Gel batteries are a type of valve‑regulated lead‑acid (VRLA) battery that uses a silica‑based gel electrolyte instead of a free‑flowing liquid. This gel immobilizes the electrolyte, making the battery spill‑proof, orientation‑flexible, and resistant to acid stratification. During charge and discharge, the gel structure helps recombine oxygen internally, which minimizes water loss and eliminates the need for regular water refilling. These characteristics make gel batteries particularly suitable for deep‑cycle solar applications, such as off‑grid homes, cabins, and RVs.
