How many volts is a typical battery for automobiles?

Different types of batteries for automobiles have different voltages:

1, nickel-cadmium batteries (Ni-Cd), voltage: 1.2V; service life: 500 times; discharge temperature: -20 degrees to 60 degrees; charging temperature: 0 degrees to 45 degrees.

2, nickel-metal hydride batteries (Ni-MH), voltage: 1.2V; service life: 1,000 times; discharge temperature: -10 degrees to 45 degrees; charging temperature: 10 degrees to 45 degrees.

3, lithium-ion battery (Li-lon), voltage: 3.6; life: 500 times; discharge temperature: -20 degrees to 60 degrees; charging temperature: 0 degrees to 45 degrees.

Correct use of automotive batteries:

1, the density of the electrolyte should be adjusted in accordance with the density of the different regions, different seasons in accordance with the standards to adjust accordingly.

2, in the loss of electrolyte should be supplemented with distilled water or special replenishment. Do not use drinking water instead of pure water. Because pure water contains a variety of trace elements, the battery will cause adverse effects.

3, in the start of the car, uninterrupted use of the starter will lead to battery damage due to excessive discharge. The correct way to use is to start the car each time the total length of time is not more than 5 seconds, start again at intervals of not less than 15 seconds. If the car does not start several times, you should look for the cause from other aspects such as electric circuit, ignition coil or oil circuit.

4, daily driving should always check the battery cover on the small hole is ventilated. If the battery cover hole is blocked, the hydrogen and oxygen generated by the exhaust, electrolyte expansion, the battery shell will be broken, affecting the battery life.
