VARTA LCD Multi Charger+ Type 57681
The VARTA LCD Multi Charger+ is a charger for rechargeable NiMH batteries in AA and AAA sizes. It can charge up to eight batteries at a time, but each individual slot can also be used separately. This makes it practical for everyday use, where batteries are rarely depleted to the same extent at the same time.
The charger is powered via USB-C and requires a power supply with at least 9V/2A Power Delivery or 12V/1.25A Power Delivery. A USB-C charging cable is included, but the power adapter itself is not part of the delivery. On the LCD display, you can monitor the charging process, and the display also indicates if a cell is defective, inserted incorrectly, or not compatible with charging.
In practice, it is primarily the safety features that make it suitable for professional use. It features, among other things, minus delta-V termination, a timer-based safety cutoff, reverse polarity and short-circuit protection, as well as detection of alkaline and defective cells. In addition, it monitors the temperature during charging. This means it operates in a more controlled manner than a simple basic charger.
For the user, this provides a clear overview of what is happening during charging, which is an advantage when handling many batteries in daily operations.
Typical applications
- Charging AA and AAA NiMH batteries in workshops, service, and internal operations
- Use in locations where multiple batteries need to be charged individually
- Controlled charging where status and error indication are important
