Frequently Asked Questions
Which Bigblue dive lights use this charger?
This charger, SKU BATCHR18650X4, is built for the 18650 x4 battery pack used in the TL4500P, TL4800P, TL5200P, VTL5500P, VTL8000P, VTL8000P-MAX, VTL10000P, VL5800P, VL7500P, VL6500-TC, VL7200P-TC, VL8300P, VL9000P, VL9000P-TC, VL10000P, and VL11000P dive lights.
How do I know when the battery is fully charged?
The charger has a built-in LED indicator. It glows red while the battery pack is charging and switches to green once the pack is fully charged, giving a clear visual signal without needing a separate meter.
Should I leave the battery in the charger after it reaches full charge?
No. Bigblue recommends removing the battery from the cradle promptly once the LED indicator shows green and the pack is fully charged, rather than leaving it in the charger indefinitely.
Is this the 3-bay or 4-bay charger?
This is the 4-bay charger, SKU BATCHR18650X4, built for the 4-cell 18650 lithium-ion battery pack. It is a different unit from Bigblue's 3-bay charger, which is designed exclusively for the CB4000P light and is not interchangeable with the lights listed for this charger.
