The new portable digital chargers have a built-in digital microprocessor that is the “brain” behind their performance. Among other things, the microprocessor facilitates automatic temperature compensation. This extends battery life and allows for maximum cranking power and improved life cycle for marine electronics.
The Portable Digital Chargers also recognize when the battery has achieved full power, and shut off automatically when the charge is complete. The new models deliver 5 or 10 AMPS of total output. The 5 AMP MK-105PD will retail for $59.99 and the 10 AMP MK-110PD will retail for $84.99.
