Autonomous power supply and reliability of power sources are important aspects for many users. There are many types of batteries on the market, but AGM batteries deserve special attention due to their unique characteristics and advantages. In this article, we will look at AGM technology, compare it with conventional lead-acid batteries and LiFePO4 batteries, and pay special attention to the Redbo 6-RB-100 12V 100Ah model .
What is an AGM battery?
AGM (Absorbent Glass Mat) is a lead-acid battery technology that uses an absorbent glass mat to hold the electrolyte. Unlike conventional lead-acid batteries, AGM batteries do not have a liquid electrolyte, making them safer and more reliable.
How AGM batteries work
AGM batteries consist of glass mats sandwiched between lead plates that absorb and hold the electrolyte. This provides several key benefits:
- No leakage : The electrolyte is tightly held in the glass mats, preventing leakage.
- Minimal maintenance : AGM batteries do not require regular water topping up.
- High vibration resistance : Due to their dense structure, these batteries are more resistant to mechanical damage and vibration.
Comparison with conventional lead-acid batteries
Conventional lead acid batteries are widely used, but they have a number of limitations compared to AGM batteries.
Advantages of AGM batteries :
- Higher energy density : AGM batteries can store more energy in the same size.
- Fast Charging : Due to lower internal resistance, AGM batteries charge faster.
- Safety : The absence of liquid electrolyte makes them safer to use.
- Запуск двигателя: AGM аккумуляторы могут использоваться для запуска двигателей автомобилей благодаря их способности обеспечивать высокие пусковые токи. Аккумулятор Redbo 6-RB-100 12V 100Ah способен обеспечить достаточный ток для запуска двигателя большинства автомобилей. Пусковой ток (CCA – Cold Cranking Amps) для такого аккумулятора обычно составляет несколько сотен ампер, что вполне достаточно для запуска стандартного автомобильного двигателя.
Недостатки AGM-аккумуляторов:
- Стоимость: AGM-аккумуляторы обычно дороже обычных свинцово-кислотных аккумуляторов.
- Чувствительность к перезаряду: Перезарядка может сократить срок службы AGM-аккумулятора.
Сравнение с аккумуляторами LiFePO4
LiFePO4 (литий-железо-фосфатные) аккумуляторы становятся всё популярнее благодаря своим выдающимся характеристикам.
Преимущества AGM-аккумуляторов перед LiFePO4:
- Стоимость: AGM-аккумуляторы обычно дешевле LiFePO4.
- Широкая доступность: AGM-аккумуляторы доступны в большем количестве форматов и емкостей.
- Безопасность: при разгерметизации нет белого едкого дыма.
Недостатки AGM-аккумуляторов по сравнению с LiFePO4:
- Циклы заряда-разряда: количество циклов многократно превосходит AGM-аккумуляторы, что актуально при использовании этих аккумуляторов в режиме “Автономный источник энергии”, т.е. днём заряжается от солнечных панелей, ночью разряжается. В режиме “Резервного источника питания” этот недостаток не так актуален.
- Срок службы: LiFePO4-аккумуляторы имеют гораздо больший срок службы (до 10 лет и более).
- Вес и размер: LiFePO4-аккумуляторы легче и компактнее при той же емкости.
- Более глубокий разряд: LiFePO4-аккумуляторы позволяют использовать больше ёмкости без повреждения аккумулятора.

The difference between starter and traction batteries
Starter batteries :
- Purpose : Used to start engines, providing short-term high current.
- Design : They have a larger number of thin plates, which allows them to quickly deliver high current.
- Advantages : High starting current (CCA), fast discharge for engine starting.
- Application examples : Cars, motorcycles, boats, generators.
- Disadvantages : Not designed for deep discharge; use under constant deep discharge conditions can quickly destroy them.
Traction batteries :
- Purpose : Used for long-term power supply of equipment, providing stable current over a long period of time.
- Design : They have a smaller number of thick plates, which allows them to withstand multiple deep discharge and charge cycles.
- Advantages : High capacity, deep discharge capability, long service life under cyclic use.
- Application examples : Electric vehicles (golf carts, electric cars), solar and wind energy systems, uninterruptible power supply systems (UPS).
- Disadvantages : Low starting current compared to starter batteries, slower discharge.
What type of battery is Redbo 6-RB-100 12V 100Ah?
AGM batteries can be either starting or traction batteries, depending on their design and purpose. The Redbo 6-RB-100 12V 100Ah battery has characteristics that can be suitable for both engine starting and traction applications. However, it is positioned more as a traction battery.
Conclusion
AGM batteries, such as the Redbo 6-RB-100 12V 100Ah , offer many advantages over conventional lead-acid batteries and are a great alternative to LiFePO4 batteries when a balance between cost and performance is required.
