Yes. That's what this listing is for: a fresh set of batteries for the DNO Tripod Lighted QD top mount when the light gets dim or quits. Swap them before the season starts and carry a spare set, because cold nights pull batteries down faster than you'd expect.
The part on top is usually called the head, or the top plate or top mount when it is a flat attachment point. The DNO Tripod Lighted QD top mount sits in that spot, and these batteries power its light. Keep a spare set in your pack, because cold nights drain batteries faster.
