Does the supply battery in a motorhome/caravan differ from a conventional starter battery?
Yes, essential.

A conventional starter battery is, as the name suggests, basically designed to provide a high short energy boost to start the vehicle.

As soon as the engine is running, the vehicle's charging system ensures that the energy taken from the battery is recharged and supplies all other electrical loads.

When compared to running, the starter battery of the Sprinter and the long-term discharge battery would be a marathon runner.


A long-term discharge battery in the hobby/leisure time range is required in order to supply a considerably lower current for the on-board power supply and a large number of electrical/electronic consumers over a longer period of time; it is also discharged and recharged several times.

This means that the technology and components differ significantly from those of a starter battery, so that the use of a starter battery in a cyclic application can lead to premature battery wear or even total battery failure in the first months of operation.


Banner Tip: For a long service life of an on-board battery.

An on-board battery should be discharged to a maximum of 50% charge. In principle, the lower the discharge, the shorter the expected service life. Please ensure immediate and sufficient recharging after each discharge.

Energy Bull - the cycle-proof long-term discharge battery for the hobby/leisure sector. Portable energy for motorhomes, caravans and camping or sailing and electric boats.


Accucharger - for professional battery charging and charge maintenance. Guarantees a safe start, optimum on-board power supply and prolongs the service life of every battery.


BBT Digital Voltmeter DV1 - for voltage testing of all automotive batteries. This is a handy measuring device that measures the battery voltage quickly and reliably. The display is an easy-to-read LCD display.

BOMAG supplier award
BOMAG Supplier Award for Banner!
Banner has been awarded by BOMAG for the fourth time in a row.
Banner wurde zum vierten Mal in Folge von BOMAG ausgezeichnet.

BOMAG, manufacturer of compaction machines, uses extremely vibration and cycle resistant EFB and AGM batteries from Banner.

The world market leader in the soil compaction sector regularly assesses its suppliers in detail and has now awarded batteries from Banner four times in succession: Banner was again able to increase slightly and, with an overall result of over 96%, will again receive the top supplier classification "A-supplier" for the year 2017.

What does a battery with the addition "carbon loaded" actually mean?
Carbon additives allow faster battery charging and improve cycle stability.

The "carbon loaded" technology enables better battery chargeability by incorporating carbon additives in the negative active mass. These carbon particles ensure increased conductivity of the active mass and increased current absorption capacity of the battery.

The result is a significant reduction in loading time!

Furthermore, the use of carbon additives reduces the gassing voltage, thus avoiding potential acid stratification.


It is not without reason that carbon is mentioned in the same breath as the most modern high-tech applications. Due to its low weight and at the same time enormous strength it is used in various areas - from motor sports, over aerospace up to offshore wind power plants... and now also in banner batteries!


Lead-acid batteries benefit from both the exceptionally good conductivity and the thermal properties of this high-tech material. Special carbon additives improve the chargeability and cycle stability of lead-acid batteries and show their full strength, especially in EFB batteries for vehicles with start/stop function or high energy consumption.


The use of carbon is further proof of the innovative power and continuous development work of banners, which is appreciated by renowned car manufacturers around the globe.


What is carbon?
Carbon is a chemical element found in nature in pure form (diamond, graphite) or in compounds such as carbonates, carbon dioxide, crude oil, natural gas and coal. Carbon is able to form complex molecules and forms the basis of all life on earth.

Is it possible that AFB and ECM batteries are also used for start/stop applications or generally for high energy requirements in cars?
This is exactly the same technology as the Banner Running Bull EFB batteries.

There are often different names used on the market for start/stop technology in the battery sector:

AFB = Advanced Flooded Battery
ECM = Enhanced Cyclic Mat
EFB = Enhanced Flooded Battery

AFB and ECM car batteries can be replaced by the Banner Running Bull EFB. In identical housing and identical performance class.
