Choosing the right batteries is essential to keep mice and keyboards alive for a long time

It’s no mystery that Apple’s expensive peripherals use a lot of power, forcing us to replace / recharge the batteries on a weekly basis. Here’s one way to avoid doing this so often.

Some of you may have already noticed this, but in case you’re still wondering why your Magic Mouse is such a power-hungry vampire, check the voltage on your batteries. If you’re using rechargeable batteries, chances are they’re 1.2V each.

Most NiMH rechargeables, including the ones Apple sells, output 1.2 volts. Normal (non-rechargeable) batteries output 1.5 volts. Magic Mice and Apple Wireless Keyboards use two AA batteries, which means that instead of getting 3 volts, they’re only getting 2.4V.

In my tests I’ve found that both Magic Mouse and the Apple Wireless Keyboard last much longer when used with normal (non-rechargeable) 1.5V batteries.

I’m no expert but the difference is obvious: one week tops with rechargeables (tested using multiple pairs of NiMH batteries); two to three weeks on normal alkaline batteries.

Don’t take my word for it. See for yourself. Also, I’d be glad to hear what your mileage is.
