XP Lithium Battery for WS4, WS5, MI-4, and MI-6 Pinpointers

This XP lithium battery fits both the MI-4 and MI-6 pinpointers. The same battery also powers XP's WS4 and WS5 wireless headphones and XP remote controls, so you can use one spare across multiple accessories. The universal compatibility simplifies your field kit and eliminates the need to carry different battery types for different XP gear. If you own both an MI-4 and WS4 headphones, one spare battery covers both devices.

Battery runtime varies by accessory model and usage intensity. The MI-4 and MI-6 pinpointers, WS4 and WS5 wireless headphones, and XP remote controls all draw power differently depending on their features and how actively you use them. Runtime depends on factors like signal strength, volume levels, and continuous versus intermittent operation. Carrying a spare ensures you don't lose detecting time when your primary battery depletes during a productive hunt, regardless of which XP accessory you're powering.

This is a genuine XP replacement battery manufactured to XP's factory specifications. Third-party batteries often deliver inconsistent voltage or fail prematurely, which can degrade the performance of XP's sensitive electronics. Genuine XP batteries ensure proper fit, reliable power delivery, and compatibility with XP's charging systems. We stock only authentic XP parts because our team has seen the reliability issues that come with off-brand alternatives in the field.

This battery is designed specifically for XP pinpointers, headphones, and remote controls, not for XP metal detectors. The WS4, WS5, MI-4, and MI-6 accessories use this battery type, but XP's detector control units use different battery models. If you need a replacement battery for your Deus or ORX detector, check the specific battery part number for that detector model. This battery will not fit or power XP detector control units.

Your XP pinpointer or headphones will show reduced performance as the battery depletes. If your accessory no longer holds a charge after a full charging cycle, the battery has reached the end of its lifespan and needs replacement. Batteries degrade over time and eventually lose capacity even with proper care. Smart detectorists keep a spare charged battery in their kit so a dying battery doesn't force them to stop detecting. You can find more accessory options in our metal detector parts and accessories collection.

You should charge the battery fully before first use to ensure optimal performance. New batteries may have some initial charge, but a full charge before your first hunt ensures you get maximum runtime and proper battery conditioning. Use the charger designed for your XP accessory to charge the battery correctly. A full initial charge helps you start detecting with confidence that your gear will perform reliably throughout your session.

Leaving the battery installed in your MI-4 or MI-6 pinpointer during storage is fine for short periods, but long-term storage with the battery installed can lead to slow discharge and potential battery degradation. If you're storing your pinpointer for weeks or months, remove the battery and store it separately in a cool, dry place. For daily or weekly use, leaving the battery installed between hunts is acceptable and convenient for quick deployment in the field.

This battery operates at 3.7V with 630mAh capacity, engineered to match XP's power requirements for the WS4, WS5, MI-4, and MI-6 accessories. The voltage and capacity specifications ensure proper operation and reliable performance across all compatible XP equipment. Using a battery with incorrect specifications can damage your XP equipment or cause unreliable performance. Genuine XP batteries deliver the correct power profile for safe, consistent operation across all compatible XP accessories.

Most detectorists carry one spare battery for their pinpointer and one for their headphones if they run wireless models. If you're hunting in remote locations or planning all-day sessions, carrying two spares for your most-used accessory provides extra insurance against downtime. Battery needs vary by accessory model and usage patterns, so consider how heavily you use each piece of gear. Our team typically carries one spare for the pinpointer and one for the headphones on half-day hunts, and we double that for full-day trips. Check out our XP metal detectors collection for compatible detectors.

This battery is compatible with the MI-4 and MI-6 pinpointers specifically. If you own a different XP pinpointer model, verify the battery part number before ordering to ensure compatibility. The connector type and voltage must match your pinpointer's specifications. Contact XP or check your pinpointer's manual if you're unsure which battery your model requires. This ensures you get the correct replacement that will fit and power your specific equipment safely.

Use the charger designed for your specific XP accessory to ensure safe and proper charging. XP pinpointers and headphones have dedicated charging systems that work with this battery type. Always use the XP-supplied charger for your WS4, WS5, MI-4, or MI-6 accessory to maintain optimal battery performance and longevity. Proper charging practices help maximize your battery's lifespan and ensure reliable power delivery during your hunts. For more XP accessories and parts, visit our pinpointer comparison guide.
