Not all batteries are created equal
While there are few computers powered by off-the-shelf batteries, they are unavoidable when it comes to wireless mice and keyboards, MP3 players and all manner of other gadgets.
The key consideration for me is how long the battery will last, so I'm a bit obessive when it comes to reading the capacity, normally expressed as mAh (milli amp hours). It's not just AAA batteries but I tend to check on fixed batteries as well. It all stems for really needing a mobile phone only to find that the battery had run out.
There's a fascinating article about batteries to be found over at Coding Horror. Fascinating but doesn't do anything for my ego as I've been oversimplifying the decision.
It appears that it's not just about capacity but about how fast the battery will discharge. So you can have a higher capacity battery that runs out faster than a lower capacity one. And of course there is also the consumption of the device itself, which is why a single AAA lasts longer in an MP3 player than a huge notebook battery.
It also sounds like it's time for me to find a better battery charger.
