Discover the Advanced Features of the TELWIN ALPINE 18 BOOST 230V 12-24V
Charging Power and Versatility: Energy for Every Battery
The Telwin Alpine 18 Boost is designed for maximum flexibility and efficiency. Switchable between 12V and 24V, it suits many kinds of vehicles and machines, from cars through vans and light trucks to heavy agricultural and construction equipment. The unit offers two charging current settings, so you can match the parameters precisely to the capacity and condition of the battery and give it the right conditions for a long service life.
Effective charging currents (14A for 12V and 8A for 24V) ensure relatively quick recharging of batteries with reference capacities from 60 to 115 Ah (12V) and from 30 to 60 Ah (24V). The built-in ammeter lets you monitor the process continuously, giving you full control and the confidence that charging is going as it should. It is a versatile tool that meets the expectations of professional mechanics and demanding private users who look after their batteries.
BOOST Function: Instant Starting in an Emergency
A sudden drop in temperature, lights left on, a long standstill: there are many reasons for a flat battery, and any of them can immobilise a vehicle at the least expected moment. With its integrated BOOST start assist function, the Telwin Alpine 18 Boost becomes your reliable rescue. Simply connect the charger, select the correct voltage and activate BOOST mode to deliver a strong starting current pulse of up to 140A (0V CC) or 80A (1V/EL).
This function is invaluable in professional workshops, transport companies and on farms, where time is money and machine downtime means losses. Instead of wasting time on awkward jump leads from another vehicle, the Alpine 18 Boost lets you start the engine quickly and on your own. That means not only convenience but also greater safety and independence, especially in emergencies and difficult terrain.
Safety and Reliability: the Foundation of Professional Work
For years the Telwin brand has stood for quality and reliability in the industry, and the Alpine 18 Boost charger is no exception. It is fitted with a set of advanced protection features that protect both the user and the connected equipment. Overload protection automatically interrupts operation if the load is too high, preventing damage to the unit. Reverse polarity protection eliminates the risk of serious damage to the battery and charger if the clamps are connected the wrong way round. In addition, protection against a short circuit at the clamps keeps you safe even if the clamps accidentally touch.
The sturdy metal housing withstands mechanical damage and harsh workshop conditions. All components have been carefully selected and tested for long, trouble-free operation. With the Telwin Alpine 18 Boost you can be confident that charging and starting will run smoothly and safely for many years.
