Anyone have any recommendations or experience using battery tenders? My backup generator for the house is 36 volts but doesn't have provisions for an alternator to keep the batteries charged . Do the tenders run all the time or only when the batteries need to be "topped off"? Are they a good idea? Thanks, Jim.
