I have two old 8 slot plus 9v duracell NiMH chargers. I have owned and used these chargers a lot for well over 10, probably closer to 15 years and they still work and charge AA, AAA, C, D and 9v batteries as well as they did when new.
I keep thinking maybe I should replace them, not because I want better because as far as I am concerned they work perfectly, but from a safety aspect due to their age.
Is there any merit to that argument or is it a case of if it ain't broke don't fix it (or replace it in this case) as these chargers have proven their worth having charged batteries hundreds maybe thousands of times without problem.
