I have a wireless computer mouse I purchased some years ago, a Logitech MX 700. The rechargeable batteries for the mouse are nearing the end of their lifespan–they won’t hold a charge for more than a few days. Worse, the blinking red dead-battery indicator on the top of my mouse blinks constantly, which is annoying. The buttons on the mouse don’t quite work the way they used to and the paint has worn off the plastic wherever it touched my hand. The mouse lasted six years, a respectable time for a computer mouse, but it’s time for it to crawl off to that place all mice go to die.
Even though the mouse isn’t rechargeable, three years between battery replacements is a huge improvement.
