Palo Alto, Calif. - Hewlett-Packard today announced several PC accessories, including a Wi-Fi mouse.

The Wi-Fi Mobile Mouse, $49, directly connects to the computer without the need for a USB dongle, the company said. The mouse has five customizable buttons that can be set to handle certain shortcuts and a scroll wheel. The battery will last about nine months, twice what is normally received from a Bluetooth version, the company said.

Other new accessories use HP's Link-5 technology. This allows users to connect up to five HP compatible PC accessories with one receiver, alleviating the need to fill up a computer's USB ports.

The devices have an intelligent sleep mode to help conserve batter life and do not require the installation of drivers or software.

The Link-5 products are the:

• HP Wireless Mini Keyboard, now shipping for $59;

• HP Wireless Elite v2 Keyboard, shipping in July for $49;
• HP Wireless Optical Comfort Mouse, shipping in June for $29;
