This one is fake capacity battery.  Bought 2 of these ultrafire when I was still newbie in lithium batteries, actual capacity I think is about 1200mah.
Technically 18650 that has more than 3400mAh is not available for now.

Battery last longer or not depends on the load it is supplying energy for. High drain battery is just a battery that can supply high current that is required by load. Low drain battery cannot enough power to device that require high power.

So, basically the device you bought will come with required battery power capability. However, the high current battery can also be used on devices that require low current. It will not make battery drain power faster. In fact given high drain and low drain battery with same capacity, the high drain battery perform better since normally high drain battery can maintain rated voltage constantly much longer until very end compare to low drain battery.

This is a fake battery. Any ultrafire battery no matter what capacity is a fake battery.

It is well known in the market for fake battery.

Take the panasonic 3400mah as a bench mark for the max 18650 capacity. There is no 18650 battery higher than this 3400mah. So use this max capacity as limit when buy a battery.

Another way is weight the battery. 3400mah is heavier. Try weight this 6800 and compare.

I will throw away this battery. Useless. 

I was talking about high drain battery, not high capacity battery. Two different thing.

High Drain Battery and Low Drain Battery with same capacity will last the same time logically but practically maybe not. The low drain battery will drop voltage earlier than high drain battery thus will stop operating device it is powering earlier.

With that double price, better get the normal wan if don't require. Save the cost.

That's how the gadget manufacturing lower down the cost when built.

That's the main reason for purchase discouragement 

Anyway, if device is not requiring high drain I also think that there is no need to waste money on that, even though with suitable charger, it can be charge faster than normal battery.

For low drain high capacity lithium ion batt, I usually use Panasonic NCR18650B 3400mAh.
The light green color one.
Source : Lazada or taobao.

Btw, you want those with build in protection or raw flathead batt?

As Yushin said, Panasonic is the best. Beside that, Samsung, keepower and LG is goos also.

I don't no any geniue seller in lzd. I try 1 for LG and it is fake. Throw it away and leave a bad feedback on them.

If you want to get 1 or 2pcs, go over to Gadgetworld2u.com.

They are selling genuie battery.

Some torchlight will keep draining your battery till 0 and damage your battery. To protect the battery from over discharge we use battery with protection. Usually this is the pointy head type. Battery with protection usually about 2mm taller than unprotected version.

Some circuits board already have build in battery protection so they can use unprotected batteries.

So to use which type of battery, it depends lor.

Watch some video on youtube regarding 18650 battery type, very fast to learn up. I learn from watching youtube too. 

So it is true the brand name is ultarFIRE.

The Allefix has variable speed and quick release 

However, I don't know if it is compatible with any blade from known brand 

The variable speed at that price is impressive. That's all. Mine already old model Bosch GOP CE250 if not mistaken. Just single speed and cost like around RM500 last time. Not many in market that time I think even China one.

Honestly, I don't know when you need to slow it down    Being oscillating fast back and forth, it makes the tool more stationary and steady.

I think the quick release is good, less hassle changing blade like mine. The quick release lever/button position is at location where you don't hold your hand during operation. I believe it is safe to use.

The blades for different brand are different and even Bosch has new series that will nor work on old model like mine  . So, need to read carefully and also confirm with seller for compatibility since seller just copy paste ads that might not be accurate. The cheap China blade sometime colored black like carbon steel but actually just painted black    Anyway, the Bosch blade that I used also did not last that long 

I tried to find info on Allfix blade but not where to mention which brand is compatible with it. That is my main concern. 

Go for Worx Oscilating tool: https://shopee.com.my/WORX-WU681-450W-Corde...SkaAn06EALw_wcB

No regret!

Finally able drill an hole on ceramic after I purchase the correct drill using GSB120LI... around 1 minute plus for an ceramic hole....to me is not bad for cordless drill.

So, you get to know what blade brand compatible to the unit?

I can tell you that the oscillating tool is something very convenient for difficult to reach place.  :thumbsup:

China blade black color like carbon steel but the paint peeled off once used    Anyway, they are cheap. Just keep replacing them. Ori locally can cost RM100 for a kit of 3 Bosch blades 

Anyway the original blade that comes with my Bosch unit also did not last that long also. I have to read carefully and also confirmed with seller for compatible blade. Most just copy paste picture and spec to website. However, many China blades are multi brands compatible. I still need to make sure my older Bosch model compatible since the new model has different blade mount 

Yeah, ocsillating tool is essential for home diy.
Just placed order for this: https://shopee.com.my/WORX-WU681-Universal-...9761.7146465652

wait first I think. see how first 

It should outlast the mr diy one at 83% off from that price

I've read comment from users in Internet about even Bosch one. The comment was about how the mechanical was designed inside that cause his unit broken. He had two units broken until he wnet to other brand I think.

Well, sometimes we just believe that branded one can serve us good 

The broken tool the customer talked about was not even a year of usage
