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.
- A qualified automotive electrical technician should be used
to wire the charger into the vehicle.
- 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).
- It is OK to leave the unit on the charger when the power to
the charger goes on and off.
- Mount the PBCD305-12-12 in an area that will get adequate
ventilation and will be free from rain, spray, or excessive dust.
Applications:
Charging wheel chairs, bicycles, and scooters in a car, van or bus.
Fully automatic without intervention.
Output short circuit and battery polarity protections. Input low voltage and
high voltage connections.
Charging 12 volt batteries from a vehicle.
Charging 12 volt "jump start" batteries from a 12 volt tow truck or service
vehicle.
Charging 12 volt electric bicycle from a vehicle.
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.
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.
