I do replace them every year or so to avoid leakage.

"Replace" or "recharge" every year?

The whole reason I got rechargeable N's is so that I would never need to worry about leakage damaging my 41. I don't know that I have ever seen rechargeable batteries leak. I've got rechargeable batteries that are 12 years old in my class set of calculators at school.
