DC Source Chargers for charging 12 volt lead acid batteries from a 24 volt (20-30 volt) source
|Inexpensive multistage microcontroller based lead acid battery charger voltage charger with 20 VDC to 30 VDC input. Charge 12 volt lead acid batteries. Charge any lead acid battery from a large one, or from a Humvee, truck, fork lift, truck, tractor or back-hoe.||

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?
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
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.
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.
