What is a lead-acid accumulator?

The lead-acid battery - also known colloquially as a lead-acid accumulator - is a reliable and inexpensive power storage device. Lead-acid batteries have a low self-discharge rate and are maintenance-free. With regular care, a very long service life is achieved. Lead-acid batteries are used in hazard alarm systems, UPS systems, emergency lighting systems, solar technology and many other areas.

What types of lead-acid batteries are there?

Lead batteries can be divided into closed and sealed types. Sealed lead-acid batteries are often referred to as valve-regulated lead-acid batteries (VRLA batteries). They are suitable for transport and storage in any position. This is made possible by a built-in pressure relief valve that regulates the internal pressure. Special care is required with closed lead batteries. This is because they contain liquid sulphuric acid and must be regularly topped up with distilled water. This ensures optimum conductivity.
Sealed lead batteries are considered maintenance-free as they contain electrolytes in bound form. These batteries are available in three different technologies: Lead-fleece batteries (AGM batteries), pure lead batteries and lead-gel batteries. The electrolytes are fixed differently in each of these types.

The AGM battery

The lead-fleece battery is a sealed, valve-regulated battery. It is also known as an AGM battery (Absorbent Glass Mat). Thanks to the built-in glass fibre fleece, the AGM battery is protected against electrolyte (acid) leakage - regardless of the position in which it is used. For the back-up and security sector and for many other applications, you will find AGM batteries from various manufacturers: between 2 V and 12 V and 0.8 Ah to 200 Ah, some with VdS approval as VdS batteries. You can also test our own brands SSB Battery and SUN Battery. These stand for maximum quality at a fair price.

We offer AGM batteries from well-known manufacturers:

Where are lead-acid batteries used?

The areas of application for lead-acid batteries can be divided into mobile and stationary applications.
Stationary lead batteries are generally used as backup batteries for an emergency power supply. The battery is intended to replace the power supply for a certain period of time in the event of a failure.
Stationary lead-acid batteries are usually used in the following areas:

Mobile lead batteries are used as traction and starter batteries. The lead-acid batteries are used in electric vehicles as traction and in combustion engines as starting support, but also as a power source for the alternator if the engine fails.
Mobile lead-acid batteries are usually used in the following areas:

What is the service life of lead-acid batteries?

If they are stored correctly, used appropriately and maintained regularly, the service life of lead-acid batteries can be more than ten years. The service life is strongly influenced by the way they are used. Each charging and discharging cycle consumes some of the battery's active material. The number of possible cycles varies depending on the type of lead-acid battery. Natural ageing is unavoidable. They should therefore be regarded as consumables.

How is a lead-acid battery disposed of?

Lead batteries contain substances that are harmful to people and the environment. It is therefore important that they are disposed of properly. Residual waste bins and recycling bins are not suitable for this purpose. Instead, they must be taken to a designated disposal centre. For larger quantities, they can be collected using special disposal boxes. If lead-acid batteries are disposed of correctly - for example via the seller of the batteries - they can be almost 100% recycled. The used lead is recovered and fed into the production cycle of new lead batteries. Battery-Kutter will be happy to collect and recycle your lead batteries free of charge.
