Thanks for doing this. I heard that these are one of the easier swaps compared to other hybrids. I have been looking at a 10 to 12 mkz hybrid and this made me feel better going into a possible hybrid purchase.
Over time they die out (similar to phone batteries dying over time and not holding a charge as long) Mine recently started acting up and I can’t take it out of town anymore so I’m looking to do a replacement myself to get her running at full strength again.
