When I got my new/replacment battery back 2.5 years ago Honda told me it's a new one. I'm now pretty sure it was new because I never ever had a problem with it since its install and all subpacks are well balanced (within 0.05 V). $2000 or £1800 are the price I've paid for mine as well. It's well worth it.
