Advantages and Disadvantages of Lead-Acid and Integrated Electroplating Terminal Manufacturers The lead-acid battery is a powerful, reliable and inexpensive rechargeable power source for many devices. Lead acid batteries are suitable for emergency lighting, forklifts, automobiles, golf cars and uninterruptible power supply systems. It offers a moderate life expectancy and high charge retention. They are a popular choice for starter and deep cycle applications. The lead-acid battery is also available in a sealed form, or gel sealed. These types of batteries contain a silica gel that suspends the electrolyte. Unlike the original lead-acid batteries, the gel cells are more resistant to shock and vibration, making them popular in motorcycles and vehicles that operate in a high-vibration environment.
Some models are rolled or flat, and some are made of celluloid. AGM batteries are often used in automobiles, motorcycles and RVs. In addition to their lower cost, AGM batteries are safer to use than flooded lead-acid batteries. AGM batteries have less risk of spilling acid during accidents, and they can be installed at any angle. Another benefit of the AGM battery is that it provides a better charge retention than flooded lead-acid batteries. Using a voltage-regulated charger is recommended. With a voltage-regulated charger, the charger will automatically switch to float mode when the battery reaches the low C-rate. This allows the battery to maintain a full charge, even if it is not being used. Lithium ion is an increasingly popular alternative to lead-acid batteries. These batteries offer large improvements in cycle life and dynamic charge acceptance. However, the cost per kWh is also much higher. While the Li-ion battery has a lower rate of safety incidents, it does not offer the same price-to-capacity ratio as lead-acid. Deep-cycle AGM batteries are a popular choice for off-grid solar power installations.
They are also popular in wind power and amateur robotics installations. Many auto racing vehicles use AGM batteries because they have a high vibration resistance. Their durability makes them a good option for ice monitoring stations in the Arctic. VRLA batteries are also popular, particularly for portable electrical equipment. There are a variety of models, including ones for uninterruptible power supplies, and those for cellular repeater towers. Several manufacturers make these batteries. Although the VRLA battery is a relatively new technology, it has found widespread use in both off-grid and on-grid power systems. For example, a recent 5 series BMW from March 2007 incorporated computer control and devices for braking energy recovery. Also, an AGM deep-cycle marine battery is often preferred for its spill-proof qualities. AGM batteries are not as durable as lithium-based systems. However, their advantages include lighter weight, faster charging and better electrical reliability. Since they are less expensive than flooded lead-acid batteries, they are generally preferred for mobile and mid-range systems. AGM batteries are more readily available than VRLA batteries. Typical uses include marine and RV batteries, as well as starting and deep cycle applications. When comparing the two, it's worth taking into account their differences in charge retention, longevity, safety and environmental considerations.
