How many volts does an 18650 battery have?

Introduction How many volts does an 18650 battery have? The rated voltage of a single cell is generally: 3.6 V or 3.7 V. The charging voltage is generally: 4.20 V (lithium cobalt oxide is 4.2 V-4.

How many volts does an 18650 battery have?

The nominal voltage of a single cell is generally: 3.6 V or 3.7 V.

The charging voltage is generally: 4.20 V (the oxide of lithium-cobalt is 4.2V to 4.3V).

The minimum end-of-discharge voltage is generally: 2.75 V. A voltage lower than this voltage can easily lead to a significant reduction in battery capacity or even its disposal.

Maximum charging termination voltage: 4.20 V.

Diameter: 18 ± 0.2 mm.

Height: 65 ± 2.0 mm.

Capacity: Above 1000 mAh, normal capacity is 2200 mAh to 3200 mAh. LG has the highest 18650 battery capacity, which can reach 3600mAh, but the price is not low.

Detailed information

The 18650 lithium battery has high safety performance, does not explode or burn; non-toxic, non-polluting, certified by RoHS mark; safety Performance is constant and the number of cyclesis more than 500 times; the high temperature resistance is good, and the discharge efficiency reaches 100% under 65 degrees. To prevent battery short circuit, the positive and negative electrodes of the 18650 lithium battery are separated.

The possibility of a short circuit has therefore been reduced to the extreme. A protection board can be installed to prevent the battery from overcharging and overdischarging, which can also extend battery life. The voltage of 18650 lithium battery is 3.6V, 3.8V and 4.2V, which is much higher than the 1.2V voltage of nickel-cadmium and nickel-metal hydride batteries.

The capacity of the Sanyo 18650 battery is not directly indicated on the battery core, but can be distinguished by the color of the positive cap (The battery will produce gas when discharged. The pole positive of. The battery has a protective cover When the.battery when the gas is released in a certain amount, that is, when the rated life is about to be reached, the gas will push the cover to open, causing the battery to decircuit) .
