    123 Battery Shoot Out

    You should have it now. Not huge.

    Harbor Freight NiCd Batteries

    Having been burned (literally) by cheap chinese cells, I would avoid them like the plague.

    New CBA-II Battery Final Version 2 Out With Discount until Feb 15th

    Re: New CBA-II Battery Tester Beta Software Thanks for the heads-up, I just installed it here. Looks good, but still no cell type appropriate for 123A cells.

    How can I email them direct to you?

    123 Battery Shoot Out

    If anyone is interested, I can zip up the results and email the raw data. You can download the CBA-II software from WMR for free and look at the data.

    123 Battery Shoot Out

    PS: Talking to the Mountain West guy, there is a firmware version in beta that does zero current (external load) and constant power discharge. Our load will be more or less a constant power load. Twelve switching power supplies, and a sustained load of over 10W from three cells, down to a few...

    123 Battery Shoot Out

    Nice! Much better artwork, and the name is a little less "schlocky" :) Frankly, I did NOT expect the PowPower cells to perform so well. I will be recommending that for one type of use, we use one of the big three, and for the other type of use, we use the PowPower cells. Shoot me a direct...

    123 Battery Shoot Out

    I just finished my own little shootout, using the west mountain CBA-II. I tested Duracell, Energizer, Maxell, Panasonic, Powerizer, PowPower Titanium, Sanyo, and Tenergy. I tested at 0.7A, 1.5A, and 2.2A which are ranges that make sense for my project. I set the cutoff at 1.6V, again this...

    123 Battery Shoot Out

    Ok, thanks! I thought you might have found some secret option menu or something I agree on the CP discharge, and it would seem like it would be easy to do. The time scale in amp-hours is a little silly since it's a constant current.

    123 Battery Shoot Out

    I'm curious how you got the watt-hour numbers on your testing. I just got a CBA-II, and I can only see it in amp-hours. It's a nice tester for general use, but my specific problem needs constant power loads, graphing in time, and a summary report showing watt-hours delivered.

    CR123A cell comparison

    I'm looking for a straight comparison of runtime between CR123A cells in a constant power system. My actual system will be roughly 5W from three cells in series, but I can probably use anything in a similar range of power. Constant current, or fixed resistance discharge curves don't help me...
