Do dual power calculators need battery changes?

QueAndAy asked:
Does a dual power calculator (that is, calculator that runs on solar and a battery backup for dim lighting conditions) ever need the battery changed? Or does the solar cell charge the battery to eliminate the need for a battery change? I avoided dual power calculators in the past as I don’t like to change the battery if I don’t have to. Thanks.
