Akkusockel eines BQ-Akkus (HTE-3-Schrauben). In unbelastetem Zustand (Akku nicht eingesetzt) misst man anstelle von 12 V ca. 10 V<\/figcaption><\/figure>\n<\/div>\n\n\n Spare parts<\/h3>\n\n\n\n
The Rosenberger connector and the charging socket in the battery are not available as spare parts from Stromer.<\/p>\n\n\n\n
DIY solution<\/strong><\/p>\n\n\n\n
As an alternative, you can get a Wicket Cable (Stromer Art. No. 402336<\/a>) buy and repurpose it as a charging plug. A possible supplier for the Rosenberger Connectors and Sockets<\/a> is, for example, Mouser Electronics.<\/p>\n\n\n

Charging base battery<\/strong><\/p>\n\n\n\n
The charging port on the BQ batteries is not available separately. However, it should be identical to the charging port.<\/p>\n\n\n\n
Contact problems \/ corrosion<\/h3>\n\n\n\n
In combination with current flow and moisture, the plug connection tends to corrode and form verdigris. Due to its magnetic properties, it also attracts even the smallest metal particles. These properties can lead to leakage currents or short circuits. The connections must be kept clean.<\/p>\n\n\n
