 ====== How to handle a dead house battery ======
-If your house bank ("auxilliary battery") is dead (nothing is working) we have both short-term and long-term problems.  Let's start with the short term issues.

+===== fix the underlying problem =====
+  - ensure all charging methods are configured to meet your battery manufacturer's [[electrical:solar:charge_controller_setpoints|charging specs]] - voltages, durations, and min/max current
+  - ensure all connections are good:  battery connections, solar panel connections, grounds((bad grounds can cause problems with alternator charging in particular since the chassis is often used as the negative return)), etc
+  - get your [[electrical:12v:alt_and_solar|power production]] and [[electrical:solar:rationing|power use]] ratio under control.   Make sure you are making power whenever you can.
+===== replace any damaged components =====
+Yes, your battery may be toast but there is no use replacing it until you get the underlying issues fixed.  If you replace the battery with the same problems [[electrical:batterycide|it will be murdered]], too.
+===== don't beat yourself up =====
+Now that the ship is righted again, take solace in the fact that many before you have made these same mistakes before.  Vanliving is doing, and breaking stuff, and fixing it.
