TrustFire Protected 18650 3.7V True 2400mAh Rechargeable Lithium Batteries (2-Pack)

Pros: These 18650 Batteries are protected.
Really good capacity.
Nice new design, gives it a classy look.

Cons: - These batteries are a little on the long side, about 68mm.
- These batteries are a tight fit in my charger (Ultrafire WF-139)
- A little expensive compared with other Trustfire 18650 batteries.

Other: If you looking for a pair of good 18650 batteries, don't look further, you found them here.
Good capacity (don't know the exact measurements because I don't have a charger which can measure this)

Pros: - Very good build quality
- True capacity! measured 2300/2400 mAh
- protection works well

Cons: - one of 6 batterys is a bit leaning, but that doesn't matter.
- do not fit in "Zebralight H60", other Flashlights are no problem

Other: pefect quality @ perfect price
I have 6 of them, and usem them like every day! All working as on the first day.
!!use a good charger for fun as long as possible !!

Pros: - Fantastic Build Quality - Excellent Capacity which allows me to get roughly 1.5 hours out of my Ultrafire R2 501B on high - They look great - Awesome Price

Cons: - They are definately a bit larger than expected at just under 69mm

Other: Well made high capacity battery at a fantastic price

Pros: -They are somewhat slimmer than my grey TF18650 2400mAh (1 grey cell doesn't fit in 2 of my flashlights, but these black/red cells have no problem at all)
-Genuine capacity of at least 2400mAh, hold their voltages extremely well at high loads.
I have a 5A MC-E installed in the RC-G4 torch with a 1400mA driver (7135 chips). From the runtime tests, the grey TF18650 2400mAh could only hold full output (1.4A current draw) for ~35' then the light went into direct drive mode. However, when I used this B/R 2400mAh cell, the same light ran at full output for ~102 mins before a sharp drop off.
-They look pretty good, with the red and black and flame and everything :P, wrapping doesn't seem too durable though.
-Protection circuit seems to work, my TK30 (runs on 2x B/R TF18650) shut off automatically during its runtime test.

Cons: None at this point

Other: I'll probably buy only these cells in the future for my 18650s needs, they have the best values and quality here on DX.

Pros: - Protection seems to work (won't light up SKU 10855 ) - TrustFire has invested in wrap design (hopefully flame figures won't forecast bad incoming) - Two charge cycles are behind and I'm happy with batteries performance.

Cons: - There is a weak insulation spot located at the side of the minus pole, just where the protection circuit conductor is bent. The conductor will easily come visible, because it barely exceeds the battery maximum diameter. For example, if the battery side rubs with flashlight battery tube, then it is good to wrap one layer of insulation tape around minus side (but don't cover the minus contact). Otherwise original insulation may wear out right in first use and bare conductor may cause dangerous short circuit (if the flashlight tube is conductive material).

Other: I recommend these batteries, but advice to wrap insulation tape layer to the minus side. If there is a risk that original insulation rubs somewhere.

Pros: - They seem to pack a real punch, at least according to my multimeter
- Since the only place in my vicinity sells these for about 20$ for one, this makes it a bargain.
- I've being using them for about 20 cycles and the performance is still as if they were new.
- They are nice and smooth and fit in my flashlights just fine.

Cons: - Being batteries, they are pretty expensive. Although they are a lot cheaper than I've seen.
- The design is ugly if you care about these things.

Other: Good quality at a good price. I've used them for a while and the performance hasn't deteriorated a bit. The capacity seems as promised too. If you are buying a flashlight here, order these along, you won't regret it.

Pros: Quality build 18650 battery. This one works as expected, and two of them fit my TrustFire SSC P7 light (SKU 12761) perfectly. They seem to live up to their advertising, in my opinion.

Cons: None that I can tell. However, I have not tested power ratings or verified the 2400mAh rating.

Other: Works as advertised. No problems in charging or use. I would recommend, and will purchase these as replacements for current 18650's in the future.

Pros: - Very good build quality - True capacity! measured 2300/2400 mAh - protection works well

Cons: None. The protection does mean it is a tight fit in some of the smaller flashlights that can use an 18650, but that's more of a reflection of the flashlight, not the battery.

Other: Very good quality for a pretty good price, if you want to buy a set of good rechargeable and not worry about quality, then these are the set to get.

Pros: It's true-rated at 2400mAh. Lasts a long time with my Ultrafire flashlights that uses these type of batteries. Quality build and protection circuit works. Fits the Soshine chargers.

Cons: Does NOT fit my Surefire 6Z combatlight that has an R2 drop-in module, unfortunately. probably due to the protection strip. I didn't force it anymore, as it might damage the batteries.

Other: Get it if you need these type of batteries!

Pros: These batteries are awsome for flshlights. High volt plus a long runtime enables you to power your flashlights for a really long time and receieve a big result for your money. Build qualit is good and the price is not so bad either considering that its rechargable.

Cons: I hear claims that protected cells are longer but i bought lights where people rated that the light will not work with protected cells yet, these batteries never caused a problem and they are almost the length of a non protected cells.

Other: definitely worth the price to this day i had charged them once and the batteries are still going strong.
