After 15 or so years the nicad battery in our 30y.o. portable phone has chucked it in (it's only ever had one replacement). The current options are nicad or Ni-MH.
Which way should I go?
If Ni-MH how long is it likely to last?
I only get around 4 years between replacements with a Samsung mobile which presumably has a smart charger, hence the question.
