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
Q: Can I charge my 12 volt golf caddy from my
car?
Yes, the charge time should be less than 2 hours for a fully
depleted golf trolley.
Advantages:
 Inexpensive DC input charger.
Protects even small 12 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 100 AH 12 volt
battery would be able to charge a 10 AH 12 volt battery 8 or 9 times before the
host battery needed recharge.
Installation Notes:
- A qualified automotive electrical technician should be
used to wire the charger into the vehicle.
- The BC-1212-15 converts 12 volt power into 13.8 volt
power for charging, so for a 7.5 amp output the input needs over 9 amps. Make
sure that the wires connecting the BC-1212-15 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). If 9 amps is not available we (or you) can also lower
the output current by internal adjustments to match your needs.
- PowerStream does have 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-1212-15 in an area that will get adequate
ventilation and will be free from rain, spray, or excessive dust.
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 12 volt sealed lead acid batteries from
a vehicle.
Charging 12 volt "jump start" batteries from a
12 volt tow truck or service vehicle.
Charging 12 volt electric bicycle from a
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.
