12V 3300 mA multi-stage recharger with fuel gauge indicating charge process, includes an auto-sensing desulfating feature.
The charger can be left permanently on the battery for maintenance and sulfation prevention. This desulfating charger 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.
Specific charge process(auto 4-stage Ud-Im-Uo-Up):
Stage "Ud" desulfurating the battery through 18V pulse，When the battery recovered,
stage "Im" will give bulk current charging( 3.3A or 2.0A).
"Uo" stage is followed, the output voltage is limited on 14.7V
When the battery is nearly full, stage"Up" will turn on duty. At this stage, the battery is charged completely and the charger give some pulse to maintenance the battery.
