What is the lead acid content of the battery
Lead-acid batteries suffer from relatively short cycle lifespan (usually less than 500 deep cycles) and overall lifespan (due to the double sulfation in the discharged state), as well as long charging times. The lead–acid battery is a type of first invented in 1859 by French physicist. It is the first type of rechargeable battery ever created. Compared to modern rechargeable bat. The French scientist Nicolas Gautherot observed in 1801 that wires that had been used for electrolysis experiments would themselves provide a small amount of secondary current after the main battery had been discon.
