Lead Storage Cell Applications

The question asks to identify the type of cell commonly used in both automobiles and inverters. Let's examine the options:

• Mercury cells are typically used in small electronic devices like watches and calculators due to their stable voltage but are not suitable for the high power demands of automobiles or inverters.
• Dry cells, such as zinc-carbon or alkaline batteries, are common in portable devices like flashlights and remote controls. While they provide power, they generally lack the capacity and high discharge rate required for starting a car engine or providing sustained backup power for inverters.
• Lead storage cells, more commonly known as lead-acid batteries, are extensively used in automobiles. They provide the high current needed to start the engine (cranking power) and run electrical accessories. They are also the standard choice for backup power systems like inverters, which convert DC power from batteries into AC power for household appliances during outages. Their rechargeable nature and ability to deliver high power make them ideal for these applications.
• Fuel cells convert chemical energy from a fuel (like hydrogen) into electricity. While they are used in some vehicles and power generation systems, they are not the conventional or widespread choice for typical automobiles or standard home inverters compared to lead storage cells.

Why Lead Storage Cells are Used

Lead storage cells are favoured for automobiles and inverters because:

• High Cranking Power: They can deliver a large surge of current necessary to start a car's engine.
• Rechargeable: They can be recharged by the vehicle's alternator or the inverter's charging system.
• Cost-Effective: Compared to some other battery technologies, lead-acid batteries are relatively inexpensive.
• Robustness: They are durable and can withstand the vibrations and temperature variations found in automobiles.
• Availability: They are widely available and have a well-established infrastructure for manufacturing and recycling.

Therefore, the lead storage cell is the type of cell predominantly used in both automobiles and inverters.
