Learn how to choose, use, and maintain the XTAR 18650 battery for Sea Dragon Mini lights, including compatibility, capacity, and safety tips.
Quick Answer
The XTAR 4000 mAh 18650 battery is a reliable replacement for many Sea Dragon Mini dive lights, offering high capacity and built-in protection. Always confirm your light model's compatibility before purchasing.
Why capacity and protection matter
A dive light battery needs to deliver consistent power during your dive. Higher capacity means longer burn times, but it also means you should match the battery to your light's requirements to avoid over-discharge.
The XTAR 18650 features a built-in overcharge/discharge protection circuit, which helps prevent damage from common user errors like leaving the light on after a dive.
Compatibility considerations
The XTAR 18650 is designed for Sea Dragon Mini 600, 650, 900, 1000, 1200, 1300, and 1600 models, as well as other light brands that use 18650 cells. However, always verify the physical length and button-top vs flat-top design if you're using a non-SeaLife light.
If your light takes a different battery type, this battery won't work. Check your light's manual or the product listing for the exact battery requirement.
Frequently Asked Questions
- Will this battery fit my Sea Dragon Mini 1300?
- Yes, the XTAR 18650 is compatible with Sea Dragon Mini 1300 models, along with Mini 600, 650, 900, 1000, 1200, and 1600. Always confirm your specific model variant.
- How do I charge this battery?
- Use a dedicated 18650 lithium-ion charger. Do not charge it inside the dive light unless the light explicitly supports in-situ charging. Invest in a quality charger that matches the battery chemistry.
- When should I replace the battery?
- Replace it when you notice significantly reduced runtime, physical damage, or swelling. The built-in protection helps, but cells age over time. Check the battery before every dive trip for visible wear.
