Battery Charger
This battery charger also provides a 12 volt output for testing components that I have found to be an excellent tool - you don't have to find a car battery to do the job. An excellent versatile product reasonably priced

Uno dei migliori caricabatterie non professionali
Prima di acquistare questo modello mi sono informato parecchio. Il primo fatto positivo è la scelta dell'amperaggio: 0.8A per le batterie da moto, 3.8 per quelle da auto. Ci sono poi una serie di programmi per il recupero delle vecchie batterie (ricarica accumulatoti che sono scesi fino a 2V), per la desolfatazione e per il mantenimento di carica. Il prodotto è corredato da comodissimi attacchi rapidi che possono essere lasciati sulla batteria per un mantenimento molto semplice. Non costa poco, ma se durerà nel tempo sarà di sicuro un ottimo acquisto.

You won’t go wrong with these chargers
C- Tek are well made chargers and work very well. I have now several of them in different locations. Some for long term trickle charge and others more powerful to charge batteries in an emergency. Highly recommended.
