Batteries
In the majority of vehicles with an internal combustion engine, batteries serve as a source of direct current electrical energy. They power electrical components in the vehicle when the engine is off and provide the electrical energy necessary to start the engine.
Which battery to choose?
Although they all look similar, vehicle batteries differ significantly. By separating them by the battery construction type, we can distinguish:- Lead-acid batteries: the most commonly used type battery, filled with traditional electrolyte, i.e., a liquid solution of water and sulphur (sulfuric acid);
- Gel batteries: instead of traditional electrolyte, gel batteries are filled with acid mixed with silica in the form of gel. They are mainly used in scooters and motorcycles;
- EFB/AFB/ECM batteries: batteries with extended durability. They have a larger electrolyte tank, created for vehicles equipped with start-stop systems. They are not resistant to deep discharge;
- AGM batteries: much more efficient than the traditional lead-acid batteries, a more technologically advanced battery, with separators made of glass microfiber mat or polymer fibre. This is a relatively expensive battery and not as resistant to high temperatures, so they cannot be installed in the engine compartment.
