The Oxford Products Oximiser Pro 900 charges a range of 6V and 12V batteries at a maximum charge rate of 800mA (0.8 Amps). The intelligent 7-stage automatic charging ensures that every battery is correctly and safely charged to its optimum voltage before switching into maintenance mode, extending the battery's life. Each charging program is tailored to the selected battery type, compatible with WET/MF, AGM, GEL, and LiFePO4 batteries. During the charging profile, a desulfation stage automatically repairs damaged batteries, bringing them back to life (not LiFePO4).

The clear, easy-to-read LCD display assists the user throughout the charging stages, and if required, the charger can be lifted off the ground by clipping it on a removable hanger.
