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: Yes, but if the load is higher than the
rated current the voltage will reduce, typical of a constant current output.
.
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 I charge my 12 volt golf caddy from my
car?
Yes.
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 PST-DBC1212 converts 12 volt power into 13.8 volt
power for charging, so for a 10 amp output the input needs over 12 amps. Make
sure that the wires connecting the charger 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).
- It is OK to leave the unit on the charger when the
power to the charger goes on and off.
- Mount the PST-DB1212 in an area that will get adequate
ventilation.
Applications:
Charging wheel chairs, bicycles, and scooters in
a car, van or bus.
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 electric bicycle from a
vehicle.
