What is the charging voltage of a 12-volt lithium battery?

18500 battery is a cylindrical lithium battery which has been widely applied in the battery, and can be applied to electronic cigarettes, toys, security, car electronics, etc.

Batteries, mature technology companies have Tiansheng, Po China manufacturers, such as, stable performance. The definition of the model law for: such as the type 18650, namely the battery to 18 mm in diameter, length of 65 mm, 18500 battery diameter is the length of 18 mm to 50 mm, cylindrical shape of the battery.

Voltage: 3.6 V (conventional batteries, commonality of the largest electronic products used for small power electric equipment 1 c discharge. According to the situation change discharge condition)

3.2V（Power battery can customize according to the situation)

Charging parameters: 4.2 V

Minimum discharge termination voltage is commonly: maximum charging termination voltage of 2.75 V, 2.75 V (Sanyo, Samsung, Panasonic, the newest large capacity of Tiansheng TS / 18500 charging termination voltage of 4.35 V)

Capacity: 3.6 V cobalt acid lithium technology now 1900 amh (according to Tiansheng Weiye technology)

Diameter: 18 + / - 0.2

Minimum discharge termination voltage is commonly: 2.75 V

The type 18650 lithium batteries

Maximum charging termination voltage: 4.20 V (Sanyo, Samsung, Panasonic, the latest large capacity 18650 charging termination voltage of 4.35 V)

Height: 50 + / - 0.3

Combination: s2p ICR18500-4

Standard continuous discharge current: 0.2 C

Maximum continuous discharge current: 1 c

Working temperature: charging: 0 ~ 45 ℃

Discharge: - 20 ~ 60 ℃

Product size: MAX35 * 54 * 83 mm

Finished product resistance: 250 m or less Ω

Lead models: the marking UL1007 / # 18, line is 150 mm long

Protection parameters:

The overcharge protection voltage/each string of 4.25 + / - 0.025 V

Discharge voltage protection 2.5 + / - 0.08 V

Flow value: 4 ~ 8 a

Generally 3.7 v lithium battery needs had a charge and discharge protection plate, such as no protective plate, only the battery is about 4.2 v charging pressure, because lithium battery voltage is 4.2 v, full charge of the ideal may damage the battery voltage is greater than 4.2 v, with this charging method at the same time need to watch the status of the battery.

Have protection board can use 5 v (4.8 to 5.2), computer USB5v or cell phone 5 v battery charger.

3.7 V battery charged by voltage, 4.2 V, discharge cut-off voltage of 3.0 V. So, when the battery open circuit voltage is lower than 3.6 V, it should be able to charge. Had better use 4.2 V constant voltage charging mode, can need not pay attention to the charging time. 5 v charge to overcharge danger.

12 V battery voltage: 3 section 12.6 V, 4 series of 16.8 V.

in detail:

1, floating. Refer to the online work while charging. This approach often used in standby power occasion. Not less than 12 FuChong electricity, high too much affect the circuit work. So, floating, voltage of 13.8 v.

2, charging circuit. Refers to restore the full charge capacity of battery, full of, constantly open charger measurement, generally at about 14.5 v, the highest no more than 14.9 volts. Disconnect the charger after 24 hours, usually at about 13 v to 13.5 v. About a week after the 12.8 to 12.9 v. The difference between different cell specific voltage value.

Lithium-ion battery monomer is usually 3.7 v, and the voltage is 4.2 v. Nominal voltage is 7.4 v 11.1 v, 14.8 v... after connecting in series. Corresponding with the voltage (i.e., charger no-load output voltage) is 8.4 v, 12.6 v, 16.8 v...It can't be a 12 v integer. Like every lead acid battery is 2 v, it is 2.4 v after fully charge. The corresponding voltage is only nominal 6 v, 12 v, 24 v...after fully charge(same charger output voltage) respectively is 7.2 v, 14.4 v, 28.8 v...I don't know what kind of lithium battery you want.
