CTEK PRO25 Professional Battery Charger - Extra Long Lead Version

The CTEK PRO25 Professional Battery Charger is designed for powering and charging 12V batteries during workshop tasks such as diagnostics, programming, and electrical testing. It delivers up to 25A of stable power, maintaining voltage even under load to help prevent data loss or ECU faults. Compatible with all 12V battery types including lead-acid and lithium (LiFePO4), it features an 8-step automatic charging programme with analysis, reconditioning, and maintenance modes. Temperature compensation supports use between -20°C and +50°C for safe, accurate charging in different conditions. With a 2V start-up capability and built-in protection, it safely restores deeply discharged batteries and protects sensitive vehicle electronics.Explore the key technical features that deliver reliable results in workshop environments:Automatic Parallel Load Compensation: This feature monitors changes in battery load and adjusts power output in real time, ensuring stable amperage during diagnostics and programming, which prevents power drops that could interrupt fault-finding or data retrieval tasks.Fast 8 Step Automatic Charging Cycle: The unit uses a fully automated 8-step process that includes battery analysis, charging, reconditioning and maintenance, delivering efficient charge control that extends battery life and reduces the risk of overcharging or underperformance.Automatic Temperature Compensation: Integrated sensors adjust the charging voltage in relation to ambient temperatures ranging from -20°C to +50°C, improving charging accuracy and reducing the risk of battery damage in colder or warmer workshop conditions.RECOND Mode for Deeply Discharged Batteries: This mode applies a controlled reconditioning charge to deeply discharged lead-acid batteries, restoring performance by desulphating battery plates, which helps recover batteries that would otherwise be replaced.Low Voltage Start Up Capability: With the ability to begin charging from as low as 2V, the charger can engage with heavily depleted batteries, allowing you to recover batteries previously considered unusable without additional equipment.Extremely Low Ripple Voltage: This design minimises voltage and current fluctuations during charging, reducing stress on vehicle electronics such as ECUs and sensors, making it safe for prolonged connection during diagnostics.Cable Length and Mounting Options: The PRO25S comes as the standard version with a compact design and shorter cable suited to portable use around the workshop, while the PRO25SE is the extra-long lead version featuring a 6 metre output cable for extended reach and a fixed wall mounting bracket for permanent installation, allowing you to choose between a mobile setup or a fixed charging station depending on your workspace requirements.The PRO25 helps you maintain consistent, clean power during diagnostics and repair, supporting both battery health and vehicle data integrity. Its automatic functions and low-interference design allow you to carry out power supply and charging tasks with minimal setup and oversight. A practical addition to your workshop setup, this unit is a smart choice for keeping your charging process safe, accurate and efficient across a wide range of 12V battery types.The PRO25 features a 2-year manufacturers warranty.CTEK PRO25 Product Information Sheet
