PRO25S is light and portable and ideal for technicians use in the busy workshop. It’s fully automatic so it’s easy to use and its reliable, 12V power supply keeps the vehicle’s stored data safe and prevents damage to sensitive ECUs and other vehicle electronics. It features fast, 8-step charging, temperature compensation for ambient conditions between -20°C and +50°C (-4°F to +122°F), and is suitable for use with any 12V battery, including lithium*. PRO25S features automatic parallel load compensation so power supply and amperage are always constant and accurate, even if an additional load is placed on the battery during diagnostics. It also has a ‘RECOND’ mode to bring deeply discharged lead-acid batteries back to life and a lithium ‘wake up’ mode for batteries with under voltage protection. *) 12V lithium batteries (LiFePO4, Li-Fe, Li-iron, LFP)
