I can verify that the car @Balto revived is still working fine. I’m not even being particularly kind to it! I am using the charge/assist boost controller from @retepsnikrep to increase the assist when pulling a hill on the way to work which is depleting the pack much more than it normally would. I then boost the regen going down the other side to charge it back up.I recently (well somewhat, about 7 months ago now) grabbed a MT that had been sitting, ironically, for 7 years. He parked it for the same reason: an IMA light. I grid charged the pack and did some work to the car, and passed it along to another forum member, who as far as I know, is still driving it without issues.
I implore you to grid charge the pack and at least attempt to revive it. The Honda OEM packs from 7+ years ago were much better built than the ones today. I wouldn't recommend a grid charge, just a top balance.
[Edit]: Furthermore I got a 118k mile CVT car that had been sitting for like 3 years because of an IMA light, and that car I didn't even grid charge, I just disconnected and reconnected the 12v about 10 times and let the car idle until the battery gauge did what is called a 'positive recal'. I then drove it home 450 miles+ about 300 miles around town without an issue. It didn't have registration so I haven't driven it further, but I'm sure the pack is fine. It survived a climb up the Gravevine(a 10% grade out here in SoCal).
