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 control the "hi"
and "lo" current settings. We can adjust them here or give you the procedure to
do the adjustments.
Applications:
 Charging wheel chairs,
bicycles, and scooters in a car, van 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.
Output short circuit and
battery polarity protections. Input low voltage and high voltage
connections.
Charging 24 volt batteries
from a vehicle.
Charging 24 volt "jump
start" batteries from a 12 volt tow truck or service vehicle.
Charging 24 volt electric
bicycle from a vehicle.
Note: For the higher
current models the input current is too high for a cigarette lighter socket to
handle. This charger must be wired into the battery-alternator circuit of your
car or van.
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.
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:
- A qualified automotive electrical technician should
be used to wire the charger into the vehicle.
- The BC-1224-10 converts 12 volt power into 24 volt
power, so for a 5 amp output the input needs over 10 amps. Make sure that the
wires connecting the BC-1224-10 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 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!)
- 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-1224-10 in an area that will get
adequate ventilation and will be free from rain, spray, or excessive dust.
