One of the obvious benefits from using these tiny new netbook PCs is taking them to the road. While travelling, there are two key variables that often go against to each other: the battery life and the weight. I have been experimenting with several different batteries in the Acer Aspire One, and at this time I’d recommend going for the most powerful battery available — the weight gain is not (at least for me) significant enough to outweight the increased lifespan. Particularly on travels with long working days, often with rare access to a power plug, a battery that can go on for the entire day is a true gift.
Here are some shots, featuring the original, 2400 mAh battery shipping with the AA1 (at least those Linux/Linpus editions we are using here), then the white 5200 mAh 6-cell battery, and finally the 6600 mAh ‘extended battery’ (the big blue one). The last one is my current choice, even while the quality of production is not the same as in the official Acer batteries (it carries the brand label of ‘Cameron Sino‘, never heard of them before; it is made in China). I got mine through eBay from merchant named ‘GPS For LESS Ltd‘, operating from the UK (nice, quick service).
It will be interesting to see what is the actual use time for these. According to my experience, the original battery can only handle 2-3 hours of regular use, the 5200 mAh version is much better and carries on c. 5-6 hours, depending on how much you will be consuming electricity. The 6600 mAh pack should thus do at least 6-7 hours, maybe even more, but I still need to test it out in the real life, I got it in mail only today.
