Well, I have to replace the batteries for my Apple Wireless Mighty Mouse (Bluetooth).


[sdp=79055]In this post[/sdp], I got my iMac on 1st November.

From following picture, Apple provides two Energizer e2 Lithium batteries for Wireless Mighty Mouse.



Yesterday I received following message:


And this is from the System Preferences,


I've never bought any Lithium batteries myself. (Duracell Alkaline has been my default choice for more than a decade.)

Apple provides good quality batteries with it's products. That certainly is a nice change from the usual behaviour of the companies including the cheapest possible batteries.

I think you'd find those Lithium batteries will last a lot longer in your mouse than regular Alkaline batteries.

In my experience at least, Energizer batteries have always lasted considerably longer than Duracell batteries.

Well, in 2001, I bought the then state-of-art Logitech Cordless MouseMan Optical mouse. It was the first wireless and optical in the market! The two Duracell batteries lasted longer then on Wireless Mighty Mouse, they lasted about two months.

Before you jump into conclusion:
Logitech Cordless MouseMan Optical mouse is RF (radio frequency) and uses optical tracking technology (with LED lighting).
The Apple Wireless Mighty Mouse uses Bluetooth and Laser tracking technology.

And I have to admit that I never switch off the mouse to save battery, and I use a black mouse pad, which might require more energy for tracking due to the darkness. (It is said using a light colour mouse pad but not shining one for best result.)

In my experience at least, Energizer batteries have always lasted considerably longer than Duracell batteries.

Which Energizer batteries do you use? The regular "alkaline" batteries? or the "lithium" batteries or other expensive ones?

I use Radio Shack rechargables in my wireless devices. They might not last as long as alkaline batteries, since they wanted a fortune for rechargable lithium batteries, but they pay for themselves quickly.

I've only used lithium batteries twice; they were Energizer camera batteries. Those lasted about three months each, but the price of lithium didn't justify buying them again: $15 for just one, and I can only imagine how expensive it'd be to buy rechargables.

Just happened to see the catalogue of Officeworks... the Energizer E2 Lithium AA 4 pack is priced at AU$ 19.98, that's about AU$5 for each battery... gee, that's expensive!

That's why I still use a mix of the cheaper NiCd, NiMH, and lead-acid batteries.

Can you post a picture of this? I'd like to see how you fit your (car / motorcycle?) battery into the mouse. Or is the mouse harnessed to a battery cart?

Nah, I don't use then in my mice; my mice are all wired (one is serial and the other two are PS/2). I actually use them in a video camera, and they look like this:



That's a penny on the right, for comparison. It's a 12-volt battery, much like most car batteries, but only two amps, which wouldn't get anywhere close to starting a car. Just for the record books these take two hours to charge and two hours to discharge.

Drat! I hate it when people point up my ignorance. Here I thought that you were being facetious in tossing in the lead-acid tag on the list of battery technologies, just to see if anyone would notice.

Thanks for the education. Now, let's see ... connect up about 300 of these puppies in series-parallel and hook them to a suitable DC motor - through a suitable controller, of course - and one could have a nifty no-pollution run-about short range vehicle. Good project for a university engineering class, no? How does the name Mozilla Motors sound to you?

Nah, I'm known for having a ton of weird old stuff. I don't think the battery charger for these takes anything other than lead-acid batteries, and at that, I never found anything but these (Radio Shack is the only place that sells them to the best of my knowledge). Would you believe me if I said I had an AT keyboard or a 70MB hard drive?

I've already got five of 'em. 295 more to go, which translates to $5900 -- they're $20 each. You'd need a pretty big motor for 3600 DC volts of power though; might as well make a small supersonic jet engine if you can get enough starting amps to power something like that.

Well in that case how about Mozilla Airlines?

Finally, the batteries on my Apple Wireless Keyboard went flat today after a few days of law battery warning. It is the first time I replace them since I started using the Apple Wireless Keyboard on 1st November 2006. That's about 4 1/2 months, which is not that bad (compared to two batteries for Apple Wireless Mighty Mouse).

How often do I use it? I typed quite a bit every day. The batteries were as show in the first post of this thread, 4 Energizer e2 batteries from Apple.

The replacement batteries are the Duracell alkalines, and I will track down on how long they last.

Just for the record, I never bothered to switch off the keyboard at night, which can be simply done. (Or perhaps I should.)

I also replace the batteries for Wireless Mighty Mouse today, (2 Energizer Max), it is the 3rd or 4th time I replace batteries for Wireless Mighty Mouse.

BTW, Apple Wireless Mighty Mouse can operate on only one single battery... I might try that.

Hendikins said his wireless keyboard only uses 2 normal AA batteries, and the batteries last for a year or so. For last set of batteries they lasted 15 months.

His wireless keyboard is RF, not Bluetooth.
