Peak PKC0CV 4/10/20/40 Amp Intelligent Battery Charger

I love this charger. Perfect for my RV having 2 parallel deep discharge batteries. Charging with my on-board gas generator seriously speeds up the charge at the 40 amp rate. While paying $4 for gas I don't want to run the generator unnecessarily with a charger having a slower charge rate.

It works as promised. But the manual is not too clear about how it works. There is no transformer. It's a High Frequency switching power supply and charges by both constant current and constant voltage only near the end. Near the end of charge the microprocessor switches back to constant voltage to top off the battery at a much slower rate.

I set the mode at 40 amps and if the batteries are deeply discharged, it stays steady as a rock at the 40 amps, up until it approaches 90% of the full capacity. Then you can see the charge rate taper off as it slows down the charge until it's full.

I spoke to customer service about the 90 day warranty. They just didn't get around to updating the warranty period to a year. But they have not denied a free exchange to anyone, no matter how long they had it. Of course they want to reserve the right to deny a free exchange if it was abused. IMHO for the money, it's the best in value, rating the performance vs cost.

I would like to buy this but just noticed that the warranty is only 90Days!!! That's it???? Only 90days!!! They must not think much of their product!! Even unreliable Vector VEC 1095 offers 5 Years, last time I checked (I had 6 of those).
