Mascot introduces model 3743, a versatile, high-quality, high-performance battery charger for Li-Ion batteries. 3743 uses a 3-stage charging profile with a microcontroller to maximise battery performance for Lithium batteries and is also capable of waking up deeply discharged batteries and soft-start charging with low current until voltage is normalized. 

It is well suited for a wide variety of applications from medical to consumer; owners of the new 3743 charger will enjoy optimised uptime and turnaround for battery-powered equipment. The 3743 is medically certified according to EN 60601-1 edition 3.1. It is also UL-approved and meets the latest DoE and CEC efficiency requirements. Five standard versions are initially available for charging Li-Ion batteries from 1 cell (1.5A/4.2V) to 7 cells (0.56A/29.4V) and 12V and 24V lead acid batteries. 

Alternative chargers that terminate the charge on reaching the battery’s threshold voltage can shorten charging time but always leave some capacity unfilled. The 3-stage charge control first restores the full battery voltage and then applies the saturation charge needed to fill the battery completely. This ensures the longest possible battery run-time. 

The 3743 also features a single 3-colour LED indicator light for charge-, error- or standby-status. Its all-new sleek design incorporates the smart and versatile features of exchangeable plugs and universal input for applications all around the world.
