit a single
power-up ping.
During deployment, if the beacon begins to miss interrogation pings, in an alternating manner, the
batteries are running low.
