Lead-acid batteries were first created as early as in the year 1850 by French inventor Gaston Plante. They’ve been in use in motor vehicles from then, as they are in tune with needs of car motors. They’re cost effective, and thanks to that they were able to dominate the market for a long time.
In cars they give electric impulse that is necessary to start motor, and for using lighting and other devices that consume electricity.
A big advantage of them is that their self-discharge rate is very low. It stays at the level of about 40 percent for a year. This is very good rate looking on all rechargeable batteries landscape. Actually is the lowest one. There are even solutions that discharge fully in just as little as three months. They’re also reliable and cheap.
