Ray,IN Posted August 27, 2015 Report Share Posted August 27, 2015 I have a Xantrex RS 2000 inverter/charger owners manual. here are its specifications. I've read here and on other RVing forums, the float charge rate should be 13.3 V. The specifications for my unit state the float charge voltage is 13.5, which is the boiling point for electrolyte. My Exide 31MDC batteries failed after 14 months. At that time the float voltage was 13.6 and an alarm sounded because the batteries were at 130*F. Exide/Camping World just warrantied my failed batteries at no charge. Now to my questions, is there any way to adjust the float voltage in the RS 2000? The owners manual gives no indication it is adjustable. Next question, the RS 2000 has a 3-stage charge and a 2-stage charge. The 3-stage has a float charge, the 2-stage does not, as explained on page B5. Should I change to the 2-stage setting? Next question, which shows my ignorance about this subject. When setting the battery amperage, should it be set for total of all 3 batteries or only one? They each have a 200AH rating. Next is charge rate. The RS 2000 has a bulk charge rate of 100A, is this too much for this battery size? It has the capability to reduce this by a percentage. Right now I have it reduced to 50%, because I remember reading charge rate should be a max. of 10% of battery capacity. Link to comment Share on other sites More sharing options...
