Every battery deserves the APTO™ touch
17 January 2026
Look at vehicle batteries that need a charge and they all look the same from the outside. You can stick a standard battery charger on and let it progress through its charging modes and hopefully a few hours, or perhaps overnight, you end up with a battery in good enough health.
But on the inside, each depleted battery has its own story to tell. It has its own specific needs and its own way of responding to the intervention of a battery charger being clamped on, powered up and running through its cycles.
There is a better way. It’s smarter, safer and more efficient. It’s CTEK’s exclusive APTO™ adaptive technology.
APTO™ doesn’t proceed step-by-step through a pre-programmed series of modes, even if your battery does not need all of those steps.
APTO™ listens to your battery, it constantly analyses this feedback and creates and executes a bespoke charging algorithm that’s made to measure for your battery, its needs and its responses to the charging process.
Thanks to it being a good listener, a battery charger with APTO™ can be safely and easily used with a wide range of lead acid or lithium battery types without you having to choose which modes should apply and when.
The APTO™ charger checks not only the battery health but also its size, its reactions to the charging process and even the ambient temperature to personalise and adapt what it is delivering to the battery.
With an APTO™ charger from CTEK, you don’t even have to worry about connecting the right clamp from the charger to the correct terminal or the chassis on the vehicle. APTO™ works out what is what and gets on with the task.
So, now you know. Batteries – seen one and you haven’t seen them all.
To put the app into APTO™, this is the ONE
If you would like more insight into what your CTEK APTO™ powered battery charger has been doing, you’ll love the newly updated CS ONE from CTEK.
The CS ONE (Gen 2) battery charger takes the groundbreaking CS ONE even further, with built-in Wi-Fi and a fully redesigned CTEK App. The app provides remote access via WiFi to the real-time monitoring and a complete charge history, enabling the latest CS ONE to give you total control. And that’s whether you are near the vehicle or far away.
You can view save, and export charge histories and session logs, receive alerts, reminders and live push notifications plus access the additional modes RECOND, WAKE UP and SUPPLY. It even enables automatic over-the-air firmware updates.
APTO™ and CS ONE (Gen 2) – a new era for smarter, safer, more efficient battery charging.
