Battery chargers have been a repair item for about 15 years now. We're currently repairing the Eltek Multichargers for auto dealerships accross Canada. We are also repairing and maintaining marine chargers for 32V boats. We've repaired a number of Davidson, La Marche and Intercontinental chargers and inverters in recent years. If you have one of these older units we're the place to call when it needs repair. In our opinion nothing on the market today is as well built as these older units, there's a reason it's still in the boat 20 years later.
