Battery, Charging with Midtronics Diagnostic Conductance Charging Station INC-940

WARNING: This page does not describe the selected car, but rather 16 other vehicles, including the 2009 Audi S4, 2009 Audi A4, 2008 Audi S4, 2008 Audi RS 4, and 2008 Audi A4. However, it is still accessible from the selected car via links, so may be relevant.

The Midtronics Diagnostic Conductance Charging Station INC-940 (also known as "inCHARGE 940" ) integrates battery conductance and load testing with charging.

NOTE:

Battery charger Midtronics Diagnostic Conductance Charging Station INC-940 charges without current and voltage peaks. Batteries can therefore be charged when installed. When doing this, heed all safety precautions.
When performing electrical troubleshooting or otherwise working on the electrical system with consumers temporarily switched on, and for working with any of the VAS 505X class testers in operating mode "Guided Fault Finding" , the battery must be charged during these procedures with a battery maintainer in battery support mode to prevent damage to the battery → Battery, Support Mode with Midtronics Battery Maintainer PSC-550 or Midtronics Battery Maintainer CXC-2115 .

CAUTION: Risk of injury from battery acid.

Prior to handling or servicing batteries, read, understand and observe the Warnings and Safety Measures for lead-acid batteries for lead-acid batteries → Safety Precautions !
Wear protective eyewear and clothing → 27 - Battery, Starter, Generator, Cruise control .
On non-maintenance-free batteries, the sealing plugs must be installed tightly.
Provide sufficient ventilation.

If the magic eye has no color or is light yellow, the battery may not be tested or charged. Jump starting must not be used! There is a risk of explosion during testing, charging or jump starting. The battery must be replaced.
DO NOT battery test batteries which are gassing. Otherwise there is a risk of explosion.
Rapid-charging batteries → Battery, Quick Charging .
Dispose of electrolyte (sulfuric acid/water mixture) properly! Waste electrolyte must only be disposed of in appropriate waste disposal sites. Refer to local regulations pertaining to electrolyte disposal.

The following notes and procedures must be followed to ensure correct charging.

CAUTION: Risk of damaging AGM batteries.

Specific charging procedures are required for AGM batteries.
