Have enjoyed all the lurking and learning from everyone here on this forum... I will say my 'geeky' side has come out, and I now have a BC900, C9000 and a GT power A8, along with a bunch of Eneloops. I also picked up a few packs of the Tenergy LSD's, as I have used their 2300 mAh NiMh for a few years, and I thought I would see how they do.
My initial testing was done with the BC900 (as I didn't have the C9000 until just a few weeks ago), and I came up with the following:
After running thru the discharge/refresh function the Eneloops (AA) came to:
Batt 1 2 3 4
2110 2160 2130 2140
Discharge after 30 days:
Batt 1 2 3 4
1803 1845 1833 1829
.854 .854 .860 .854
The Tenergy (AA's) are as follows
Initial 1 2 3 4
2000 2010 2030 2060
Disch 1 2 3 4
1757 1772 1745 1793
.879 .882 .860 .870
Very encouraging from a 30 day standpoint, the downsides are the initial capacity and the sustained voltage, which for the Tenergy's was about .08 lower throughout the process than the Eneloops.
AAA tests below (at .25 Amp discharge) for 30 days:
Eneloop 1 2 3 4 ........ Tenergy 1 2 3 4
Initial 841 838 831 844........ 772 772 754 770
Disch 747 759 753 770........ 714 721 697 725
Ratio .888 .906 .912 .925 ....... .925 .934 .924 .942
Again, very encouraging, except for the initial capacity, and the discharge voltage was only about .05 lower than the Eneloops.
My apologies that I don't have any curves for you, as the Navy moved my transfer date waaaaay up, and I had to leave my precious testing behind. (my wife thinks I'm playing mad scientist in my office, what with the glowing lights of the C9000 and the GT A8). All I have with me currently is the BC900 and the batteries in this initial test, as I was determined to at least finish my initial 30 day check.
I had started working on the differences between doing the IEC charging on the C9000 vs the A8, as well as determining a good ratio for comparing the BC900 results vs the C9000, as the BC900 does give me better numbers on capacity than the C9000, but it also does charge up past the 1.47 voltage limit, which I believe was limiting the full charge on the batteries, especially the Eneloop's. Annnnd, since I had done my initial capacity tests with the BC900, I wanted a way to compare at least close to Apples to Apples with the results that either machine spit out (at least on a discharge function).
Anywho, I have since found that with a good IEC conforming charge on the Tenergy's their capacity on the BC900 goes to around the 2100 range, while the Eneloops hit 2200 (for the AA's) while the AAA Tenergy's hit 830ish, and the Eneloop 860ish.
When I get to my new duty station, my mad scientist cap will go back on, and I'll be able to get back to my machinations.
Overall though, I am fairly pleased with these initial results (and the IEC conforming capacity), and if I can't find Eneloops, I would be very satisfied with the Tenergy LSD's, especiall the AAA's, as you can pick those up for very reasonable prices compared to the Eneloops (or even other brands that I have shopped for).
