As someone quite experienced in the electronics, and battery technology
field, DO NOT TRY THIS!!! It is not worth the risk. I would never trust
such a battery in my precious Newtons :P
Seriously, the risks of leakage and/or fire through a breakdown in
internal chemistry/battery wall are real in "recharged" alkalines/zinc
chlorides. Yes, they can actually explode, even if you don't believe
the warning stickers. Do yourself a favour and invest in some good high
capacity NiMH's and a good charger, and it will pay off over time.

Thinking of what's best for your precious Newt,
