Schumacher SEM-1562A 1.5 Amp Speed Charge Maintainer Well worth the price...does exactly what it is suppose to do. (Update) After using this charger less than 5 mos. to maintain my R.V., which is seldom driven, I have found that, because of the charger failing to cycle back to the charge mode properly, the battery that it was hooked to was stone dead. Now, I'll do some research to find out the annoying process of returning the charger for warranty. (Update) I have contacted the manufacturer, Schumacher, concerning the failure of this charger but after 3 weeks, have received no response and it doesn't look like I am going to. So, I guess I'll just take the loss of making a bad choice and trash it. BTW, I am using two Chicago Electric on Board chargers, one on my Jeep and the other on my Mercury Sable. Both are giving very good service and are less expensive than the Schumacher or the Battery Tender.
