I have an XXX-fire battery, "6000" Mah lol.

Hi people. I payed like 99 pence for this battery, as I thought the 6000MAH claim was quite funny. Thing is, I tried it in my torch, and it actually works well.

Any idea what MAH it really is? And would it be safe to use in my torch, or should I stick to the 25R’s.

a bit of searching around here would have told you.
highest REAL capacity being 3600 right now.
post a link to where you got it.
another fire name for the list of shame.

You might have lucked out and received a battery with around 2,400 mAh. I've run into that maybe once before. Thing is, though, it will probably soon begin to lose its capacity to charge up to where it charges up to now since it is still spent and probably right at ready to be thrown out.

No it’s not safe to use. Often the higher the fake mA it says on the label the worse it can be under the label. Capacity wise and safety wise. Just a gamble.

Cut the label off and tape it on a good cell. But don’t trust that cell.

It can be anything, you can see here where I disassemble some batteries:

Ok. I will just keep it and never use it, as I knew the highest currently available capacity, and found the 6000MAH claim funny lol.

I already know the highest from my other hobby, vaping. It was bought as a joke as it was 99 pennies and the 6000MAH claim made me laugh :).

I got two 26650 7800 red ultrafire batteries, ordered for a long time ago this week.
Actual mAh after charge - discharge - charge test on Opus BT-C3100 and LiitoKala Lii500 was 2200 and 2300 mAh.

I really need to get myself a better charger, one that tells me the capacity.

Can anyone recommend one that doesn’t break the bank? I am talking like under £30, my current charger, a nitecore i2 was about £13, but has no digital display, I wish I had gone on the next page on the shop I bought it from as they had the nitecore with the digital displays that tell you everything lol.

It would be interesting to see what this actually tests out as.

At this rate, they should have 10k to 20k mAh 18650’s by next year and maybe 100k mAh by 2017! Our flashlights will have a million lumens and be able to run in turbo mode for an entire week!

I have a Nitecore D4, but that can only be used for charging, so no point going for that.
Two choices, like I see it:
Opus BT-C3100: Link to Gearbest.com - if you live in one if the 11 countries they send to from their EU warehouse, you get it for $33, if not it cost $43.
LiitoKala Lii500: Link to AliExpress - the seller I have ordered two from…price $28 - free shipping, like Gearbest.com.

That “I tried it in my torch, and it actually works well.” is the reason these guys can keep going and get positive reviews on Amazon and Ebay etc. Just think back to when you hadn’t ever tried the new LED lights you just bought, remember how bright they were and how you were impressed?

People like you were then, pop that Crapfire battery in and think “WOW, this works great!” and leave a good review for others. Since you have no way to test it and if you had no batteries, nothing to test it against, you wouldn’t know the difference and think it ran such a bright light for a long time (until it started to degrade). And on average you probably wouldn’t use it very often or for very long and would never know how short its run time is. You would stop charging the battery up as much as you stop using it and a year later when its not working think “ah well, I haven’t used it in a while” and toss the battery and buy a new Crapfire. Most of the time it wont explode either, so you are a “happy Crapfire customer”. I think its kind of interesting how these can be so bad, yet get so many positive reviews and people are so clueless about them.

I was also clueless and started off buying Ultrafire batteries, thought it odd it didn’t run very long and researched, I bought some Panasonics and compared run times and was amazed, then I found here! I kept using them, but then my Ultrafires started to degrade as well and I thought it wasn’t worth the risk and the remaining poor capacity to even use them. My Panasonic Orbtronic batteries are still working while those Ultrafires (that had started out an estimated approximate sub 1800mAh) were probably already below 1000mAh after maybe 10-20 recharges when I tossed them two years ago.

I have 3 of the OPUS 3100. 2 of the 2.0’s and a 2.1. When it came out they called it the dream charger. The user interface is just a pleasure to use and it is literally 4 independent chargers in one case. All the functions can be mixed or matched so it could actually accommodate 4 different types of cells performing 4 different tasks, all at the same time.
I think it is the ultimate in function, flexibility and use.
Don’t forget it can handle NiMH and Li Ion. Even at the same time!

EDIT:
I just read B42’s post above and he is absolutely correct. It wasn’t until I got my 3100 that I really realized how bad those “crapfire” cells are. They are just garbage. Almost any cell I salvage from a used spent laptop pack are better.

On this link, it says between lots of lines, that min capacity is 2100mAh…, so at least one “honest” seller there.

Maybe not. I have seen lots of flashlights for sale with rated lumens and “actual” lumens, knowing that the so called honest actual number is a lie too.
OTH, the very first set of cells I bought 3 years ago were UltraFire 4000mAh. Like B42 says, they charged up and WORKED. So what was I to know. After I got my OPUS I checked them. I was surprised actually to find that they were about 2000mAh. Actually the best CrapFire cells I had. All others came in around 500 - 700 mAh.

I also have the OPUS and while I agree it seems to be a relatively good charger, its kind of noisy with the fan and smelly: for some reason the plastic they use is very stinky (I think its the plastic, but I really dont know why it stinks) and when the fan goes on it blows the smell around, so much so that I dont like walking into a room where the OPUS has been on for a while. So while the mAh reading is kind of nice, I end up not wanting to use my OPUS and haven’t used it for months.

I completely agree about the edit above, every laptop cell I’ve harvested from new cheap laptop battery packs is also doing very well after many recharges, and just as cheap to cheaper than “xxxfire”. I made sure to research and only get packs that others here have found high capacity Samsung and Panasonic cells inside. If you want to go cheap, learning how to harvest them safely from a laptop battery pack may be the way to go, but of course there is some danger harvesting them and you need to check and monitor voltages for a while to ensure the batteries are fine.

The pics of 6000 mah disassembly is awesome. The extent of some people go through to make a buck is amazing.
