HVB SOH percentage increase over time.
I wanted to update the forum on my 2023 XLT SR that was processed as a Ford buyback at 34,000 miles.
I had posted here originally on April 03, 2026.
I took possession of my truck Feb 01, 2026.
The battery was replaced under warranty 11.5 months ago (so ~ April 15th, 2025). This is when it was processed as a Ford buyback.
When I took possession, the HVB SOH was showing at 90.5%. I attributed this to sitting at a low state of charge, as a new battery pack, and then coming from Florida to Northern IL in the depths of winter.
Over time, the SOH crept up, 0.5% increments.
On April 03, 2026, the SOH, after several 100% AC charge session was showing at 96.5%.
Today, May 08, 2026, the SOH now shows at 98%.
I had assumed this would happen, as my Module variation at full 100% charge has always shown as 0.002v; which is about as perfect as one could expect.
I believe that I will see 99% this summer; or maybe 99.5% or possibly 100%.
I will update the forum, once that happens.
