Stecamat 820
Processor-controlled charger for lead batteries
Description
The Stecamat 820 battery charger is available in a lightweight, compact housing. The battery is charged gently and quickly by the processor-controlled charging process. By setting the nominal capacity, the current, voltage, time and ideal monitoring of the battery can be individually adjusted. This also allows for pre-damaged or deeply discharged batteries to be treated, making a long service life possible with the Stecamat 820. A light-emitting diode provides quick information about the charging status.
The extensive equipment ensures maximum flexibility in use. This equipment and the easy operation, even with gloves, ensure seamless operation.
