"Good battery"



This high energy density and capacity lithium-ion battery from Tenergy is perfect for flashlights, 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 18650s 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.

"Good battery"
"I decided to get a couple of these Tenergy's as they were on sale. Good performance & solid construction. 1 star knock as these are a little bit wider & longer than my other18650's. ie. Olight, Panasonic, Nitecore, Eastshine. Double check their measurements to make sure they'll fit your device. They fit mine, but just were tight."
"I live on a farm and have 4 small tactical style flashlights that I use regularly. . Saves me 12 or more triple a batteries a month and better for the environment. Hope these last a long time. Good price too. Thanks"
"Battery was used in a small fan. Has less power than original 2000MA battery and completely failed (Battery voltage 0) after 3 uses over 3 weeks."
"Very fast delivery."
"The batteries are high quality, i have ordered the same before and they have lasted years . Like they are advertised."
"Not sure if it's the charger's fault or the batteries fault but the charger seems to be maxed out when this battery is installed for charging. And by maxed out I mean that the charger has the ability to take shorter batteries but this battery appears to be the longest that it accepts and it does not do so very easily. Currently the issue is with customer service complaints at tenergy."
"Charges quickly and has a long life"
"Bought these batteries for a new flashlight! I could not be happier with the batteries so far. Flashlight is brighter with the use of these batteries. I hope they last as long as the charge does!"
"2600 mah is mid road capacity. . . . lasts a long time,,,higher mah means slightly longer runtimes. . . awesome price. . . . choose your MAH based on your usage"
