Gel batteries have become an alternative to classic lead-acid batteries. Unlike the latter, gel batteries are maintenance-free. This means that they do not require electrolyte topping up. Gel batteries have a hermetically sealed case and the electrolyte is in gel form, which ensures that it will not leak, so the battery can be held in any position and is more resistant to shocks. One of the biggest advantages of gel batteries is their service life. Importantly, gel batteries are also more resistant to changing and extreme weather conditions and have a low self-discharge rate. Gel batteries are used, for example, in motorcycles, golf carts and lawn mowers. They are also used in uninterruptible power supplies, photovoltaic devices, alarm systems and electric toys.
