HOBBY BATTERIES FOR ENGINE START AND ON-BOARD POWER
ELECTRICITY TO GO!
The on board power for recreation and leisure time
The Banner Energy Bull and Traction Bloc Bull are specialised, professional batteries that stand out from the rest and like professionals, these also do their job: perfectly suited to their field of application and uncompromising in their quality. Among other things, they provide portable energy for sailing and electric boats, yachts, camper vans and motor homes, camping/caravanning and the solar sector.
Banner tip: With its solid cold start values, the Energy Bull DUAL POWER can now of course also be recommended as a starter battery primarily for use in motor boats and motor yachts - almost always spring to autumn operation. For engine starting, especially in motorhomes for winter camping, it is best to continue using a starter battery such as the Running Bull EFB-PROfessional/AGM or the Power Bull. The Energy Bull DUAL POWER then continues to be used as an on-board battery in a dual battery system.
Leading motor home manufacturers such as Knaus Tabbert Reisemobile rely on the best Banner batteries from the Running Bull series as their original equipment.

What battery do I need for my motorhome or boat?
You can calculate the capacity requirements of motorhome and boat batteries as on-board power supplies yourself. Here you can see an example of how to determine the power requirement for your use.
Required battery: Energy Bull 96801 K5 = 180 Ah
If the average power-on time is approx. 5 hours, the K5 is used. If it’s approx. 20 hours, the K20 is used and if approx. 100 hours, the K100. With conventional batteries, the safety factor (to prevent deep discharges) should normally be 1.7 (1.3 with recombination batteries, i.e. AGM and gel).

*1 nautical mile = 1.852 kilometres. Here’s a relatively simple formula for novice seamen to understand how far a boat has travelled: Double the nautical miles, next subtract 10%.
This is how you get the approximate distance in kilometres.
Please note: Approx. 50-60 nautical miles of distance per day corresponds to 10-12 hours per day of sailing time at an average speed of 5 knots (and that is fast, for all you non-sailors out there it’s 9.26 km/h to be precise)!
Advantages Traction Bull Bloc AGM
Optimal for the operation of powerful, current-intensive consumers due to good high-current characteristics - inverters, coffee machines, hobs, water heaters, ... almost always require high discharge currents. In short, for "maximum power and maximum currents", please consider the storage capacity and current delivery capability for AGM batteries.
Advantages Traction Bull Bloc GEL
Ideal for operating smaller consumers, so do not use with very high discharge currents - battery monitors, marten deterrents, surveillance cameras, USB sockets, .... Always optimal when the power drawn is moderate but is drawn continuously over a longer period of time.
General note
For both battery technologies, it is essential to observe: Never remove the entire nominal capacity from the battery! Banner recommendation: max. 50% depth of discharge (DoD)
Banner tip: In the camping/caravan sector with limited payload, always take the battery weight into account!
Electricity to go on lead-acid technology - wet, AGM and GEL.
Here are the facts briefly noted and visualised, all data always based on 50% depth of discharge (DoD).
We quote cycles that can be applied to a period of time by each individual according to his or her own requirements profile. But it is not serious to simply "confuse" with x years of service life.
In our case, a cycle (partial cycle, not full cycle) means a partial discharge of the battery to 50% residual capacity and subsequent full charge to 100% state of charge.
Conventional wet battery - Energy Bull - up to 270 cycles - for on-board power supply (and as a new DUAL POWER battery now also suitable for engine starting)!
AGM/Fleece battery - Traction Bull Bloc AGM deep cycle - up to 680 cycles - ideal for on-board power supply.
Gel battery - Traction Bull Bloc GEL cycle - up to 980 cycles - optimal for on-board power supply.
Good to know!
Another advantage of lead-acid batteries that is often overlooked:
High-density materials, such as lead, are the ideal and optimal ballast weight for the keel of a sailing boat or yacht! Because a counterweight to the wind pressure in the sail is always necessary! The so-called keel bomb made of lead or an iron alloy, if available, can then be designed to be somewhat lighter.
Nature lovers and outdoor enthusiasts are people with a particularly strong connection to nature and can feel good about the fact that the batteries in use are recycled and reused. Not disposed of and landfilled!
Battery recycling for a clean environment!
No other battery technology is as optimally recyclable, sustainable and environmentally friendly as the lead-acid-based technology used in Energy Bull and Traction Bull.
Lead-acid batteries from Banner are European recycling champions!
In fact, the recycling rate is 100%, which is higher than for aluminium cans, glass or waste paper!
Good to know.
A motor home almost always uses a combination of starter batteries for starting the engine and long-term discharge batteries for supplying all additional electrical/electronic consumers (e.g. lights, fridge, entertainment system, etc.).
Please note: Despite a higher purchase price, a battery with higher cycle stability can pay off over its lifetime, but this always depends on the particular application. In addition, buyers can save on costs for often complex installation and removal including new purchase and transportation.
Banner tip: When operating 230 V appliances (e.g. hairdryer, kettle or coffee maker) via an inverter, add another approx. 15% to the wattage because this is how much energy is lost when the inverter is operated. An inverter (also called a power inverter or rotary converter) is an electrical device that converts direct current into alternating current.
