Re: Help for hv battery
The good news is that the full process isn't required. One can simply:
Put a 10A charger on the 12V.
Fully charge the 12V.
Leave 10A charger on the 12V
Remove the safety plug
Remove the battery cover.
Remove the cover over the bolts connecting the relay to the main terminal.
Attach charge leads to the terminal bolts, (-) on passenger side.
Replace safety plug.
Hit jump start, wait for flash.
Ignition on (do not start).
Clear codes with Forscan
Cycle ignition when instructed to do so.
Energize charger.
Since the car will see a 300V+ at the battery, it will energize the relay and connect the battery to the car once ignition is on. As long as the 12V can power the ignition, one should get a net charge. One can use Forscan to monitor the progress.
Recommend 1-2 hours. Once the chemistry has been reactivated with input, the jump starter should function normally.

I want to try that method to reactivate the battery. I got the symptoms you described when I hit the button then car starts for 3 sec and dies. I would like to know how the light on the button should be if I follow the process please.
Also am I required to leave the ignition on for 1-2 hours?
