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 a 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:

OEM Battery Chargers Inexpensive DC input charger.

OEM Battery Chargers Protects even small 6 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 100 AH 12 volt battery would be able to charge a 10 AH 6 volt battery 16 or 18 times before the host battery needed recharge.

Applications:

OEM Battery Chargers Charging 6 volt lead acid batteries using 12 volt DC sources, such as cars, vans, wheel chairs, bicycles, and scooters.

OEM Battery Chargers Microprocessor controlled 4 stage adaptive charging algorithm suitable for 6V Gel, Absorbed Glass Mat, VRLA, or flooded lead acid batteries.

OEM Battery Chargers Fully automatic without intervention.

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

OEM Battery ChargersCharging 6 V sealed lead acid batteries from a vehicle.

OEM Battery ChargersCharging 12 volt electric bicycle from a vehicle.

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 6 volt lead acid battery.


Installation Notes:
  1. A qualified automotive electrical technician should be used to wire the charger into the vehicle.
  2. The BC-1206-15 converts 12 volt power into 7.9 volt power for charging, so for a 7.5 amp output the input needs over 6 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 6 amps is not available you can turn down the maximum charging current with the internal pots to match your needs.
  3. PowerStream does have the connector that fits into many wheelchairs ( we have the 3 pin XLR style in stock ).
  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-1206-15 in an area that will get adequate ventilation and will be free from rain, spray, or excessive dust.
