The most common type of lead-acid battery is the flooded battery, also known as a wet-cell battery. These batteries have a liquid electrolyte that is free to move around the battery cells. Another type of lead-acid battery is the sealed battery, which is also known as a valve-regulated lead-acid (VRLA) battery.
The answer is YES. Lead-acid is the oldest rechargeable battery in existence. Invented by the French physician Gaston Planté in 1859, lead-acid was the first rechargeable battery for commercial use. 150 years later, we still have no cost-effective alternatives for cars, wheelchairs, scooters, golf carts and UPS systems.
Lead Acid - This battery produces a voltage by the reaction of lead and lead oxide with a diluted sulfuric acid electrolyte wet cell. When a load is connected across the negative and positive electrodes, the negative lead electrode reacts with the sulfate in the electrolyte to form lead sulfate.

The lead-acid battery occupies the lowest energy density amongst current rechargeable batteries. As a result, this makes it unsuitable for mobile or handheld devices
Never replace your Nickel-Cadmium (NiCad) batteries with Sealed Lead-Acid batteries! The charging requirements are very different and they require completely different circuit boards.
Shallow Depth of Discharge: Lead acid batteries commonly have a depth of discharge (DoD) of around 50%, which means you can only use 50% of the electricity stored in
cycle. The voltage of a lead-acid battery, on the other hand, decreases much more notice-ably as it is used. By measuring the voltage of a lead-acid battery, its state of charge can be accurately determined. Figures 6 and 7show the discharge voltage curves of nickel-cadmium and lead-acid batteries.

It's easy to spot Nickel-Cadmium batteries as they are cylindrically shaped often looking like AA batteries. Conversely, Sealed Lead-Acid batteries are block shaped. The best device to test your batteries is a battery tester. This device will actually use the batteries existing power when giving a reading. Another option is a multi-meter.
It is important that they are disposed of properly at the end of their life. They are subject to special regulation and requirements that are very different from lead-acid batteries. Indeed, NiCd batteries cannot even be packed for disposal together with lead-acid batteries.
Lining up lead-acid and nickel-cadmium we discover the following according to Technopedia: Nickel-cadmium batteries have great energy density, are more compact, and recycle longer. Both nickel-cadmium and deep-cycle lead-acid batteries can tolerate deep discharges. But lead-acid self-discharges at a rate of 6% per month, compared to NiCad's 20%.
Most of the inherent failures of lead-acid batteries, particularly lead-calcium, are due to the degradation of the positive plates because of either paste shedding or corrosion. The NiCd batteries electrolyte, which is potassium hydroxide (KOH), does not corrode the plates and consequently there is no sudden end-of-life.
Nickel-cadmium (NiCd) batteries also use potassium hydroxide as their electrolyte. The electrolyte in nickel-cadmium batteries is an alkaline electrolyte. Most nickel-cadmium NiCd batteries are cylindrical. Several layers of positive and negative electrode materials are wound into a roll.
Good ol' lead-acid batteries have been around since the 19th century, and they're still a popular choice for certain applications today, like car batteries and backup power systems.
