Why do I need CTEK battery support?

Battery support is an essential tool for all types of troubleshooting, maintenance and repairs in a professional repair shop. CTEK's PRO25SE offers a powerful 12V power supply, charging and maintenance programs in a versatile, highly efficient device that helps save valuable time and money. 

Like all CTEK PRO series products, the PRO25SE has automatic parallel charge compensation, which ensures that the supply voltage and current are always constant and correct, even if the battery receives an additional charge during diagnostics.


Fully automatic 8-step charging 
Press the MODE button to select a program and let it  do the rest. An easy-to-read graphic display shows where the device is in the charge cycle. 

Strong, safe and reliable 
Durable 6 meters of charging cables. Protection class IP44, protection against short circuit  and  2-year warranty. 

12V power supply  
Reliable 12V power supply to support battery diagnostics and maintenance to prevent loss of stored data or damage to vehicle ECUs and other sensitive electronics.

'LITHIUM' mode
Separate compartment for lithium iron phosphate batteries. Automatically or manually "wakes up" batteries with undervoltage protection (UVP).

'RECOND' mode
At the end of the "STANDARD" program, a "RECOND" step was added for lead-acid batteries to revive deeply discharged batteries.

Automatic temperature compensation
The temperature sensor can be attached inside the positive clamp or as close as possible to the battery. It automatically adjusts the voltage according to the ambient temperature between -20°C to 50°C (-4°F to 122°F), reducing the risk of over or undercharging.
