This should be the 2032.

This optic uses a single 2032 coin battery. "The TRS-26 is powered by 1 CR2032 battery and sets the industry standard with more than 50,000 hours of battery life." It was my pleasure to assist you.

Tyler, It takes one 2032 disc battery. Great choice for a value quality red dot. Long battery life and nice features.Plus has aimpoint mount option plus standard pic rail mount option.
