The following table describes the display of LED lights at different stages of charging:
Q: Can I leave the battery continuously on the charger?
A: Yes, the charger will go into "maintenance mode" and keep the battery topped off.
Q: Can I draw power from the battery when the charger is connected?
A: Probably. . . There is some pulsing going on with the charger which your equipment might not be happy with (it is a pulse-charger, 1 second pulses with 20mS gaps), but if you combine this with the battery the battery will fill in the gaps, so the ripple is no more than it would see in an automotive application.
Q: If I discharge the battery while the charger is attached will the charger maintain a full charge?
A: Yes, When the charger detects that the battery voltage has dropped it knows that the battery needs to be charged and goes into "bulk charge" mode again automatically.
Q: Can the charger be left connected to the battery when the charger is not turned on, or when the input voltage of the charger has been cut off?
A: Yes.
  1. A qualified automotive electrical technician should be used to wire the charger into the vehicle.
  2. The PBCD305-12-12 converts 12 volt power into 12 volt power, so for a 7.5 amp output the input needs over 8.3 amps. Make sure that the wires connecting the PBCD60-12-12 are adequate for the current and the length of the run. If the voltage drop in the wires are too much the "Low Battery Voltage" alarm will come on. Wires that are too small may also overheat and melt the insulation, causing a dangerous situation. 12 gauge is usually adequate for runs up to 20 feet of wire (adding together the positive and negative wire lengths).
  3. It is OK to leave the unit on the charger when the power to the charger goes on and off.
  4. Mount the PBCD305-12-12 in an area that will get adequate ventilation and will be free from rain, spray, or excessive dust.

Applications:

OEM Battery Chargers Charging wheel chairs, bicycles, and scooters in a car, van or bus.

OEM Battery Chargers Fully automatic without intervention.

OEM Battery Chargers Output short circuit and battery polarity protections. Input low voltage and high voltage connections.

OEM Battery Chargers Charging 12 volt batteries from a vehicle.

OEM Battery Chargers Charging 12 volt "jump start" batteries from a 12 volt tow truck or service vehicle.

OEM Battery Chargers Charging 12 volt electric bicycle from a vehicle.

Universal Power Input OEM Power Supplies and OEM Battery Chargers Four stage charge--constant current, constant voltage, fill, and float. This charges your battery the fastest way possible without damaging the battery. It is suitable for any size 12 volt lead acid battery.

Universal Power Input OEM Power Supplies and OEM Battery Chargers Charge efficiency is 95% for the a SLA, VRLA, or Gel Cell battery and 90% for the charger, making a combined efficiency of 85%. So a 12 volt 100 AH battery would be able to charge a 12 volt 10 AH battery 4 or 5 times before the host battery needs recharging.
