The NightStick Replacement Battery for 5560 Series LED Lights is a genuine lithium-ion power cell engineered to keep your cap lamp operational during extended night operations on the water. Designed as a direct replacement for the XPR-5560 and XPR-5561 models, this battery delivers 2600mAh capacity at 9.62W output—the specified power profile these professional-grade lights require for consistent brightness and runtime in demanding marine environments.
Lithium-ion chemistry eliminates the recharge memory effect that plagued older NiCad batteries, meaning you can top off the battery at any state of charge without degradation. This is critical for field users who charge opportunistically between trips rather than on a fixed schedule. The 2600mAh lithium-ion cell maintains voltage stability throughout its discharge curve, ensuring your lamp doesn't dim as the battery drains—essential when identifying markers, reading navigational equipment, or conducting safety inspections in low-light conditions. Bayco Products backs this battery with a 2-year limited warranty.
This battery is purpose-built for commercial fishermen, coast guard personnel, marine surveyors, and serious recreational anglers who rely on helmet-mounted or cap-mounted lighting systems during night operations. Whether you're conducting pre-dawn offshore runs, working night shifts on deck, or need reliable backup illumination for safety-critical tasks, having a spare battery eliminates downtime and ensures your primary light remains deployment-ready. The compact form factor (0.85 × 0.85 × 3 inches) fits the standard NightStick 5560-series mount without modification.
