Powerboost 12V Battery State of Charge low

With a hybrid, one expects the 12V battery to be trickle charged off of the hybrid battery, but if one doesn''t drive enough, and leaves the hybrid battery low, then this may not happen. While I''m not up to date on Powerboost issues, the key to keeping the 12V battery charged up is driving, i.e. drives of 30 minutes or longer.

12V Battery Low warning

The following message: Attention: 12V battery low. Please start the engine or switch off the infotainment system. There was also a yellow "12V battery low" warning on the cluster, but forgot to snap a pic of that one. The car was NEVER slow to turn over, or gave me any problems whatsoever starting. The car would charge at 13.3 to 14.6v.

Why is my inverter shutting off due to "battery low voltage"?

Both our standard inverter and hybrid inverter/chargers have low voltage protections. In a hybrid inverter, you may get warning about "battery low voltage" or "battery over-discharge", and in a standard system your charge controller and inverter may show a fault or shut off due to low battery voltage.. This cut-off is designed to happen when the batteries have been discharged …

If the voltage has dropped below 8V, the battery will not communicate via Bluetooth anymore. The Bluetooth module is turned off when the battery terminal voltage drops below 8V or if a cell voltage drops below 2V. You can try to recover the battery by using the below low-voltage recharge procedure.

"Low Battery" Code Every Startup

I tested voltages at startup with a fluke 88V at the batteries. This meter can actually log low, max and avg voltage. After four start cycles the low voltage warning appeared twice. When the warning appeared the low voltage was 10.98 and 11.18, max voltage 14.83 and 14.92, and avg was 14.28 and 13.91 (Avg depends on how long I had the meter on).
