How about a charger for Alkaline cells ? I've seen one in a UK hobby magazine
using a system of periodic charge/discharge at 50Hz, but the charge time 
figures they presented didn't make sense.
So I built a version that I was happier with, but performance seems poor 
(long charge time, recharged cells don't hold their charge well).

Has anyone here got figures for the optimum charge rates for 
'non-rechargeable' cells in various sizes, and from various manufacturers ?

UK alkalines are normally marked 'do not recharge' with dire warnings
regarding leaks and explosions. Since some other countries (Japan ?) 
apparently positively encourage recharging, I'm dubious about these
warnings : they might be sheer protectionism, or a fear of product
liability. Or they might use inferior products in this country, since
they seem to be able to get away with it.
Are similar warnings printed in other countries ?
