Battery test/review summary

Thanks for all!

Maybe you could "evaluate" or judge the cells with a final grade, e.g. 10/10 or five stars ;)

Very nice HKJ! Thanks so much for sharing your data with us here in such a clear format.

Frontpage'd and Sticky'd.

Looking at the first photo I was amazed looking at the batteries number

suddenly I realized that you still have half of work to do.. go back to your job slave xD

Joking we really appreciate your professional and dedication, you are the reference point in that, ty a lot for your time m8 :)

btw a dumbs proof star/score system like suggested from kreisler about capacity (at 1,3,5A), price/quality, PCB quality, safety

yes that is great and easy to read but I bet that not all will try to read the graphic

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.

Thank you for the test. I bookmark it on my browser to find it quick in the future.

Nicely done tests/review. I appreciate your effort!!

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.

Damn quoting just that make me look awful and hated by all xD

I was just joking, we know just charge/discharge at 0,2A 1 battery 1 time take more of day...

so pls just read "really ty for you job is really appreciated" from my post above :)

I enjoyed that remark, it was a fun way to show your appreciation for my work.

In future, i only buy Very Good cells.

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.

Keep up this excellent work, HKJ :D

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.

Thank you for all of your efforts HKJ .

thanks very much

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

Thanks!!

You sir, are a genious!!

Especially thanks for stating which bars are important for which lights/outputs, never would have figuered that one out for myself.

And thus we have learned another great thing

HKJ's reviews are always superb! Thank you!

all 3 of my wives approve of this....2 of them continue to beat me

Hi

what about the new Trustfire 3000mA we can see in the first picture? Maybe I just misunderstand your charts ... I can't find them. Thanks
