Made in Italy Reliability: Telwin Quality Tradition in the ALPINE 15 Charger
The Telwin ALPINE 15 is more than a charger: it reflects Italian engineering and decades of experience in building equipment for professionals. At its heart is a robust transformer that provides stable charging parameters and good resistance to mains voltage fluctuations and to harsh conditions such as the dust and moisture typical of workshops. The metal housing protects the internal components and also dissipates heat properly, which gives the unit a long service life.
When you choose Telwin, you invest in equipment designed for intensive daily use. The simple but well thought-out design minimises the risk of failure, and the high-quality materials used for the clamps and cables give a secure connection with minimal energy loss. This attention to detail is the reason professionals around the world trust the Telwin brand and value its products for a reliability that keeps work going without unexpected downtime.
Full Protection for Your Batteries: the Safety Systems of the ALPINE 15
Safety is essential when working with batteries, which is why the Telwin ALPINE 15 has several protection features that protect the user, the unit and the battery itself. Overload protection automatically interrupts charging if the current draw is too high, which could otherwise damage the charger or the battery. Reverse polarity protection is invaluable: even if you connect the clamps the wrong way round by mistake, the unit will not start charging and will signal an error, which prevents sparks and potentially dangerous situations.
In addition, short-circuit protection at the clamps protects the charger from damage if the positive and negative clamps touch by accident. These integrated protection systems make working with the ALPINE 15 stress-free and safe, even for less experienced users. For a professional workshop this means a lower risk of costly mistakes and damaged equipment, and therefore greater efficiency and calm in everyday tasks.
Optimal Charging, Longer Battery Life: Adjust the Current on the ALPINE 15
The Telwin ALPINE 15 offers two-step charging current adjustment, so you can match the parameters precisely to the battery you are charging. The lower current (the "MIN" position) is ideal for smaller batteries, typical of motorcycles and small cars, as well as for maintenance charging or when time is not a priority. Gentler charging at a lower current is often better for the condition of the battery, as it minimises overheating and gassing.
The "MAX" position gives a higher charging current and shortens the time needed to charge larger batteries, for example in vans or machines. Choosing the right current and following the process on the built-in ammeter lets you optimise the charging process. This makes better use of the battery capacity, prevents sulphation and ultimately extends battery life. For a professional it saves time and money, and a hobbyist can be sure the batteries get the care they need.
A Versatile Partner: From Scooters to Light Commercial Vehicles with the ALPINE 15
One of the biggest advantages of the Telwin ALPINE 15 charger is its remarkable versatility, which comes from its ability to charge both 12V and 24V batteries. This makes it an ideal tool for workshops serving mixed vehicle fleets, and for demanding private users who own different machines and vehicles. You can easily charge the battery in your motorcycle, car or quad, as well as in a van, a small truck or an agricultural tractor running on a 24V system.
The supported battery capacity range (reference values from 60Ah to 115Ah for 12V and from 30Ah to 55Ah for 24V) covers most common lead-acid (WET) battery types. This means you do not need to buy several different chargers: the ALPINE 15 handles most everyday charging jobs. It saves space and money and keeps the equipment in any garage or workshop simple.

Key Features and Benefits
- Universal 12V and 24V Charging Voltage: The ALPINE 15 charger can charge many types of lead-acid batteries used in motorcycles, cars, vans and even some agricultural and construction machines. The voltage selector switch is easy to reach and clearly marked. For a professional this means one versatile unit for a mixed vehicle fleet, with no need for several specialised chargers and more free space in the workshop.
- Full Set of Protection Features: The unit has systems that protect against overload, reverse polarity and short circuit at the clamps. These integrated safety mechanisms minimise the risk of damage to both the charger and the battery on charge, even if the operator makes a mistake. For you this means calm, safe work, which matters in a busy workshop, and protection of valuable batteries against irreversible damage.
- Two-Step Charging Current Adjustment: Choosing one of two current levels lets you match the charging characteristic more closely to the capacity and state of charge of the battery. The lower current is ideal for smaller batteries or trickle charging, while the higher current speeds up the process for larger units. This optimises charging, which can extend battery life and keep the battery fully serviceable.
- Clear Analogue Ammeter: The built-in ammeter continuously shows the current flowing into the battery and gives you visual control over the charging process. Watching the ammeter reading lets you judge charging progress and make a first assessment of the battery condition (for example, a sharp drop in current may indicate a full charge or a problem with the battery). For a professional it is a useful diagnostic aid and a confirmation that the unit is working properly.
- Solid and Durable Telwin Construction: The ALPINE 15 has a metal housing and uses proven components, a hallmark of the Telwin brand. The traditional transformer design is less vulnerable to damage in harsh workshop conditions than more delicate electronic chargers. This means long-term reliability, fewer breakdowns and the confidence that the unit will cope with heavy use for many years, which makes it a cost-effective investment.
