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.
Q: Can the charger be adjusted
to lower currents?
A: Yes. There are two trimpots that we can adjust
here or give you the procedure to do the adjustments.
Advantages:
 Inexpensive DC input
charger.
Protects even small 24
volt batteries from gassing or damage.
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.
Applications:
Charging wheel chairs,
bicycles, and scooters in a humvee, firetruck or bus.
Microprocessor controlled
4 stage adaptive charging algorithm suitable for Gel, Absorbed Glass Mat, VRLA,
or flooded lead acid batteries.
Fully automatic without
intervention.
Two current settings for
different battery capacity. Select "low" if the battery is less than 7 AH in
capacity.
Output short circuit and
battery polarity protections. Input low voltage and high voltage
connections.
For Charging 24 volt
sealed lead acid batteries or gel cells from a 24 volt vehicle or other 24 volt
source.
Charging 24 volt "jump
start" batteries from a 24 volt tow truck or service vehicle.
Charging 24 volt electric
bicycle from a 24 volt 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 24 volt lead acid
battery.
Installation Notes:
- A qualified automotive electrical technician should
be used to wire the charger into the vehicle.
- 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).
- 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!)
- 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."
- It is OK to leave the unit on the charger when the
power to the charger goes on and off.
- Mount the BC-2424 in an area that will get adequate
ventilation and will be free from rain, spray, or excessive dust.
