What is a 21700 battery?
A 21700 battery is a high capacity lithium ion rechargeable battery. Their proper name is a “21700 cell”. The 21700 cell has voltage of 3.7v and has between 3000 mAh and 5100 mAh (mili-amp-hours). The 21700 is physically larger than an 18650 battery, and AA/AAA batteries.
How much power does a 21700 mAh battery hold?
You don't really notice the size increase, but you definitely feel the performance upgrade. At its core, a single 21700 cell usually holds 4000–5000 mAh with a nominal voltage of 3.6–3.7 V. Fully charged, it hits 4.2 V, and cutoff usually happens around 3.0 V.
What is the difference between 21700 lithium ion and 21700 battery?
The dimensions of the two types vary greatly, with one being significantly longer than the other. This is because of their different capacities—the larger capacity of the 21700 lithium-ion allows it to be larger in size and have high power. 21700 batteries have a typical capacity of about 4000 – 5000 mAh.
How much energy does a 21700 battery have?
Energy density: The 21700 batteries have an energy density ranging from 250 Wh/kg to 300 Wh/kg. Size and weight: The battery's dimensions are 70 mm in length and 21 mm in diameter3. The weight typically ranges from 50 to 70 grams. Voltage: The voltage of a 21700 battery typically varies between 3.6V to 3.7V when it's in use.
