UPS Issue

Based on a thread in this forum and posts by several users, I purchased the Cyberpower CP750LCD UPS to protect my TiVo in the living room and another to protect my networking gear in my office. I'm mostly satisfied with the UPSes. However one thing perplexes me, the fine print on the bottom says the batteries are NOT user replaceable, and the screw that seems to be holding the battery cover closed is, I believe, a tiny torx screw with a raised element in the middle of a star shaped hole Has anyone replaced the batteries in this UPS? and if so, how? Where can one get the proper screwdriver for this?



Thank you.
