Mikey B Posted January 11, 2009 Report Posted January 11, 2009 My Orkney 520 has dual leisure batteries and a rotary switch with No1 used as a starter and No2 for the radio etc. Because I only use her in Poole bay or the Harbour I found the batteries where not up to full charge due to the run times and output of the motor alternator. Motor alternator only produces 12/15 a/hr @6000 rpm. I now use a CTEK 7000 XS Multi charger 14 / 224 to keep my dual batteries fully charged. On its maintenance cycle I can leave it plugged in permanently while ashore. Having access to a permanent 240volt supply ashore I just plug it in after a day out and it maintains a pair of fully charged batteries. CTEK recommend a routine check on fluid levels form time to time - but as yet I have not needed to top the batteries up and both batteries are as good as new. Mikey B Quote
