The quality and correctly selected characteristics of the car battery depend not only on the steady start of the engine, but also on the resource of certain units, therefore, it is necessary to approach the selection of the optimal car battery seriously.
The car battery has a number of parameters that need to be addressed to make the right choice.
1. Battery capacity. Capacity is the amount of power generated per unit of time. For example, a 60-hour battery with a current discharge of 60A will work one hour. A fully discharged battery is considered to be 10.8 V ac.
2. Battery (start) battery. The trigger value is the power of the battery, which it can emit for 30 seconds at an ambient temperature of -18 degrees Celsius. Accumulators with a large trigger indicator will be of use to those who operate the car in the cold region or if the car engine is old and has a thick oil (so that the engine will need a lot of energy).
3. Battery size. It is important that the battery is placed in a regular area under the hood, otherwise it will not be properly fixed. Might as well stop the hood.
4. Location of the terminals. The popularity of the battery is direct and reverse. What polarity is needed for a particular car is to be seen in the operating instructions.
Of course, the large capacity of the battery is good, but too much capacity can lead to overloading of the generator, and a regular undercharge of the battery that negatively affects its resource.
