Tenergy Centura LSD NiMH, 12D: $60, 24AA: $32 (newegg)

Price is now up to $89 for a dozen cells — but — only six months’ warranty, for a product that’s advertised as holding most of its charge for well over a year?

How does that work?

I charged mine at the end of September of last year, and just used them this week, they were at 1.28 volts, and worked fine.
