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 click here to view the instructions
Advantages:
 Inexpensive DC
input charger.
Protects even
small 12 volt batteries from gassing or damage.
Charge time is
typically 58% charge in 1 hour, 82% in 2 hours, 93% in 3 hours, 98% in 4
hours.
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 12 volt 10 AH battery 16 or 18 times before the host battery needed
recharge.
Applications:
Auxiliary
batteries, hobby batteries, 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 12 volt
sealed lead acid batteries from a vehicle.
Charging 12 volt
"jump start" batteries from a 24 volt tow truck or service vehicle.
Charging 12 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 12 volt lead acid battery.
Installation Notes:
- A qualified automotive electrical technician should be used to wire the charger into the
vehicle.
- The BC-2412-15 converts 24 volt power into 12 volt power, so for a 7.5 amp output the input
needs over 4 amps. Make sure that the wires connecting the BC-2412-15 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 available the connector that fits into many wheelchair (
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 temporary 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-2412-15 in an area that will get adequate ventilation and will be free from
rain, spray, or excessive dust.
