The Telwin ALPINE 15 is more than just a charger – it is a testament to Italian engineering and decades of experience in manufacturing equipment for professionals. At its heart is a robust transformer, guaranteeing stable charging parameters and exceptional resistance to mains voltage fluctuations or harsh working conditions such as dust and humidity typical of workshops. The metal housing not only protects the internal components, but also ensures adequate heat dissipation, which translates into a long life of the device.

When you choose Telwin, you are investing in equipment designed for intensive daily use. The simple but thoughtful design minimizes the risk of failure, and the high-quality materials used for terminals and cables ensure a secure connection and minimal energy loss. It’s this attention to detail that makes professionals around the world trust the Telwin brand, valuing its products for reliability that translates into continuous operation and no unforeseen downtime.

Safety is key when working with batteries, so the Telwin ALPINE 15 is equipped with a number of safety features to protect both the user, the device and the battery itself. Overload protection automatically interrupts the charging process if the current draw is too high, which could damage the charger or the battery. Polarity-swap protection is invaluable – even if you connect the clamps in reverse by mistake, the device will not start charging and will signal an error, preventing sparks and potentially dangerous situations.

In addition, terminal short-circuit protection protects the rectifier from damage if the plus and minus terminals accidentally come into contact. These integrated protection systems make working with the ALPINE 15 stress-free and safe, even for less experienced users. For the professional workshop, this means less risk of costly mistakes and equipment damage, which translates into greater efficiency and peace of mind during daily tasks.

The Telwin ALPINE 15 offers a two-stage charging current adjustment, allowing the parameters to be fine-tuned to the specific battery being charged. Selecting a lower current (“MIN” position) is ideal for batteries with lower capacity, typically for motorcycles or small cars, as well as for maintenance charging or when time is not a priority. Gentler charging with lower current is often more beneficial to the condition of the battery, minimizing overheating and gassing.

The “MAX” position provides a higher charging current, reducing the time required to charge larger batteries, such as those in vans or machinery. The ability to select the appropriate current, combined with monitoring of the process using the built-in ammeter, allows optimization of the charging process. This, in turn, translates into better utilization of the battery’s capacity, prevention of its sulfation and, ultimately, extension of its service life. For the professional, this saves time and money, and for the hobbyist, it ensures that his batteries are treated with proper care.

One of the biggest advantages of the Telwin ALPINE 15 charger is its extreme versatility, which comes from its ability to charge 12V and 24V batteries. This feature makes it an ideal tool for workshops servicing a diverse fleet of vehicles, as well as for discerning private users with various machines and vehicles. You can easily charge the battery in your motorcycle, passenger car, quad, as well as in a van, small truck or agricultural tractor running on a 24V system.

The range of supported battery capacities (reference 60Ah to 115Ah for 12V and 30Ah to 55Ah for 24V) covers most common types of lead-acid batteries (WET). This means you don’t have to invest in several different chargers – the ALPINE 15 will meet most of your daily charging challenges. It saves space, money and simplifies equipment logistics in every garage and workshop.
