Tenergy 18650

3.7V 2600mAh Li-ion Battery

This high energy density and capacity lithium-ion battery from Tenergy is perfect for flashlights, electronic cigarettes, portable power devices or other devices requiring 3.7 volts. The 3.7 Volt 2600 mAh capacity provides a long lasting, efficient discharge for maximum runtime for your flashlight or other device. The lightweight 18650 cell has been tested by the IEC (International Electrotechnical Commission) standard to ensure capacity, quality, and life span, so there are no surprises. Also, this 18650 has been manufactured under the ISO9001-2000 standard to assure top notch quality. These 18650 supply three times the voltage of 1.2V AA NiMH or NiCd rechargeable batteries. The unique patented PCB design prevents voltages outside of 2.5-4.25 volts

Note: These fully protected cells simplify usage with their integrated PCB. Perfect for your single cell application these cells are not for pack building as doing so will defeat the PCB protection which is matched to the correct voltage on a single cell. If you are building a pack please choose one of our other cells and the appropriate PCB.

Too big
These batteries are larger tan standard 18650's both in length and diameter. The large size of these batteries does not allow them to fit into flashlights or anything else that takes 18650's. Completely useless and a total waste of my money.
ConsToo big, makes them useless

good battery
It's a good cell. The one I got had a different label was not a flat top cell it was a button top, at least the one I got was.
Prosit's protected with a pcb bottom plate

not the best
These batteries are a little bit longer and bigger around, won't fit my mod so beware.
ConsNot the same size as Panasonic or standard 18950 batteries

Solid cell; good value
For the price, the Tenergy cells are a good value. Just be aware that despite the name - 18650 - these are a bit wider and taller, and in some lights it's enough to matter. This *is* mentioned in the description, but if you're old school like me and remember when they really were 18x65mm, this might come as a surprise if you haven't read the fine print.

Great Price and Power
Power was there with 2600mAh this flat top protected pcb lithium ion and great for the price. People on tight budget take notice.
Prospower and for the money can not be beat.

Incompatible flat top terminal
These have an unusual flat-top terminal - they do not work at all in a Nitecore TM11 (Tiny Monster).

Not Worth It
I bought some of these batteries and some others from same company (they were even more inferior). Totally not worth it for my needs. I thought flashlights I bought were messed up but finally purchased same sized batteries made by another company (I think it was samsung or sanyo: google reviews to find the best): and the flashlights worked for more than the 3 minutes that these batteries gave.

1 Question & 1 Answer
from Greensboro, NC asked:
May 28, 2014
Can this battery be recharged with my NiCad battery charger?
1 Answer
Unless your charger is compatible with Li-Ion batteries, I would not recommend charging these batteries with a NiCad charger. We carry Li-Ion chargers that will do the trick such as, the new Nitecore D2 Digicharger, Nitecore D4 Charger, or the Olight OmniDok Charger.
