The Rival 3 Wireless uses two AAA batteries. When the battery life indicator (often visible through the scroll wheel's RGB lighting or via SteelSeries Engine software) suggests low power, replace both batteries with new AAA alkaline or rechargeable batteries. Refer to the battery installation steps in the Setup section.
