Car batteries imperceptibly support the operation of modern vehicles. Batteries have something to do with starting the engine, but also with the operation of electronic systems, they are indispensable parts of vehicles.
WHAT TYPES OF BATTERIES ARE THERE?
The most commonly used car batteries are lead-acid batteries, which can be divided into two main types, maintenance-free (SFL) and maintenance-free (MF) batteries. The electrolyte in SFL batteries should be checked from time to time and replaced if necessary. Although they can be purchased cheaper, they have a shorter lifespan and require more maintenance. Maintenance-free (MF) batteries operate in a closed system, so they do not require an electrolyte check or replacement. MF batteries are more expensive but last longer. In recent years, lithium-ion batteries have also become increasingly popular, especially for hybrid and electric vehicles.
WHAT IS THE MAIN FUNCTION OF CAR BATTERIES?
The primary purpose of the battery is to provide electricity to start the engine. In addition, the vehicle's electronic systems such as the radio, GPS, climate control, headlights and windshield washer system also use the energy provided by the battery.
A good car battery has a long service life and provides reliable performance even in extreme weather conditions. Ideally, the battery should be able to meet the specific energy needs of the vehicle, as well as to charge and discharge quickly, so that the vehicle's electrical systems work optimally. Battery capacity is measured in ampere-hours (Ah) and this value indicates how much current the battery can supply during a certain period of time. A higher Ah value means a higher energy storage capacity. The starting current (A) indicates the starting power, it is ideal if this value is also significant.
The technical data of the batteries includes the voltage (V), which is usually 12V for most passenger cars. In addition to the capacity (Ah) and starting current (A), manufacturers often indicate the lifetime of the battery, typically in hours or charging cycles.
