Some early users reported that battery life was abysmal, though—a mere 30 days or so. This weakness may be one of the reasons Apple changed the battery type used in the Magic Mouse 2 to an internal rechargeable lithium-ion battery. If you're still rocking the original, though, there's a simple solution. Sources of Magic Mouse Battery Drain Apple, Inc. If you're experiencing abnormal battery drain, it's quite possible the batteries, and not the mouse, are the culprit. In most cases, the Magic Mouse comes with Energizer batteries, which are a well-respected brand. But it's difficult to know how long they've been on the shelf before being used. It's likely that new, fresh batteries will last longer than the 30 days some users were getting out of the initial batch. Of course, battery life also depends on usage. The Magic Mouse is supposed to go into hibernation when it detects a lack of use, which helps extend battery life. Turning the Magic Mouse off manually when you're done using it, with the switch on the mouse's belly, should help push battery life a little further. Switch to Rechargeable Batteries Another option to get the most life out of the Magic Mouse is to replace the default batteries with either lithium-ion AA or rechargeable nickel metal hydride batteries. Both should provide longer life. The NiMH batteries have the added benefit of being rechargeable. If you decide to go the rechargeable route, look for NiMH AAs with a 2900 milliampere-hour rating or better. Many of the bubble-packed, brand-name rechargeables you find in the checkout aisle of your local hardware or grocery store have a 2300 to 2500 mAh rating. While they work, they won't have as much staying power, and you'll find yourself recharging them fairly often. The 2900 mAh batteries are sometimes referred to as high-capacity batteries. Lithium AAs are also available in various Mah ratings, and once again the 2900 mAh rating is a good value to look for. Lithium batteries have a much longer life than standard alkaline AAs. They also last longer than the NiMH batteries do on a single charge, but they're not rechargeable. Lithium AAs do have a downside; they're a bit expensive when compared to standard AA batteries.
