Which Battery Testing Solution Should You Choose?

Quick Overview: DEKRA Battery Readout

Our battery readout is the quick option for those who want an instant snapshot of the battery’s estimated performance. The solution is based on a static readout via the vehicle’s OBD port, where DEKRA’s equipment retrieves data directly from the vehicle’s own battery management system (BMS). DEKRA Battery Readout is based on the vehicle’s own data and provides a quick overview of the high-voltage battery. The result is presented on a scale from 1 to 100 and provides an indicative picture of the battery’s capacity in a summary report. The entire process takes only approximately three minutes.

Best suited for:

• Quick checks during trade-ins, in inventory, or at the workshop.
• Indication during lease returns.
• Quick valuations and transactions.

DEKRA Battery Readout is simply the choice when speed and simplicity are most important.

In-Depth Analysis: DEKRA Battery Test

Our patented and independent battery test is DEKRA’s most comprehensive battery testing solution. Here, static data collection via OBD is combined with a dynamic phase where the vehicle is briefly accelerated. The method measures, among other things, the battery’s resistance to determine actual degradation.

The test takes approximately 10–15 minutes and results in a certificate that shows how much the battery has degraded compared to a brand-new vehicle of the same model.

Best suited for:

• Purchase and sales decisions.
• Independent valuation.
• Comparisons between vehicle models.
• Situations where high accuracy is required.

DEKRA Battery Test is therefore the right choice when you need maximum reliability and a strong decision-making basis.

Which Solution Should You Choose?

Choose DEKRA Battery Readout when you need a quick and convenient answer to the battery’s estimated performance. Choose DEKRA Battery Test when you need an accurate, independent, and comparable result that holds up in a business situation. Do you need both speed and depth? Many businesses use our battery readout as an initial screening and our battery test when a vehicle requires a comprehensive analysis.

With DEKRA’s Software as a Service solution (SaaS), car dealers and workshops gain access to a professional and independent system for battery testing of electric vehicles and plug-in hybrids. The solution is developed to meet increased requirements for transparency, documentation, and efficiency in the used car trade. The SaaS solution makes it possible to perform battery tests directly in your own business – quickly, systematically, and quality-assured!

Same Equipment – Two Levels of Analysis

A major advantage of our battery testing solutions is that both DEKRA Battery Readout and DEKRA Battery Test are performed with the same testing equipment. This means you do not need to choose technology or installation in advance – the same system can deliver two different levels of analysis depending on your needs.

In practice, both tests begin with a secure connection via the vehicle’s OBD port. From there, the process can either stop at a quick static reading (battery readout) or be supplemented with the dynamic measurement required for a complete battery test and certificate.
