Deep cycle batteries are designed for long, steady power delivery and can be repeatedly discharged up to 80% of their capacity. They are built with thicker plates for better durability under cyclic use, unlike car batteries that provide short, high-power bursts only for starting engines.
Lifespan varies by type: flooded lead-acid lasts 3–7 years, AGM/gel 4–8 years, and LiFePO4 can last 10–15 years with up to 5,000 cycles. Proper maintenance and charging are critical.
Yes, especially lithium-based types like LiFePO4. They offer high efficiency, greater depth of discharge, longer cycle life, and require less maintenance, making them ideal for solar applications.
