Small lead acid car charger with desulfation functionside view of the 12V 1500mA lead acid charger

12 volt 1500mA, peak multistage charger with AC input. Connection to the battery with barrel connector or alligator clips. Suitable for all flooded and sealed lead acid technologies


This is a nice little 1.5 x 2 x 3.5 inch precision charger which uses switchmode technology rather than transformer technology. Switchmode makes it smaller, lighter, more efficient, and ensures a high degree of voltage regulation no matter what the AC input voltage is. This makes it particularly useful when the car is a long way from the AC outlet because it compensates for AC voltage drop in the extension cord.
