rings are already fitted to the uvBeast at the threads. These
seal the uvBeast from dust, moisture, and water.
Spare O-rings are inside the internal packaging.
PLEASE NOTE [OTHERWISE YOU MAY THINK
YOUR DEVICE IS DEFECTIVE]:
The Li-ion cells will be found already inside your uvBeast V3.
However, for transportation you’ll notice a thin white disc
covering the end of the cell (between the cell and the inside
tail cap) –sometimes it can get affixed to the inside tail
cap. Please discard this, as its only function is to prevent
parasitic drain and circuit connection during transit. (Also,
please note that the Li-ion cells will arrive semi-charged, but
may need further charging). So on first start it's always best to
fully charge the cells otherwise you may think the unit is
defective. For future reference, the positive ends of each cell
are inserted first into the barrel i.e. the positive ends face the
LED head while the negative end faces the tail cap).
Batteries and Accessories Included
PLEASE NOTE: For your future reference only button-top
18650 Li-ion should be used (not flat-top).
Some quick info on the cells. We’ll only really convey what’s
most important. Each of the cells is designated as “protected”.
This means that there is a PCB fitted to each battery which
prevents the cell from two events happening: (1) Over-
charging the cell, and (2) Over-discharging the cell. Both can
damage the cell and adversely affect long-term performance.
The li-ion cell can be charged between 300 to 500 times as
given by industry benchmarks, but this is also acknowledged
to be conservative and so you may even achieve up to 700 to
1000. These are known as “charge cycles” where one-cycle is
equivalent to fully charging the cell and then fully discharging
the cell. To further optimize the full working life of the 18650
cell it is better practice to charge the cell when it is about 80%
depleted rather than fully depleted, although full depletion
with a “protected” cell is however still acceptable.
