Sea Dragon Mini 600 Technical Updates

1. Using CR123 versus 18650 battery

The Mini 600 light includes two CR123 disposable batteries that last about 60 minutes run time (burn time) at full power. For longer run time, we recommend using a Tenergy 18650 lithium rechargeable battery, which lasts 100 minutes at full power.

The light automatically detects the voltage difference between CR123 and 18650 batteries, so the 600 lumen output is about the same for both battery types. The only performance difference between the two battery types is the run time.

Warning: Do not use rechargeable CR123 batteries. The varying voltage and amperage will damage the batteries and/or light and possibly cause battery to catch fire or explode.


2. Using other brands of 18650 rechargeable battery

We recommend using the Tenergy 18650 Li-ion battery (3.7V, 2600 mAh) based on our extensive testing. There are many brands of 18650 lithium batteries available in the market, but we’re not sure what effect it has on the lumen output, run time or other performance factors.

If you do use another brand 18650 battery, make sure it’s from a reliable brand and has a “protected circuit”. Watch out for brands claiming high mAh rating, as that specification may not be accurate. mAh rating between 2600 mAh and 3000 mAh is sufficient.

Never use a damaged 18650 battery! Also replace the battery if the external sleeve/wrapper is cut, torn damaged in any way. The external sleeve helps to prevent short circuiting the battery. Short circuiting occurs if a metal objects makes contact with the + and – end of the battery at the same time, which will result in the battery overheating and may result in fire or explosion.
