Best Logitech mouse is a the G700s. Wireless&#x2F;wired hybrid with a NiMH low-self-discharge AA battery included.<p>When it runs low, you either plug the mouse in to charge from USB (also switches data over to the slightly more reliable wired connection), or you swap in a fresh battery and toss the dead one in a separate charger.<p>If your AA battery has too much permanent wear, get a new one. No warranty voiding necessary.
