On-site diagnosis & fault analysis
When batteries, chargers or charging points fail to work reliably, prompt and targeted assistance is essential: we analyse faults directly at your premises, investigate the causes using appropriate measurement equipment and provide clear recommendations for repairs, replacements or further action.
Service request
  • rapid root cause analysis for battery, charger and charging point issues
  • on-site inspection including measurements, visual checks and fault assessment
  • clear recommendations for repair, maintenance or replacement
Our diagnostics and fault analysis are ideal for:
  • forklift fleets and industrial trucks
  • traction, service and stationary batteries
  • chargers, charging stations, battery rooms and fixed installations

Overview of services

Our fault analysis helps to quickly pinpoint faults, assess their causes in a transparent manner and take the appropriate next steps.

On-site diagnosis in the event of faults

We inspect batteries, chargers and the charging environment directly at your premises if operating times are decreasing, charging processes are being interrupted or systems are not operating reliably.

measurement of relevant battery parameters

Testing of voltage, cell or block values, acid density, temperature, internal resistance and other condition parameters – tailored to the specific battery type.

Testing of chargers & charging behaviour

Checking the charger, charging profile, charging power, connectors, charging cables and any potential faults in the charging process.

Analysis of connection and contact problems

Testing of poles, bridges, cables, plugs, connectors and contact resistances to detect contact faults or damaged components.

Visual and safety inspection

Inspection of the housing, battery tray, ventilation, dirt, corrosion, fluid levels and any safety-related anomalies.

Error report and recommended action

You will receive a clear assessment of the cause, along with specific recommendations for repair, cell replacement, maintenance, reconditioning or replacement.

​Service packages for every need

Sie entscheiden, wie umfangreich die Fehleranalyse ausfallen soll. Vom schnellen Basis-Check bis zur detaillierten Vor-Ort-Diagnose – transparent, planbar und passend zu Ihrem Einsatz.
package 1

Basic check

Ideal for a quick initial assessment of individual issues or smaller systems.
  • visual inspection of the battery, connections and charging environment
  • voltage measurement and simple condition assessment
  • brief assessment of possible causes of faults
  • test report for your records

Package 2

Comfort test

For businesses with regular use and high operational safety requirements.
  • advanced measurement of battery and charger data
  • inspection of plugs, cables, terminals and connectors
  • assessment of charging behaviour, runtime and usage profile
  • test report with specific recommendations for action
Package 3

Full service analysis

For forklift fleets, stationary systems and critical applications requiring high availability.
  • comprehensive diagnostics of the battery, charger and charging station
  • measurement of relevant cell, block and system parameters
  • stress and functional testing as required
  • detailed fault report with prioritisation of corrective actions
  • optional: direct initiation of repairs, cell replacement or maintenance

This is how our on-site fault analysis works

Clearly structured processes ensure that faults are investigated in a transparent manner – from the initial enquiry right through to a specific recommendation.

1. Enquiry & fault description

Please provide us with the application, battery type, charger, symptoms and any previous issues such as short runtime, charging interruptions, error messages or start-up problems.

2. Booking an appointment & preparation

We will arrange a suitable service appointment and prepare measuring equipment, test equipment and, if necessary, standard spare parts.

3. On-site diagnosis

We inspect the battery, charger, connections and charging environment – from visual and functional checks to measurements and stress tests.

4. Documentation & recommendations

You will receive a clear assessment of the cause of the fault, measurement results and specific recommendations for the next steps.

Your advantages

Our diagnostics and fault analysis provide clarity, reduce downtime and help to avoid unnecessary costs resulting from inappropriate measures.

Rapid identification of the cause

Problems are systematically narrowed down so that the appropriate action can be taken more quickly.

Less downtime

Early fault detection helps to reduce breakdowns of vehicles, machinery or plant.

Secure decisions

Measurement data and fault reports help in deciding whether to repair, service, recondition or replace the component.

Action steps that can be planned

You will receive clear recommendations so that repairs, spare parts or further service visits can be planned effectively.

Ready for a quick explanation of error?

We’d be happy to assess any issues you’re having with your battery, charger or charging point directly at your premises and provide you with a clear assessment of the cause – practical, easy to understand and solution-focused.
