- Medical approval: Certified according to EN 60601-1 (3rd edition) for safe operation in medical environments.
- High performance: With a charging current of 10 amps, it provides enough power to get batteries ready for use again quickly.
- Dedicated input: Designed for an input voltage range of 198 - 264 VAC, ideal for stable 230V networks.
- Solid protection (IP21): The housing offers protection against solid foreign objects (>12mm) and vertically falling dripping water.
- Clear status display: A 3-colour LED display (orange/yellow/green) provides information about the current charging status at a glance.
Precise charging technology for 12V systems
The Mascot 9740 utilises an efficient 3-stage charging process (3-Step Charge). In the first phase (cycle), the device charges with a constant current of 10A until the final charging voltage of 14.7V is reached. This is followed by a timer-controlled phase with constant voltage to ensure complete saturation of the battery chemistry. Finally, the device switches to trickle charging (float at 13.7V) to keep the battery fully charged and ready for use.
Ideal for medical and industrial applications
This charger was developed for applications that require reliability. It is perfect for power wheelchairs, larger patient lifts or industrial cleaning machines. The combination of high charging power and medical certification makes it a proven solution for critical systems.

FAQs about the Mascot 9740-12 charger
What does the input voltage range 198-264V mean?
This range indicates that the charger is specifically optimised for operation on European 230V networks (or comparable voltages). It is not suitable for use on 110V networks (e.g. USA), but often offers more robust performance in the intended voltage range.
Can I leave the charger permanently connected to the battery?
Yes, the Mascot 9740 is designed for continuous operation. Once the charging process is complete, the device switches to maintenance charging mode (float, 13.7V). This compensates for self-discharge and keeps the battery fresh without exposing it to thermal stress.
For which battery capacities is it suitable?
Due to the high charging current of 10 amps, this device is ideal for 12V batteries with a capacity between approx. 40 Ah and 200 Ah. Smaller batteries should only be charged if they are approved for such high charging currents.
What do the LED colours mean?
- Orange: Main charging with maximum current (the battery will be charged quickly).
- Yellow: Timer phase with constant voltage (saturation phase).
- Green: Maintenance charge (battery is full and can be removed or left connected).
