exactly. If it is doable to put a battery in a laptop, why not have an option to put a small battery in a desktop. I would pay for that. ( figuerres, there are not problems shipping laptops with connected batteries. )
btw, I lost power last week and today. IE both times lost stuff. Where I lost my IE most popular sites, had to reenter passwords.
not my rules, talk to the shipping folks ... also moving companies have that rule.
I do not know if Li-ION is any safer than the UPS type batteries and I do wonder if they might start using Li type in a ups or if for some reason the old kind are better for a UPS ??
