The long awaited xx123 battery tests for the Arc LS are now underway!!

1st Test: Arc LS with Surefire SF123A.

Battery has a "use by" date of April 2011.

Initial brightness: 71,100mcd / 5 seconds

Initial DC current: 430mA after 5 seconds

Initial PV current: 18.5mA after 5 seconds

Timed PV (photovoltaic cell) curve - measures relative light intensity...

10:00am 15.20mA

10:15am 14.63mA

10:30am 14.18mA

10:45am 13.96mA

11:00am 13.87mA

11:15am 13.78mA

11:30am 13.64mA

11:45am 13.54mA

12:00pm 13.38mA

12:15pm 13.05mA

12:30pm 12.55mA

12:45pm 11.85mA

1:00pm 10.25mA (battery is draining at a slightly faster rate now)

1:05pm 9.16mA

1:10pm 7.94mA

1:15pm 6.66mA (I hope you're wearing clean underpants...watch out for flying horses!)

1:20pm 5.98mA

1:25pm 5.31mA

1:30pm 4.84mA

1:35pm 4.49mA

1:40pm 4.21mA

1:45pm 3.89mA

1:50pm 3.47mA

1:55pm 3.17mA

2:00pm 2.92mA

2:05pm 2.46mA

2:10pm 2.24mA

2:15pm 1.46mA

2:20pm 0.963mA (A bit dimmer, but whiter, than a white Infinity)

2:25pm 0.522mA

2:30pm 0.328mA

2:35pm 0.254mA

2:40pm 0.211mA

Battery has an

*open circuit / high impedance*voltage of 0.92V after a 30 second resting period.

After approximately 1 minute, it was reinstalled and

**the Arc LS restarted!**

Threshold of usability reached; this test is over. Light can still be used to carefully navigate indoors, and can still find toilets, furniture, or pet's tails; but it isn't useful for much else at this point.

Testing will begin anew tomorrow morning with the Energizer e2 lithium.
