Supply batteries provide an independent source of power for electrical systems in motorhomes, caravans, boats, and garden cabins. When combined with solar panels, they enable a completely self-sufficient, off-grid setup eliminating the need for external or shore power. Some models are specially developed for medical and mobility applications, such as powering electric wheelchairs in the rehabilitation sector.

Well-known brands like VARTA, Exide, Accurat, and ECTIVE offer a wide selection of supply batteries tailored to different energy needs. These batteries vary by technology and capacity (Ah), allowing users to choose the right solution for their specific requirements.

Key battery types at a glance:

• Flooded lead-acid batteries can be used both for starting engines and powering onboard systems.

• Gel batteries (VRLA) are cycle-resistant and better suited for frequent deep discharges.

• AGM batteries (VRLA) are ideal for high-performance devices with greater energy demands.

• Lithium batteries provide the longest service life and deliver top performance for demanding, long-term use.
