STABILITY ANALYSES OF THE
This is of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (1).

AND THE
Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (2).

(HIGH POWER MODE)



Blue 2400mAh cell.
Different software and different Arctic blue laser were used.
Maximum intensity was used here; the battery charge lasted for 44.05 minutes.
This is of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (2).
Readings taken every 1,000mS (1 second); my new LaserBee 2.5W USB Laser Power Meter w/Thermopile was used.




Blue 2400mAh cell.
Different software and different Arctic blue laser were used.
Maximum intensity was used here; the battery charge lasted for 30.10 minutes.
This is of the Wicked Lasers Spyder 3 Arctic 445nm 1W Blue Diode Laser (1).
Readings taken every 1,000mS (1 second); my new LaserBee 2.5W USB Laser Power Meter w/Thermopile was used.




Blue 2400mAh cell.
The green line represents the laser itself; the red line represents maximum output and the yellow line is average laser power throughout the entire measurement cycle (61¾ minutes).
Maximum intensity was used here; the battery charge lasted for 61¾ minutes.

Tan 2,200mAh cell.
Maximum intensity; sixty two minutes.
Readings taken every sixty seconds (1 minute).




Blue 2,400mAh cell.
Maximum intensity; forty seven minutes.
Readings taken every sixty seconds (1 minute).





This is using using a different 18650 cell (2,400mAh).
Maximum intensity; forty five minutes.
Readings taken every sixty seconds (1 minute).




This is using the 2,400mAh 18650 cell that I used in the analysis shown directly above.
Maximum intensity; 44 minutes.
Readings taken every sixty seconds (1 minute).





This is using using a different 18650 cell (2,200mAh).
Maximum intensity; eighty one minutes.
Readings taken every sixty seconds (1 minute).




This is using the orange 18650 cell (1,400mAh) furnished with the product.
Maximum intensity; forty six minutes.
Readings taken every sixty seconds (1 minute).




This is using the orange 18650 cell (1,400mAh) furnished with the product.
Maximum intensity; five minutes.
Readings taken every six seconds.





(LOW POWER MODE)







Another minimum intensity analysis using a different 18650 cell (2,200mAh); 354 minutes (5:54) until extinction.
Readings taken every five minutes.




Another minimum intensity analysis using the same 18650 cell as above; 255 minutes (4:15) until extinction.
Readings taken every five minutes.
I bumped something I shouldn't have and queered the test approx. 90 minutes in, so I charged the battery and re-ran it with identical parameters.
After 3:15 into the new test, I noticed that ambient light spoiled it, so I charged the battery again and ran it for a third time. Third time's a charm, right?






Another minimum intensity analysis using a different 18650 cell (2,400mAh); 265 minutes (4:25) until extinction.
Readings taken every five minutes.
Note that there is no partial recovery following the rather rapid drop-off right at the beginning; this time it falls and then achieves a stable threshold without additional fanfare.




This is using the orange 18650 cell (1,400mAh) furnished with the product.
Minimum intensity; 205 minutes (3:25) until extinction.
Readings taken every five minutes.





This is using the orange 18650 cell (1,400mAh) furnished with the product.
Same as above; 224 minutes (3:42) until extinction.
Readings taken every five minutes.
I'm honestly not certain why the battery life is so different -- environmental conditions were virtually identical, and the charger was displaying a green light (indicative of "charge cycle complete") both times.





This is using the orange 18650 cell (1,400mAh) furnished with the product.
Minimum intensity; 279 minutes (4:39) until extinction.
Readings taken every six seconds.
This also serves as a battery discharge analysis.





This is using the orange 18650 cell (1,400mAh) furnished with the product.
Minimum intensity; five minutes.
Readings taken every six seconds.

The new "
" icon was added to my website to denote this analysis having been performed on lasers. The Arctic just happened to be the first laser to undergo this test.





Update 06-22-11: New battery discharge analysis was made using my new LaserBee 2.5W USB Laser Power Meter w/Thermopile.

Update 06-28-11: Two additional battery discharge/stability analyses were performed on both of my Arctics using the LaserBee and the laser power output logging software on my Win 98 "lab" computer.

Nice long duration battery tests on the Arctic and
different batteries...

What Brand/Model/Supplier of batteries were the
ones that ran the longest according to your charts...?

Good morning Jerry,

Unfortunately, none of the batteries are marked as to their manufacturer, so I'm rather ill-equipped to furnish that information, sorry about that. :(

The blue cell that I ran the latest analysis of is marked:

KL 18650 2400mAh 3.7V

That's all -- no other markings are visible on it. :(
