TRONIC Technology: Smart Care for Your Battery
The TRONIC system in the TELWIN AUTOTRONIC 25 BOOST battery charger guarantees optimum and safe charging of every lead-acid battery, including modern WET and START-STOP (AGM/EFB) types. The technology continuously monitors the voltage at the battery terminals and adjusts the charging parameters automatically.
The main advantage of the TRONIC system is that it stops charging automatically once the battery is fully charged. This prevents overcharging, one of the main causes of shortened battery life. What is more, the TRONIC system resumes charging automatically when it detects a voltage drop, keeping the battery permanently ready. For a professional this means the battery can stay connected for a long time without risk of damage, an ideal solution for seasonal vehicles or vehicles waiting for repair. It is real convenience and the certainty that power will always be available.
Fast Starting with the BOOST Function: Power When You Need It
The BOOST function of the AUTOTRONIC 25 BOOST is a real lifesaver in emergencies. When the battery is too weak to start the engine on its own, this function delivers a powerful current pulse (up to 150A) that assists the starting of cars, vans and even light agricultural and construction machinery, with both 12V and 24V systems.
Using the BOOST function is simple and intuitive. Just connect the charger and select the right voltage and the start mode. It is invaluable support in car workshops, where response time is critical, and for private users who want to avoid starting problems at the least expected moment, for example in a freezing winter. The speed and effectiveness of the BOOST function minimise downtime and restore mobility straight away. You can be sure that even with a temperamental battery, the engine will start without trouble.
Safety First: Protection for the Battery and the User
The TELWIN AUTOTRONIC 25 BOOST was designed for maximum safety of the battery being charged, the vehicle electronics and the user. The unit has a complete protection system that guards against the most common operating errors and faults.
The key protection features include reverse polarity protection, which prevents damage to the charger and the battery if the clamps are connected incorrectly, with a dedicated signal indicating the mistake. The charger also has overload protection and short circuit protection at the clamps. These functions ensure that even in unforeseen situations the unit stays operational and charging or starting remains safe. For a professional this means worry-free work and a lower risk of costly damage to equipment or to the customer's vehicle.

Key Features and Benefits
- Smart TRONIC Charging: The advanced TRONIC system automatically monitors and controls the entire charging process. When the battery reaches the optimum charge level, the charger stops charging by itself and resumes when the voltage drops. For a professional this means certainty that the battery is always fully ready for work and protected against overcharging and sulphation, which significantly extends its life and removes the need for constant supervision.
- Powerful BOOST Start Function: The built-in start assist function (BOOST) delivers a maximum start current of up to 150A, so you can quickly start the engines of cars, vans and even agricultural machinery with flat 12V or 24V batteries. It is a key time saver and eliminates downtime in the workshop or on the farm, especially in sudden, unforeseen situations.
- 12V/24V Versatility: The ability to work with both 12V and 24V batteries makes the AUTOTRONIC 25 BOOST an exceptionally versatile tool.

They cover reverse polarity (with signalling), overload and short circuit at the clamps. This makes working with the AUTOTRONIC 25 BOOST fully safe and minimises the risk of equipment damage and costly repairs.
- Clear Charging Current Indicator: The built-in ammeter lets you monitor the current delivered to the battery during charging as it runs. It gives the user full control and information on charging progress and battery condition, which is particularly useful when diagnosing problems with the charging system or the battery itself.
