Battery performance tips

Your mouse enters standby mode to conserve power when not in use. Here are some other ways you can help extend the battery life:

• Use only alkaline batteries. Non-alkaline batteries (such as NiMH,or NiCd) operate at a lower voltage and may affect the battery life.
• Avoid using your mouse on dark or transparent surfaces, such as glass. These surfaces cause the sensor to use more power.
• Don't mix old and new batteries or batteries of different brands.
• Make sure replacement batteries are new and within the manufacturer's expiration date.
