They are heavier than other types and require regular maintenance, like checking water levels in flooded lead-acid versions. They’re reliable but may have a shorter lifespan compared to AGM or lithium-ion.

Lead-acid batteries function using chemical reactions between lead plates and sulfuric acid. When the battery discharges, lead sulfate forms on the plates. During charging, this process is reversed, returning the lead and sulfuric acid to their original states. The capacity of a lead-acid battery is often measured in amp-hours (Ah), reflecting the amount of current it can provide over time. The lifespan depends on factors like usage, charging habits, and temperature.

• AGM (Absorbed Glass Mat) Batteries: AGM batteries are an evolution of lead-acid technology. They use a fiberglass mat to absorb the electrolyte, making them spill-proof and more resistant to vibration. AGM batteries are generally maintenance-free and offer a longer lifespan than flooded lead-acid batteries. They are great for situations where the battery is not easily accessible.

AGM batteries provide superior performance in applications requiring high power output, such as starting engines. They are sealed, preventing leaks and making them a safer option. Because of their design, they can be mounted in various positions without the risk of spillage. AGM batteries also have a lower self-discharge rate, which means they lose less charge when not in use. This makes them ideal for seasonal tools. The initial cost is higher than traditional lead-acid, but the benefits in performance and longevity often outweigh the investment.

• Lithium-ion Batteries: Lithium-ion batteries represent the cutting edge of battery technology. They are lightweight, have a high energy density, and can be charged and discharged many times without a significant loss of performance. They typically last the longest and have the highest upfront cost.

Lithium-ion batteries operate via the movement of lithium ions between a positive electrode (cathode) and a negative electrode (anode). They are characterized by a flat discharge curve, meaning they provide consistent power until the battery is nearly depleted. They also charge faster and weigh significantly less than their lead-acid counterparts. They offer a greater depth of discharge (DoD) than lead-acid batteries, which means you can use more of the battery’s capacity before recharging. Because of their performance and longevity, they are becoming increasingly popular in outdoor power equipment.
