Disconnect Battery Power on PB

[mmills]

I'm going to be working on installing the BoostAuto wireless charger this weekend and the install instructions mention to disconnect the battery before disconnecting a few connectors in the dash assembly to prevent any error codes from being logged and having to be cleared. This got me thinking that I know how to disconnect battery power for a regular vehicle that does not have a hybrid system, but I have no clue how to disconnect on a Powerboost.

Will disconnecting just the battery in the engine compartment suffice or will their still be power due to the hybrid system? Do I also need to disconnect the negative terminal to the battery under the rear passenger seat?

Thanks to any that can help me understand this better.

Just made a post on easily removing the aux battery from the truck. PB has 2 batteries and the under-hood alone isn't enough. Aux batt disconnect is in passenger side kick panel.

Disconnecting that cable is easier / safer than going for the aux batt itself. If you decide to go for aux batt, wear gloves to remove that cover as it can be a pain and when it does finally open you might get the fingers on the seat frame.

Thank you for the info. So to clarify disconnecting the negative on the under-hood battery and disconnecting this connector will allow me to deenergize the system and not cause any fault codes?

I'd disconnect the aux batt and remove the positive from the batt under-hood. Just remove it and place a shop towel between the terminal and the batt while it rests on it.
