    Cold weather AA NiMH performance

    Last update, the battery I discharged in the freezer had been sitting at room temperature since last night. I just discharged it to .9 volts so I could charge both up again, and it had a capacity of 241mah. 1390+241= 1631 mah compared to the one I discharged at room temp at 1637 mah. You have...

    Cold weather AA NiMH performance

    I have no idea. My eneloops have at most 10 or 11 cycles on them. Most of those were forming charge to begin with and cycling them at different discharge rates when I first got them.

    Cold weather AA NiMH performance

    It is finished discharging and my IR thermometer said the freezer temperature was 6.7 F, last time I checked it said 5F. The 24 hour frozen eneloop AA discharged while inside the freezer to 0.9 volts had 1390mah capacity. That is almost 85% of the one I discharged last night at room...

    Cold weather AA NiMH performance

    Thanks. It is just over 40 minutes into the discharge test inside the freezer. The voltage dropped to 1.07 within 40 seconds discharging at 1 amp according to my ICharger 106b+. Withing 5 minutes or so, the voltage stabilzed at 1.04 and it has been hanging on there so far.

    Cold weather AA NiMH performance

    So I just was looking at 4 eneloops on top of my dresser that have likely been sitting there 2+ months since last charged. I grabbed two and put one in the freezer, both measured 1.326 volts open circuit on my multimeter. Updates on capacity I will edit this post and you will find the results...

    Cold weather AA NiMH performance

    Sanyo claims good performance from eneloop aa's down to -20C, whatever good performance means. They have 1c discharge curves down to -10C on their web page here: http://www.eneloop.info/home/performance-details/low-temperature.html . I have tested AccuEvolution D cell lsd nimh inside my...

    hunting light recommendation for friend

    I'm 49 and have killed over 1,000 deer in my life. I don't care who you are or what you shoot, eventually you will have difficult blood trails at night. Although I have a couple of high cri led's and one warm led, I only got those this year and have never used them blood trailing. Any other...

    AA > D parallel adapters

    I have 6 AccuEvolution LSD D cell nimh I purchased from battery junction several months back. When I recieved them, I discharged each individually at 2 amps using my icharger 106b+ and each one was between 9100 and 9250 mah straight from the package. I charged all 6 in series at 1 amp and let...

    What driver for 3 led mag mod?

    I have a few high cri seoul p4's and want to mod my 3D mag lite with 3 of them and have multiple levels, at least low/high and preferably low/mid/high, and no strobe/signal or any other useless to me modes. I will be using 3 D nimh batteries since I have several already and don't want to get...

    Deadly Weapons

    The NOHD isn't by power level of the laser, it is by the amount of power recieved in a defined area at the distance it falls to a "safe" level. As and example, according to the manual on my new to me IZLID, when focused on low power(45mW), the NOHD is 257 meters for a 10 second exposure. When...

    hobby charger question

    I just recently purchased a Venom Pro Charger, and it is going back for a refund. The software with it is not compatable with windows vista, even though the manual says that it is. Tech support for Venom straight up said it was not compatable with vista and had no clue the manual said it is, go...

    Panasonic Battery Could Power House for 1 Week

    Actually, there are many uses for this. Your average home uses around 1000kw of power each month, but I imagine most everyone here uses way more power than that, that is just a national average used in the utiliity industry. Your friendly local power company, or not so friendly, has to keep...

    Not exactly flashlight related, but led and driver related

    I'm looking to modify an inexpensive game camera that uses IR led's for the flash. The led driver in the cam has a few issues, it does not like NiMh batteries and overdrives the leds badly causing white out of pictures inside of 20 feet, draws 1.5 amps from the batteries (4 c in series), and...

    Help/info with problematic led swap

    Next question. I broke the fine negative wire too short to solder it back onto the emitter and now have to get the driver out of the pill. Any suggestions on desoldering the drive from the pill so I can solder a new wire on without destroying the driver completely? Or perhaps use a dremel and...

    Help/info with problematic led swap

    Just got home from work and was checking it out again. I pulled the emitter off of the pill leaving it soldered to the wires from the driver, and looking with a magnifer, there was some slight cracking of the wire insulation on the negative side. I could not see it with my naked eye, damn old...

    Help/info with problematic led swap

    Batteries are 2 primaries, duracell 123's, maybe 3 or 4 minutes run time on them at most.

    Help/info with problematic led swap

    I know the modes are the driver, but there is no mode anymore, just extremely high. It is far far far brighter than the 1 amp draw when it was on the solarforce drop in. Being current regulated, the driver from lumens factory should not be drawing that much from the batteries. As far as the...
