Stable source of energyWhen carrying out your daily activities or when you are at work, you are bound to use devices that need electricity to function efficiently. Some of these draw power from the mains and only use a battery when there is no electricity available. It will then function very efficiently and enjoy a much longer service life of up to 10 years as an emergency power supply in buffer operation, e.g. for UPS, alarm systems or emergency lighting. For others, a battery is sufficient for operation, but this is a cyclical operation involving constant charging and discharging of the battery, e.g. electronic toys, quads, wheelchairs and golf carts.Safe and maintenance-freeWe design our batteries according to the latest AGM technology, which allows them to work longer, thanks to the slow discharge process. The AGM battery's unquestionable advantage is that it is sealed and shock-resistant, so it is ideal for use in enclosed spaces, is gas-free, leak-proof and has a high mechanical resistance. Equipment powered in this way will operate faultlessly for a long time. Our batteries are maintenance-free throughout their entire service life and can operate for up to 10 years.How to charge an AGM battery correctly? AGM batteries need to be charged using the so-called constant-voltage method, first with a constant current and then with a constant voltage. We offer chargers, with a switch, that are ideal for this type of battery. In this way, you can avoid the risk of destroying the battery through inappropriate charging.Take care of your batteryPlease note that proper use and care of the AGM battery is very important for its service life. Frequent and deep discharges will certainly not have a positive effect on its performance. To enjoy a long battery life try to:avoid deep discharge, ensure correct charging - do not overcharge the battery, avoid very low temperatures and prolonged exposure to high temperatures.
Your stable energy source for everyday and holidayWhile performing daily activities or being at work, you certainly use devices that need electricity to function properly. Some of them draw power from the grid and are exposed to voltage fluctuations or power outages. For smooth operation, it is necessary to have an emergency power source. These include:- alarm and monitoring systems,- emergency lighting,- medical equipment,- scales and cash registers.Others have internal combustion engines and rely solely on battery power. Among them are:- quads,- forklifts,- scooters,- boats,- campers.To provide them with a stable and safe power source, we have prepared a wide range of solutions. Check out Qoltec's offer of AGM batteries and choose the variant that best suits your needs.Don't be caught off guard. Find out how an AGM battery performs at its bestWondering where our battery is best applied? As a primary power source or as a backup power supply for devices usually connected to the electrical grid? We'll answer honestly: we recommend using the 20Ah AGM battery for buffer operation. Why?Buffer operation mode is recommended for AGM technologyThe battery used will function very efficiently and enjoy a long lifespan - up to 10 years, as emergency power in buffer operation e.g., for UPS power supplies, in alarm systems, emergency lighting, or internal combustion vehicles.What is AGM technology?The AGM (Absorbent Glass Mat) technology, in which our batteries are designed, means that the electrolyte contained in the battery is absorbed by special mats made of highly porous glass fiber placed between lead plates covered with mats. This solution allows for longer battery life, thanks to the slow discharge process. Reliable from every angle - the safety of your AGM battery-powered devicesFeel safe the advantage of AGM batteries is undoubtedly their maintenance-free nature, and their reliability is maintained for a long time. This is possible thanks to a construction characterized by:- enclosure sealing,- shock resistance,- the ability to be mounted in various positions.When you buy a 20Ah AGM battery, you receive full reliability guarantee. Do you want your equipment to work at full capacity without limitations? Now you can be sure it will receive the necessary energy without compromise.Long-lasting battery life - enjoy energy for much longer!Another advantage of our batteries is their maintenance-free lifespan, allowing them to work up to 10 years!This is possible thanks to the use of the highest quality components, including pure (non-recycled) lead. It is free from any impurities that could reduce the battery's capacity. Meanwhile, the housing is designed with high-quality material in mind to maximize the battery's lifespan by protecting its interior.Take care of your battery, and it will serve you for many yearsRemember, proper use and care of the AGM battery are crucial for its lifespan. Frequent and deep discharge will certainly not positively affect its efficiency. To enjoy a long battery life, try to:- avoid deep discharge,- ensure proper charging - do not charge the battery with too high a current,- avoid very low temperatures or prolonged exposure to high temperatures- use a charger suitable for the specific type of battery.How to properly charge an AGM battery for its longest lifespan?AGM batteries require charging with the so-called constant-voltage method, initially with direct current, and then with constant voltage. This way, you can avoid the risk of damaging it through improper charging.
