?? TRONIC Technology: Intelligent Care for Your Battery
The TRONIC system in the TELWIN AUTOTRONIC 25 BOOST charger is a guarantee of optimal and safe charging of any lead-acid battery, including modern WET and START-STOP (AGM/EFB) types. The technology involves continuous monitoring of the voltage at the battery terminals and automatic adjustment of charging parameters.
The main advantage of the TRONIC system is that it automatically interrupts the charging process when the battery reaches full charge. This prevents the phenomenon of overcharging, which is one of the main causes of shortened battery life. What’s more, the TRONIC system automatically resumes charging if it detects a drop in voltage, keeping the battery in a constant state of readiness. For the professional, this means the battery can be plugged in for an extended period of time without the risk of damage – ideal for seasonal vehicles or those awaiting repair. It’s a real convenience and reassurance that power will always be available.
?⚡ Instant Start with BOOST Function: Power When You Need It
The BOOST function of the AUTOTRONIC 25 BOOST is a real lifesaver in emergency situations. When the battery is too weak to start the engine on its own, it’s this function that delivers a powerful current boost (up to 150A) to help start cars, vans, and even light agricultural and construction machinery with both 12V and 24V systems.
Operation of the BOOST function is simple and intuitive. All you have to do is connect the charger, select the appropriate voltage and start mode. This is an invaluable support in automotive workshops, where response time is crucial, as well as for private users who want to avoid problems with starting a vehicle when least expected, such as during the cold winter. The speed and efficiency of the BOOST function minimize downtime and allow mobility to be restored immediately. It’s a reassurance that even with a capricious battery, the engine will start without a problem.
?️✅ Safety First: Protecting the Battery and the User
The TELWIN AUTOTRONIC 25 BOOST is designed for maximum safety of both the battery being charged, the vehicle’s electronics and the user himself. The device is equipped with a comprehensive safety system that protects against the most common operating errors and failures.
Key safeguards include terminal swap protection, which prevents damage to the charger and battery if the terminals are connected incorrectly – a special indication indicates the mistake. In addition, the charger has overload protection and terminal short-circuit protection. These features ensure that even in the event of unforeseen situations, the device will remain operational and the charging or starting process will be safe. For the professional, this means smooth operation and less risk of costly breakdowns of the customer’s equipment or vehicle.
