Frequently Asked Questions
Q1: What battery does the XTAR D26 dive light use?
The XTAR D26 series primarily uses 26650 batteries for maximum capacity and extended runtime. The newer D26 2800 uses 21700 batteries. XTAR offers high-capacity cells up to 26650 7000mAh and 21700 6000mAh.
Q2: Can I use third-party batteries with XTAR dive lights?
We strongly recommend using genuine XTAR batteries with built-in PCB protection circuits. Third-party cells may lack proper thermal protection, over-discharge safeguards, and consistent quality control — critical factors for underwater safety.
Q3: Do you offer bulk pricing for batteries and chargers?
Yes. We provide volume pricing for dive centers, equipment retailers, and distributors. Minimum order quantities apply. Contact our distribution team for a customized quote based on your volume and delivery schedule.
Q4: How long do XTAR 18650 batteries last?
XTAR 18650 4000mAh batteries are rated for 800+ charge cycles at 80% capacity retention. Actual lifespan depends on usage frequency, charging habits, and storage conditions. For dive operations, we recommend replacing batteries after noticeable capacity degradation.
Q5: Are XTAR batteries safe for underwater use?
XTAR batteries feature multi-layer protection: overcharge, over-discharge, short-circuit, and thermal protection. However, batteries themselves are not waterproof — only the sealed flashlight body provides underwater protection. Always ensure the flashlight O-rings are intact before submersion.
