Gel batteries have become an alternative to classic lead-acid batteries. Unlike them, gel models are maintenance-free batteries. This means that they do not require electrolyte replenishment. Their advantage is the tight case and the electrolyte in gel form. This prevents leakage, so the battery can be held in any position and is more resistant to shocks.

Gel battery durability
One of the biggest advantages of gel batteries is their durability. Of all the types available on the market, this type is the longest-lasting, as it can last up to twelve years with proper use. Importantly, gel batteries are also more resistant to changing and extreme weather conditions.

Automatic discharge (25 °C)
Gel batteries can be stored for many months without the need for charging. Their capacity drops to:

91% after 3 months

82% after 6 months

64% after 9 months

Applications of gel batteries
Gel batteries are used, among other things, in motorcycles, golf carts or lawn mowers. They are also used in emergency power supplies, photovoltaic installations, alarm systems and electric toys. These batteries are also found in cars with a large number of electrical devices, e.g. campers. These are then not used to start the car, but to power electronic devices.

Gel battery charger
In order for the charger to work properly and not damage the battery, it must have the correct current and voltage. These values ​​will differ at different stages of charging, so it is worth choosing an automatic charger that not only adjusts the appropriate charging current and voltage, but also turns off when the battery is fully charged.
