- 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 ?
