4 FAQs about Battery cell 21700 nominal voltage

How many volts does a 21700 battery have?

2170s may have a voltage range between 2.5 volts and 4.2 volts, or a charging voltage of 4.2 volts, but the nominal voltage of a standard 21700 is 3.7 volts, just like the 18650s batteries. There are two types; protected and unprotected. We absolutely recommend protected 21700 batteries. Protected 21700 batteries generally have a button top.

What is the difference between a 21700 and a 2170 battery?

The 21700 is physically larger than an 18650 battery, and AA/AAA batteries. 2170s may have a voltage range between 2.5 volts and 4.2 volts, or a charging voltage of 4.2 volts, but the nominal voltage of a standard 21700 is 3.7 volts, just like the 18650s batteries. There are two types; protected and unprotected.

Are 21700 batteries based on lithium ion?

However, most 21700 cells are based on lithium-ion (Li-ion) technology, which is widely used across many types of rechargeable batteries due to its excellent energy density and long lifespan. There are several types of lithium-ion chemistries that could be used within the 21700 format:

What is a 21700 protected battery?

21700 protected batteries have an electronic circuit. The circuit is embedded in the cell packaging (battery casing) that protects the cell from “over charge”, heat or “over discharge”, over current and short circuit. A 21700 protected battery is safer than an 21700 unprotected battery (less likely to overheat, burst or start on fire).
