Focus on workshop battery support, says Ecobat Battery
13 October 2025 
Reflecting the fact that diagnostic procedures are now a fundamental part of vehicle servicing, and are only likely to grow in their importance, Ecobat Battery is adding to its previous message highlighting the need to actively support the battery when running diagnostic processes, with more useful information that will allow workshops to work more efficiently and enhance their reputation.
Due to the fact that many diagnostic processes and associated software updates can take several hours, maintaining the correct voltage in the electrical system is vital to perform them successfully. This therefore requires a stable source of power, at the correct voltage, to be constantly supplied to the vehicle’s electrical system.
Naturally, to supply the necessary power requires the right equipment, which is where Ecobat Battery is steering the conversation, and alongside its primary automotive sector charging partner, CTEK, providing them with the extra information they need, specifically highlighting the dangers of de-rating.
De-rating is the process by which electronic equipment reduces its output capacity to prevent overheating or protect internal components from damage due to excessive load or temperature conditions, and in the workshop, this phenomenon can have a significant impact. When chargers or battery support units de-rate, they may fail to provide the stable voltage required for critical vehicle operations. This can lead to disrupted diagnostics, aborted ECU programming, or malfunctioning electronic systems.
Given the sensitive nature of modern automotive electronics, avoiding de-rating during servicing is crucial. This underscores the need for high quality, reliable battery support units that can maintain their output even under demanding conditions.
Diagnostics
Investing in reliable battery support systems ensures that technicians can carry out diagnostics, software updates, and complex repairs without the risk of voltage drops. A stable and consistent power supply prevents unnecessary disruptions and protects sensitive vehicle electronics.
So, when selecting a battery support unit, workshops should only consider units that maintain a stable voltage, even under heavy loads, and prevent heat build up that could lower output and disrupt operations. In addition, the unit must be designed to handle diagnostics and ECU programming, and provide a precise voltage control, to protect sensitive vehicle electronics.
The sheer number of electronic components now utilised in vehicles has made stable voltage a critical factor in workshop operations. From the infotainment system to ADAS (advanced driver assistance systems), virtually every aspect of modern vehicles relies on a stable electrical supply. Voltage fluctuations during servicing can corrupt data, damage sensitive components, and lead to unwanted extra costs.
These combined factors position the CTEK PRO120 as the ideal solution to these important issues, as it is a high performance battery support and charging unit that delivers up to 120A of stable power without de-rating, even under demanding conditions. This ensures uninterrupted support for diagnostics, ECU programming, and complex vehicle repairs.
As highlighted, safeguarding diagnostic procedures is now a necessity, but alongside this reality is the fact a battery performs best when it’s in peak condition. Therefore, the combined benefits of competently undertaking complex diagnostics, while also reducing the likelihood of battery failure, is great for customers and helps raise the reputation of the workshop.
