12V battery charging voltage: 12.6V for 3 cells and 16.8V for 4 cells.

[Specific Introduction]:

1. Floating charge. Refers to charging while working online. This method is often used in standby power supply situations. It cannot be charged below 12 volts, and if it is too high, it will affect the operation of the circuit. So, during float charging operation, the voltage is 13.8 volts.

2. Cyclic charging. It refers to the complete charging of the battery to restore its capacity. When fully charged, the charger should be continuously turned on for measurement, generally around 14.5 volts, and the maximum should not exceed 14.9 volts. After disconnecting the charger for 24 hours, it is generally around 13 volts to 13.5 volts. About 12.8 to 12.9 volts after one week. The specific voltage values of different batteries may vary.

A typical lithium battery has a single cell voltage of 3.7V and a fully charged voltage of 4.2V. The nominal voltage after series connection is only 7.4V, 11.1V, 14.8V The corresponding full charge voltage (i.e. the no-load output voltage of the charger) is 8.4v, 12.6v, 16.8v It cannot be a 12V integer, just like every 2V in a lead-acid battery, when fully charged, it is 2.4V, corresponding to only nominal 6V, 12V, 24V The full charge voltage (also the output voltage of the charger) is 7.2V, 14.4V, 28.8V, respectively I don't know what kind of lithium battery you are

The open circuit voltage of lead-acid power batteries for electric vehicles is about 13.3V when fully charged, and the starting battery for automobiles is about 12.8V when fully charged.

The open circuit voltage varies depending on the type of lead-acid battery. The above voltage values are measured when fully charged and left to stand for about 12 hours.

12V lithium batteries are connected in series with 3 or 4 lithium batteries. A combined battery pack, whose capacity is determined by the capacity of a single cell or the capacity of batteries connected in parallel, is a safe and environmentally friendly new type of battery.

12V batteries: According to material classification, they can be divided into 12V lithium batteries, 12V lead-acid batteries, 12V nickel hydrogen nickel cadmium batteries, and 12V alkaline batteries. A 12 lithium battery is a combination of three 3.7V lithium batteries in series. The voltage of a single lithium battery after being fully charged is 4.2V, also known as 4V in general. The voltage of the series batteries is added together, which is 4V/battery * 3 batteries or 12V, which is what we call a 12V lithium battery.

12V lithium battery specifications:

Voltage: 12V

Battery capacity: There is no standard capacity, and it is determined based on the specific requirements of the appliances or equipment. Generally, the capacity is 2200ma/h, 5AH, 10Ah, etc. Some electric vehicles can have a capacity of 20AH or 50AH. The more batteries are connected in parallel, the larger the capacity. According to the physics formula, in a parallel circuit: Itotal=I1+I2+I3 [1]

Volume: The volume of a 12V lithium battery should be determined based on its capacity, and there is no unified specification. The larger the battery capacity, the larger the volume

Weight: Nowadays, many devices require lithium batteries with larger capacity and lighter weight, such as electric vehicles. Previously, lead-acid batteries were used, but now many electric vehicles have become lithium batteries due to their large capacity, light weight, and small size.

Charging and discharging current: The charging and discharging current of a lithium battery is determined based on the power of the device, and the electric power formula is P=UI [1]. On the basis of a constant voltage, the greater the power of the device, the greater the required output current.

12V lithium battery applications: electric vehicles, power tools, laptops, mobile DVDs, UPS, GPS, medical equipment, etc

A 12V battery is a 2VX6 grid lead-acid battery!

The single cell full charge voltage of this type of battery can reach 2.2V-2,4V! The total no-load voltage can reach 13.2V-14.4V when fully charged at 12V!

That means the charging voltage should be 14-16V!

It also depends on the actual situation! If the capacity of the battery is much lower than the power of the charger! The charging voltage can be lower! On the contrary, it will be higher!

Overall, one condition must be met! That is, the charging current should not exceed 1/10 of the battery ampere hour! Don't lower than 1/5!
