This 6V/12V 1-4A automatic reverse pulse battery charger from Ultipower, it is an eight stage all-purpose universal charger for your scooter, golf, kontiki, caravan/RV, marine or vehicle battery. You can set it to 6V or 12V charging by the switch, and 1, 2, 3 or 4 Amp charging rate by the buttons, this gives you a total of 8 possible chargers, amazing flexibility allows you to charge many different types and sizes of batteries without having to buy a separate charger.
The charger features a digital display to show charge voltage, charge current. Suitable for 12V Gel, Flooded (Calcium) and AGM battery charging.
Automatic reverse pulse desulfation chargers apply an advanced charge algorithm. The reverse pulse will maintain and equalize battery cells during the entire charge process. Unlike some normal chargers which only equalize the cells by increasing the charge voltage after the float phase, Ultipower reverse pulse chargers will lift the cell voltages that are lower than average, and lower the cells that are higher than average, thus avoiding the higher voltage that can cause overcharging and gassing, which causes irreversible damage on sealed batteries.

Reverse Pulse Technology
You can see this on the display in some of the charging stages it will charger for a few seconds and then for a few milliseconds pulse the current in the opposite direction.
1 Reducing battery internal impedance, temperature rise and gassing (by up to 15%)
2 Restore the sulfate into liquid to recover battery capacity.
3 Maintain battery, extend battery service life. This will helps you to cut considerable costs on battery maintenance.
Once you use an Ultipower reverse pulse battery charger you will not use another type ever again.
