fzeuner Report post Posted January 9, 2019 Hi All, I want to equalize my house batteries. they are tied to the engine start batteries during the normal charging process. Should I leave them tied together or isolate the start batteries during the equalization process. The engine start batteries are Alliance batteries. Appreciate any advise.

manholt Report post Posted January 9, 2019 Acid, AGM, or Ion? Brand is not important. My 2 start & 8 house are all AGM's by NAPA. Share this post Link to post Share on other sites

rayin Report post Posted January 10, 2019 I'll throw in the way my Xantrex RS2000 equalize works. Both battery banks are connected for charging via a BIRD relay. I set the inverter/charger to equalize via the display panel, it asks " are you sure?", I affirm the equalize. Everything is automatic from that point. It first insures the batteries are at 100% charge, the goes to equalize mode and tests the batteries for actually needing the equalize. Sometimes it completes a complete cycle sometimes only 1 hr, once in a while it says equalizing not needed and terminates the process. Point is, all batteries are included in the process unless the BIRD automatically disconnects the two banks. Share this post Link to post Share on other sites
dickandlois Report post Posted January 10, 2019 Ray, Do you need to setup the charger to allow for the current load of the chassis batteries when in equalizing mode? Personal never used the setting, keep checking them with a hydrometer and if one cell starts to drop; just replace the week one. Considering going to AGM. Rich.
