I was thinking about it when starting the battery test, but decided against it. It is simply to difficult, because it depends on the situation what parameters are important. What is best: A short flat top battery or a long battery with a small button top, both using the same cell?
I do give a little bit of rating with "good" and "very good" in the conclusion. For a "very good" battery it must use a cell from a big manufacturer and not have any issues.
That picture only show about half the batteries I hope to test and with one to two batteries each week it is going to be a long time before I am finished.
The testing is running 24/7 , except when I need my equipment for other stuff.
HKJ, I admire your dedication, professionalism and details given to all your tests. And thanks for sharing with us here! Whenever I needed guide, it is always your site. Cheers
PS: I still need some time to digest all those charts, I know, I'm slow.
I will add more ratings when I get to the cheaper cells. The Trustfire Flame 2400 I called "Acceptable for a cheap cell", I do not like batteries that are way below specified capacity.
When I get to batteries where the two tested batteries has very different capacity, I will have to find some lower rating, because this is a sign that the cells are old, used or very cheaply manufactured.
I is always possible to ask question about them, this might also help me to write a better explanation.
I've been feeling a little uneasy about choosing the 2250s over the couple of good 3100s for use in the DRY. I figured that over many cycles they might fare better than others, since they'll handle even higher current discharge than i will do - but now in your second and fifth graphs, I see another reason to choose them. WOW. I might order some more lol
edit; actually, I misunderstood the 5th graph at first. still, very interesting and helpful to visually compare this data. hard to imagine how confusing all the available offerings would be w/o this sort of work. thanks
