@ d3vy "That said, their AA rechargeable batteries were always good value - I might go and stock up!"
Did I miss a <sarc> tag? Their Rechargeables (IME, YMMV) were a bunch of crap which was unfortunate as it was one of the few things I went in there for. I bought loads of them over the years but stopped when the occasional failure became a routine thing. I found they lasted perhaps 4-6 years from purchase but no more than 100 or so charge cycles (if that!). You might think 4-6 years is about right for a NiMH but I have Uniross rechargeables from about 2000 (yes 18 years old) still working in daily use and I'm sure they've long exceeded their specified limit of 1000 cycles.
