If your house bank(("auxilliary battery")) is dead and nothing is working we have both short-term and long-term problems. Let's start with the short term issues. | If your [[electrical:12v:intro#storing_power|house bank]](("auxilliary battery")) is dead and nothing is working we have both short-term and long-term problems.

- 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 charging methods are configured to meet your battery manufacturer's [[electrical:solar:charge_controller_setpoints|charging specs]] - voltages, durations, and min/max current |
| - if charging by solar ensure the panels are [[electrical:solar:shading|completely unshaded]] |
- 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 | - 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 |

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. | Yes, your battery may be toast but there is no use replacing it until you get the underlying issues fixed.

| If you know the battery is "injured" you might choose to [[electrical:severe_battery_use|run it into the ground]] before replacing it, or while sourcing a replacement. |
