Hey everyone,

I’m looking for some advice on my 2022 Accord Hybrid and its high-voltage (HV) battery.

Here’s the background:

• I purchased the car wrecked at auction. It was running fine when I received it.
• During welding (with the 12V battery disconnected), the process ended up frying the VSA/ABS modulator. That issue has already been fixed.
• While chasing down that repair, the HV battery fully discharged.
• Where I am now:
• Dealer quoted ~$4,900 for a new HV battery pack.
• I found a used pack at LKQ for ~$800 from a wrecked Accord Hybrid.
• I understand the physical swap is possible with the proper safety steps, but I’m not sure if a replacement pack will be plug-and-play or if it requires i-HDS initialization/programming to get the car to recognize it.
• I’ve looked into Honda Techinfo (i-HDS) subscriptions and know I’d need a Windows laptop + J2534 pass-thru device to do this myself, but I’m weighing that cost vs. having a dealer/independent shop handle the programming after I install the pack.

Questions for the community:

• Has anyone here successfully installed a used HV battery pack in a 10th-gen Accord Hybrid?
• Did the replacement work right away, or did you need dealer/i-HDS initialization to clear codes?
• Any recommendations on J2534 devices that actually work well with i-HDS for hybrid battery work?
• For those who’ve tried salvage packs, how reliable have they been? Anything I should check before installing?
• In your experience, is it better to invest in the i-HDS setup or just do the swap and tow it to a shop/dealer for the final programming?
• Is there any chance my existing HV battery can be recovered or reconditioned instead of swapping? The dealer insists it can’t be recharged once it’s fully discharged — is that accurate, or have people seen recovery done?

Appreciate any first-hand experiences, tips, or warnings — I’d rather learn from others who’ve already been down this road.

Thanks in advance!

 

Junk yards dont keep the batteries charged. Buying one from a junk yard is a real crap shoot and not worth the risk/work involved ,IMO.

As for replacing the battery, these vehicles are still under warranty, so I doubt anyone has any real experience with the process.
