Any part of the car requires timely maintenance and monitoring. The role of the battery in the car is one of the most important - if it fails, not only the auxiliary source of electricity is lost, but also the opportunity to start the engine. Car owners should regularly monitor the level of electrolyte, its density, level of charge, recharge the battery when the need arises. A large role in the battery play contact terminals - depends on them conductivity. It is safe to say that they are exposed to the strongest pernicious effects of current, and therefore deteriorate more often than many other details.
The choice of terminals for the battery.

Battery Basics
A car battery accumulates energy so that it can be used to start the engine, work the headlights, windshield wipers, transfer current to the entire electronics of the car when the engine is not working. The majority of models use lead-acid batteries. To choose the right battery, the material does not have such a value as other characteristics. Batteries are also chosen according to the purpose of the application, the charging method, and possible additional functions play a rather important role. Naturally, when choosing a car, the battery does not attach special importance to it, because there are more important and interesting characteristics. With all the variety of manufacturers there are only a few criteria when choosing a battery.
There are two types of devices: batteries that need to be serviced and those that are not needed. The fact is that in the first case, the car owner has the opportunity to replace the defective parts during operation of the device, but in the second case, the battery is sealed - you do not need to regularly inspect it or fill in additional water. The decisive role is also played by the charging method. There are charged and dry charged batteries. The difference between them consists only in the fact that for dry-charged ones it is necessary to mix special components in complex proportions in order to get the liquid poured inside. So, if you do not want to bother with difficulties, choose batteries charged. There are special covers with a separation system. They protect the electrolyte from spilling, and water from excessive evaporation.
What are the terminals
The biggest problem in battery operation is the oxidation or destruction of the terminal. In this case, the terminals must be replaced. On the car market you can find devices made of lead, copper and brass.
Lead
Most car owners prefer lead terminal. This material has good conductivity, it is softer than other metals, which is very good for crimping, in addition, it is resistant to electrolyte, does not create a galvanic pair with it, and therefore does not corrode. In addition, lead is cheaper than others, but it has a low melting point, which can lead to unpleasant consequences, especially in hot weather.
Brass
There is also a brass terminal. It is much heavier, but also stronger than others. It is easily deformed by pliers, which plays in its favor, because in order to work effectively, it must fit very closely to the current terminal. Also quickly removed, has good electrical conductivity and a high melting point of up to 950 degrees.

Copper
Copper terminals for the battery at first glance - the best choice. The best possible electrical conductivity, does not oxidize so much, has a larger contact patch. Melts at temperatures above 1050 degrees.
Which terminals to choose
Given all the above information, to know which terminals for the battery is better will not be difficult. Much depends on the conditions in which the product will stay (which machine, type of battery, direct voltage passing through the terminals, or other), as well as the material from which it is made. Car owners agree that lead terminals are the most versatile - they are quite heavy, soft enough, do not react with acid, and are much cheaper than products made from other metals. At the same time lead has a low melting point, sufficient, but not the highest electrical conductivity.
The situation is different with copper and brass terminals. Their electrical conductivity is several times higher, they are also quite heavy and soft, but they are highly susceptible to corrosion and cost much more lead. Such guides will suit fans to "stuff" their car with various electronics or cars from places with severe frosts. Therefore, if the tuning machine is not the main thing, you can safely choose the lead terminals. Their service life is much longer, they are cheaper, and the owner can only regularly look after them and pull up when the contacts go off.
In any case, the above terminals are used by car owners. Everyone chooses what is most appropriate in this particular case. Approach the choice of parts for your car responsibly and wisely.
