You're probably right and thanks for the advice, but this is for on-site storage I'm considering for my parents. They live in a country that takes me about 24h to fly to, with daily power outages, and while I'm sure they could do it if they wanted to, they're rather averse to the idea of doing any wiring work. A user-replaceable battery that can be replaced in the way that an older Thinkpad battery can would be nice. I'm looking at the options suggested [here](https://news.ycombinator.com/item?id=10831796 https://news.ycombinator.com/item?id=10831796) and [here](https://news.ycombinator.com/item?id=10831721 https://news.ycombinator.com/item?id=10831721), but I'm having a hard time finding APC battery availability in India.
