Probably most folks would agree that lead is old tech. NiMH, not so much. NiMH may not have lithium's specific energy, but from what I've read it's inherently safer. It's proven itself reliable and robust, and IMO is still a practical and useful battery chemistry. The problem is that GM / Texaco / Chevron / Cobasys were massively successful in keeping them out of EVs, and by extension, keeping production EVs off the roads for about a decade. I can point to decent AAA and AA size NiMH cells available today, but I don't know have a clue who makes really good D-size or prismatic NiMH, if anyone. I looked at the website you mentioned. I saw no indication of who supplies their cells. If it were a known name, you'd think it would be in large friendly letters on the cover. They could be fine, long-lived cells, or generic Chinese sweatshop cells just good enough to survive their 25,000 mile warranty. I'd be really suprised if you got another 200,000 miles out of them, but who knows? Maybe they're worth a try.
