Lumenok RBS Replacement Battery for Lighted Bolt Nock 2-Pack

Keep your Lumenok crossbow lighted nocks firing bright with the RBS Replacement Battery 2-Pack. Each pack contains two BR-425 replacement batteries designed specifically for Lumenok bolt-end lighted nocks, the crossbow versions of the popular lighted nock system.

These batteries deliver approximately 40 hours of on-time brightness and carry an approximate 4-year shelf life, giving you reliable power to repower spent nocks in the field. The RBS is also compatible with the Lumenok Signature, GT, X, and H Series arrow nocks, where swapping in the BR-425 reduces the overall weight of the nock by about 4 grains for archers looking to tune arrow weight.

Sold as a 2-pack so you can keep spares on hand or replace multiple batteries at once. The Lumenok RBS is the factory-recommended replacement battery for keeping your lighted nocks performing at their brightest.
