Why use a battery manager during diagnostics?
When programming control modules, performing software updates, or during long diagnostic sessions, a modern vehicle consumes a lot of power. If the battery voltage drops too low, an update can fail, or a module can be damaged. A battery manager with a BSU function keeps the voltage stable, allowing you to work safely with diagnostic tools from brands like Autel, Launch, or Jaltest.
Doctor Charge 130 or 131?
Both have the same technical specifications and features. The difference lies in the cables: the Doctor Charge 130 has 3 m charging cables, while the Doctor Charge 131 has 6 m cables, useful in a large workshop or for reaching a vehicle in the showroom. Optional accessories include 10 m charging cables, a mounting bracket set, and a diagnostic trolley.
