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, but there is an 80mA draw from the battery..
Q: Can the charger be adjusted to lower currents?
A: Yes. There are two trimpots that we can adjust here or click here to view the instructions


OEM Battery Chargers Inexpensive DC input charger.

OEM Battery Chargers Protects even small 24 volt batteries from gassing or damage.

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 24 volt 100 AH battery would be able to charge a 24 volt 10 AH battery 8 or 9 times before the host battery needed recharge.


OEM Battery Chargers Charging wheel chairs, bicycles, and scooters in a humvee, firetruck or bus.

OEM Battery Chargers Microprocessor controlled 4 stage adaptive charging algorithm suitable for Gel, Absorbed Glass Mat, VRLA, or flooded lead acid batteries.

OEM Battery Chargers Fully automatic without intervention.

OEM Battery Chargers For Charging 24 volt sealed lead acid batteries or gel cells from a 24 volt vehicle or other 24 volt source.

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 24 volt lead acid battery.

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

OEM Battery Chargers Charging 24 volt "jump start" batteries from a 24 volt tow truck or service vehicle.

OEM Battery Chargers Charging 24 volt electric bicycle from a 24 volt vehicle.

Installation Notes:
  1. A qualified automotive electrical technician should be used to wire the charger into the vehicle.
  2. PowerStream has 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!)
  3. The BC-2424 converts 24 volt power into 24 volt power, so for a 5 amp output the input needs over 6 amps. Make sure that the wires connecting the BC-2424 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).
  4. Try to connect or disconnect the battery when the charger power is "on." It is possible but extremely rare for the charger to go into a fault mode if the battery is connected first, but cycling the power switch will clear this "false fault."
  5. It is OK to leave the unit on the charger when the power to the charger goes on and off.
  6. Mount the BC-2424 in an area that will get adequate ventilation and will be free from rain, spray, or excessive dust.
