    Duracel Procell D cell.

    An alkaline D cell should have had no problems with the current drawn in this case. 3W dropin for a 6D maglite would have only been drawing 350-400ma at most from the cells. An ANSI standard test for alkaline D cells is 600mA continuous for 2 hours per day. Cells don't vent during this test, nor...

    cursed alkalines!

    If the use by date was 2011, it's probably been in your phone since 2004. Until recently, Rayovac, Duracell, and Energizer all had 7 year shelf life guarantees. All 3 have now switched to 10 year.

    Varta LSD Date Codes

    What is the code on the cells?

    Dangerous explosion with 2 CR123A primary

    The opposite of charged is discharged, not "reverse charged." While I understand what you mean, it would be better to use the term "driven into reversal," which is what the battery industry uses when referring a cell that has been discharged down to zero volts and then beyond, into full reversal.

    Dangerous explosion with 2 CR123A primary

    You are correct; one cell doesn't "charge into" another depleted cell. This is an often repeated, but thoroughly incorrect, statement. When 2 cells are in series, the weaker cell will discharge sooner and the stronger cell can continue to drive the weak cell in to deeper discharge. If the weak...

    Rayovac Indestructible 3C vs Sportsman Extreme 3C

    The ANSI ratings on your Ledlenser P7 are 175 lumens for 1 hour, with a throw distance of 210 meters. The ANSI ratings for the Indestructible 4C spotlight are 150 lumens for 20 hours, with a throw distance of 350 meters. Your eyes deceived you. That's the nice part of having an ANSI standard...

    Rayovac Sportsman Extreme 300 Lumen Lantern - MORE INFO ???

    There's a 25% loss in High mode with the top on (180/240). There's a 25% loss in Low mode with the top on (75/100). The 300 and 120 lumen values you quote are from the previous packaging materials which were not ANSI ratings. 240 and 100 lumens are ANSI rated, and therefore lower. Putting the...

    Rayovac Sportsman Extreme 300 Lumen Lantern - MORE INFO ???

    On high, ANSI lumens are 180 with the top on and 240 with the top off. On "low", ANSI lumens are 75 and 100.

    FIRST 4sevens single-bay charge!! UH-OH!!

    A new unused alkaline cell might typically read anywhere from 1.55V to 1.65V, depending on the particular active materials it contains.

    What is the dirt cheapest cr123s around that can be trusted?

    BatteryStation branded cells are Rayovac cells, made in the USA. A good choice.

    Xeno 3.6v Batteries

    Safe? Maybe. Worthwhile? Not really. Those cells are rated for 230mA continuous current only. See the data sheet for them here: http://www.xenousa.com/pdf/XL-200F.pdf At a discharge rate of 200mA, the cells are rated for only 3.7Ah, which is really poor.

    Kelty LumaCamp Lantern: D x 4, 170 Lumens for 17 Hours, Cree LED x 2

    Only the three ribs are aluminum, the rest of the body is ABS plastic. It does appear to have infinitely variable output ("the advanced rheostat switch enables you to dim the light to your desired level"), however, which would be an improvement over the Remington.

    Kelty LumaCamp Lantern: D x 4, 170 Lumens for 17 Hours, Cree LED x 2

    Looks like this one http://www.remingtonlights.com/rm4dln.html but with a battery monitor built in, and with ANSI output ratings rather than the overly optimistic ratings on the Remington.

    Dangerous explosion with 2 CR123A primary

    Not really, unless people are taking zinc-air cells to the FD. No other type of consumer cell sold in the US contains mercury other than zinc air cells, which are what hearing aids typically use. Sorry for the off topic, but this kind of misinformation needs to stop spreading.
