Lighted nocks typically last 30-45 hours.
The lifespan of a lighted nock depends on usage and battery quality. Most lighted nocks utilize button cell batteries and offer 30 to 45 hours of illumination. Frequent use, cold temperatures, and lower quality batteries will reduce this time. Replacement batteries are readily available.
Factors Affecting Lighted Nock Duration
- Battery Type: Lithium batteries generally last longer than silver oxide.
- Usage Frequency: Each draw and flight consumes power.
- Temperature: Cold weather significantly reduces battery performance.
- Nock Quality: Better-made nocks may have more efficient circuits.
Extending Lighted Nock Life
- Turn off nocks immediately after use if they have a switch.
- Store nocks in a warm, dry place.
- Replace batteries proactively, even if the light isn't completely dim.
- Consider purchasing nocks with auto-off features.
Battery Replacement vs. Nock Replacement
| Method | Cost (Approximate) | Duration of Benefit |
|---|---|---|
| Replacing Batteries | $5 - $15 per pack of batteries | 30-45 hours of light |
| Purchasing New Lighted Nocks | $20 - $50 per nock (set of 3) | 30-45 hours of light (until battery dies, then battery replacement needed) |
| Using Rechargeable Lighted Nocks | $40 - $80 per nock (initial cost) | Hundreds of charge cycles (potentially years) |
Checking Battery Life
Most lighted nocks will visibly dim as the battery loses power. Some models may have a test function. It's good practice to test nocks before each use, especially if they haven't been used recently. Always carry spare batteries.
