Intelligent microcontroller with smart charge logic maximises battery performance and even charges deeply discharged batteries for a wide range of battery chemistries

(For immediate release) Norwegian power design expert Mascot AS introduces its versatile high-quality, high-performance battery charger, the new model 3743. It uses a 3-stage charging profile with a microcontroller to maximise battery performance for a wide range of battery chemistries, including Lead-Acid and Lithium. The new charger 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. More voltage versions and other battery chemistries to come.

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. Custom units are available on request.
