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: Yes.
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.


OEM Battery Chargers Charging 12V wheel chairs, bicycles, and scooters in a car, van or bus.

OEM Battery Chargers Charging 12V electric bicycle from a 24V 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 12V 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 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.

Installation Notes:
  1. A qualified automotive electrical technician should be used to wire the charger into the vehicle.
  2. 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 lengths).
  3. 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!)
  4. It is OK to leave the unit on the charger when the power to the charger goes on and off.
  5. Mount the PBCD72-24-12 in an area that will get adequate ventilation and will be free from rain, spray, or excessive dust.
