Because the ban on lead-based paint, using lead was designated to the manufacturing of car batteries and others of the sort. In spite of being a very hazardous product, there's no refuting that lead-acid batteries continue to be the most preferred kind of chargeable battery today. The dependable APC UPS battery is one of the tools that substantially takes advantage of lead.

The lead-acid battery, invented by French physicist Gaston Plante in the mid-1800s, was the first of its kind. His design, still being used today, asked for a pair of pure lead rolls dipped in a tank full of sulfuric acid. As with a common car battery, the lead-acid battery has two electrodes; one plus and one minus. The modern lead-acid battery consists of a series of pure lead and lead dioxide plates in a sulfuric acid solution.


When the UPS battery is using up energy, both positive and negative plates eventually become lead (II) sulfate. The chemical reaction produces electricity and water, which is what became of the sulfuric acid in the process. Typical lead-acid batteries can only yield up to 40 watt-hours per kg of electricity as a result of the water's weight.


The electrical existing changes the composition of every little thing inside the lead battery once more. The positive plate, the pure lead that is currently lead (II) sulfate, is dissolved and mixes with the water, converting it back into pure lead. The exact same can also be said for the unfavorable plate, which is reverted into lead dioxide.

Lead-acid batteries providing emergency power for power supplies like the top quality 90-watt Flex ATX PowerSupply aren't as advanced as other chargeable batteries. Their most significant trait is the capacity to provide high input surges, thanks to their exceptional power-to-weight ratio. To avoid any possible leakage of lead, suppliers make certain to seal the battery tight. The battery can last for a number of uses prior to its efficacy reduces.

These batteries may be amongst the few items wherein the use of lead is still welcome. For more details on lead-acid batteries, you can have a look at the simple diagram at Georgia State University's site at
