Choosing the right supply battery for your application
Supply Batteries
Supply batteries play a central role in numerous applications, ranging from recreational vehicles to industrial machinery. At Batterie Siems, we offer a wide range of supply batteries, including AGM, lead-acid, and GEL batteries. They are perfectly suited for boats, ships, forklifts, rehab devices, solar and photovoltaic systems, as well as motorhomes.
- There are three main types of supply batteries: AGM, lead-acid, and GEL batteries. AGM batteries are maintenance-free and robust, lead-acid batteries offer a good price-performance ratio, and GEL batteries are leak-proof and long-lasting.
- Supply batteries provide consistent power over long periods and are ideal for applications such as solar systems, motorhomes, boats, and off-grid solutions. They are designed for cyclic loads and are perfectly suited for operating consumers without a continuous charging source.
- Supply batteries are designed for minimal maintenance while offering high capacity and a long service life.
What are supply batteries?
Vorteile unserer Versorgungsbatterien
For seasonal applications, such as in motorhomes or boats, stable capacity is crucial to ensure reliable operation even during long periods of inactivity or high energy demand. AGM and GEL batteries perform particularly well in this regard thanks to their low self-discharge and maintenance-free design. Feel free to contact our experts if you have further questions or specific requirements.
AGM batteries: versatile and robust
These batteries are maintenance-free and offer high cycle stability as well as low self-discharge, making them ideal for use in a wide range of applications.
- Boats and ships: AGM batteries are particularly suitable for maritime applications, as they are shock-resistant and leak-proof.
- Forklifts: Thanks to their high capacity and long service life, AGM batteries are ideal for use in forklifts.
- Motorhomes: They provide reliable power supply for long journeys and are extremely resistant to vibrations and shocks.
Lead-acid batteries: proven technology
- Solar and photovoltaic systems: Lead-acid batteries are a cost-effective solution for storing solar energy.
- Rehab devices: These batteries provide the reliability and performance required for medical equipment.
GEL batteries: safe and high-performance

Frequently asked questions about our supply batteries
Supply batteries are batteries that are specifically designed to reliably provide energy over long periods of time. They are commonly used in motorhomes, boats, solar systems, and other applications where a continuous power supply is required.
Supply batteries are designed to deliver steady and long-lasting power, whereas starter batteries are intended to provide short bursts of high current for starting engines.
AGM batteries are maintenance-free and have high cycle stability. Lead-acid batteries offer good value for money. GEL batteries are leak-proof and particularly durable.
AGM and GEL batteries are excellent options for motorhomes, as they are maintenance-free and long-lasting.
The service life of supply batteries varies depending on the type and usage, but typically ranges between 5 and 15 years.
Yes, AGM batteries are ideal for use in boats, as they are shock-resistant and leak-proof.
Yes, GEL batteries are maintenance-free and do not require regular checking of the electrolyte level.
Both lead-acid and GEL batteries are good options for solar and photovoltaic systems, with GEL batteries often being preferred due to their durability and safety.
Supply batteries should be charged with a suitable charger that is matched to the specific requirements of the battery. Regular and complete charging is important to maximize battery life.
Yes, supply batteries can be connected in series or in parallel to achieve the desired voltage or capacity. It is important to use batteries of the same type and age.

What are supply batteries?
Supply batteries, also known as deep-cycle batteries, are specifically designed to deliver continuous power over long periods of time. Unlike starter batteries, which provide a short burst of high energy to start an engine, supply batteries can be deeply discharged and recharged without significantly affecting their service life.
