One rule of thumb is that if the UPS unit does NOT have a reasonably obvious hatch through which one can replace the battery - it's not intended to be replaceable. This can be difficult to determine through packaging, of course. For myself - after multiple bad experiences with other brands, I don't buy anything but APC these days. Even their small 350VA units have replaceable batteries, they make it fairly easy to order replacements and the replacement order generally includes recycling the old one. They've clearly faced up to the fact that sealed lead-acid batteries are a key component of their business and put in the effort to mitigate any environmental impact.
As for Win7's complaint - check the USB "mode" in the BIOS. Usually it's possible to "demote" the USB controller to a legacy mode for compatibility with older OSes and perhaps your motherboard defaults to that with the result that Win7 thinks it needs a different driver.
