The following table describes the display of LED lights at different
stages of charging:
Q: Can I leave the battery continuously on the
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?
Q: If I discharge the battery while
the charger is attached will the charger maintain a full charge?
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
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

Microprocessor controlled 4 stage adaptive charging algorithm suitable for
12V Gel, Absorbed Glass Mat, VRLA, or flooded lead acid batteries.
Fully automatic without intervention.
Output short circuit and battery polarity protections. Input low voltage and
high voltage connections.
Charging 12V batteries from a 24V vehicle.
Charging 12V "jump start" batteries from a 24 volt tow truck or service
Charging 12V electric bicycle from a 24V 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 12V lead acid battery.
Charge efficiency is 95% for the a SLA, VRLA, or Gel Cell battery and 85%
for the charger, making a combined efficiency of 81%. So a 12 volt 100 AH
battery would be able to charge a 24 volt 10 AH battery 4 or 5 times before the
host battery needs recharging.
- A qualified automotive electrical technician should be used
to wire the charger into the vehicle.
- The PBCD72-24-12 converts 24 volt power into 12 volt power,
so for a 5 amp output the input needs over 2.5 amps. Make sure that the wires
connecting the PBCD72-24-12 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
- PowerStream can supply the connector that fits into many
wheelchairs ( we have the 3 pin XLR style in stock
). Consult the manufacturer or a wheel chair technician to obtain the proper
cable and plug. (If you know about such things please educate us!)
- It is OK to leave the unit on the charger when the power to
the charger goes on and off.
- Mount the PBCD72-24-12 in an area that will get adequate
ventilation and will be free from rain, spray, or excessive dust.
