Deep Cycle Batteries

Deep cycle batteries are designed to withstand many cycles of discharge and recharging. They are built with thicker plate structures, better-quality electrical connections, and often more reliable separators. They also have a greater buffer capacity against discharge deep into the battery's interior. Gel batteries use a non-solid gel electrolyte instead of the liquid electrolyte found in typical lead-acid batteries. The gel provides several benefits over the liquid-electrolyte model.

A lead-acid deep discharge battery might have an expected service life of 3 to 5 years (8000 to 14400 charge/discharge cycles). They provide reliable power in solar systems and help overcome two key problems associated with direct-coupled solar panels: supply limitation during times of low sunlight and overcharging when the sun shines too brightly. The cycle life drop-off starts at around the 400th cycle.
