This is one excellent product! We have to keep 8 12 volt batteries ready for our own RV and our backups that we use when out on a service call. You'd be surprised at the number of clients that call us because their 12 volt system isn't working. Check their battery and it's deader than a door nail. We hook up one of our well kept batteries and voila folks!
We obviously bought 2 of the chargers and wouldn't be without them.. ever!
They don't hit the hydro hard which is great as we leave them on all the time as needed.
