What is a significant feature of gel or sealed batteries?

Gel or sealed batteries, commonly used in various applications including mobility devices, are designed to provide enhanced safety and convenience. A significant feature of these batteries is their gelled electrolyte, which eliminates the free liquid found in traditional wet-cell batteries. This design not only makes them spill-proof but also reduces the risk of leakage and corrosion.

As a result, gel batteries require less frequent maintenance than standard wet-cell batteries. Users do not need to check water levels regularly, which can save time and prevent potential issues associated with maintenance. The sealed design further protects against contamination and helps prolong the life of the battery.

Moreover, these batteries are often considered safer for use in environments where spills could be hazardous, making them suitable for both indoor and outdoor applications. In summary, their safety, coupled with reduced maintenance requirements, makes gel or sealed batteries a popular choice in assistive technology and mobility devices.
