Why does my new wireless mouse not work with brand new energizer batteries? (triple aaa)?
It worked when I took the batteries out of the remote control and used them, and they are so not new.

Make sure you installed them properly
The flat end of the battery (Negative) will go to next to the spring.

Brand new batteries can be defective, or you can have them put in backwards, or you may need to reboot the computer and/or reinsert the USB dongle for the mouse.
