12 Volt lead acid battery charger 1.5 Amp, fully isolated, removable AC cord, desulfating function and state-of-charge indicator

More lead acid battery chargers 6V, 12V, 18V, 36V, 42V, 48V
1.5 amp small lead acid battery chargers 12 volts with desufation function

12 Volt 1500 mA multi-stage recharger with universal AC input. Includes an auto-sensing desulfating feature.

These are state-of-the-art battery chargers that can be used on-demand, or left permanently on the battery for maintenance and sulfation prevention. It uses energy-saving techniques and and and advanced pulsed charging algorithm to allow better control of gas recycling and plate corrosion. The desulfating feature can rejuvenate batteries that have been left uncharged for extended periods of time, such as motorcycle, ATV, and tractor batteries. The charger is fully isolated from the mains, has universal AC input, and a removable AC cord. Although designed for sealed lead acid and gel batteries, these will also accurately charge flooded and automobile batteries.

Charging algorithm
This is the "European" charge algorithm that does not float charge the battery at the last stage, but still keeps it maintained. (see the graph below)
Constant current/constant voltage/float
Stage 1 desulfation. An 18 volt pulse is applied to the battery. When the battery impedance shows the battery is recovered the charger moves to "bulk charge." This could happen within seconds if the battery is not sulfated.
Stage 2 bulk charge stage. 3.5 amps is applied to the battery until the voltage rises to 14.4 volts.
Stage 4 pulsing charge. The current is switched between 300mA and 3000 mA. If, during the 300mA part of the cycle the battery drops below 13.3 volts a new pulse is started. If the voltage stays above 13.3V for more than 30 minutes (verification stage) the charge is terminated.
Stage 5. The voltage is measured and then the voltage falls below 12.7 volts the charger returns to stage 2.
