No not reverse spam, nor a competitor.
I am an engineer in the construction industry - well, actually now a business development manager. The laptop I refer to is for home use, and the company I work for are one of the leaders in control systems for smoke control. We use rechargeable batteries by the thousand, all be it of the size and type used in motobikes and cars - sealed lead acid that we buy in and build into our control panels. These last for 5 years by the way and cost a fraction of a laptop battery and are pretty low tech compared to laptop batteries I guess.
Prior to this I was an automotive engineer.
Sorry to disappoint you.
No I posted because I am furious, and like many engineers can be a bit obsessive, and this one really got my goat!
