Some mice, such as the Logitech V450 848 nm laser mouse, are capable of functioning on two AA batteries for a full year, due to the low power requirements of the infrared laser.
Osad optilised hiired, nagu nt V450 848 nm laserhiir, töötavad kahe AA-patarei pealt terve aasta, kuna infrapuna laser vajab töötamiseks vähe energiat.
