How long do car batteries last? Car batteries are the main sources of supply of cars with the power, but at same time as conventional batteries, sooner or later they may be appear out of power. Modern car batteries can supply with energy from 2 to 3 years, which means that it is at such intervals; each motor technician is forced to look for options for replacing the "source of energy.”

Capacity of a typical battery life is 45-65 amp/h

The current starter is approximately 180 amps, that is, in theory, defective battery can drive the engine for about 15-20 minutes, in reality this does not happen and is not required serviceable engine starts in a few seconds, the remaining battery capacity is spent on something that would fuel consumers in the parking lot, to compensate for the 2-3-fold loss of capacity in the cold, to compensate for aging batteries, etc.

Defective battery can power a signalization (10 ma) about half a year, salon bulb (5 W, 0,5 A) approximately 100 hours. Marker lights about 25 hours. And just forgotten lights or powerful audio system really quickly put even defective battery.

Batteries do not live forever, usually 2-3 years.

During this time, the battery gradually loses capacity, it appears, usually at winter start or after a long parking cars. With daily summer operation loss in capacity is not visible.

If the battery is 'planted' to zero, then it loses its capacity several times forever, it cannot be restored, each successive planting of fast finishing off the battery.

Thus if your battery is not young, when he landed to zero, for example, after parking in a few days you could not start the engine, you forgot to turn off lights after work and were unable to be got, 'live up to the city' with a faulty generator, etc., Your Always let you down in the winter.

And that would not get up twice about the care and charge.

If the lid of the battery tube are visible or easily remove the lid, then about once every half a year it should be topped up with distilled water, the water topped up to the bottom of 'wells' under the hood. Water is bought in the automobile. Keep in mind that the lower bound on the cover may be a drop of caustic acid. Wear gloves; wash those places which were placed on the lid. No other care is not put a modern battery. Of course, the easiest way to buy a charger, but if you often outside of civilization, then put in the glove compartment diode, if possible from the available material, such as a desk lamp or electric gather for charging the battery from the socket.
