THE 5 FAQ

AND THE ANSWERS

– Before charging a wet battery, check the electrolyte level and top up if necessary with de-ionised or distilled water to the maximum acid level mark, or 15mm above the upper edge of the plates.

 

Should the battery be removed prior to recharging in order to prevent damage to the vehicle?
Please note the charger type. The operating instructions of the vehicle or the charger manufacturer frequently contain valuable tips regarding battery charging in the vehicle.
In general, a fully automatic charger (charging voltage limitation of 14.8V) is well suited to the charging of a battery installed in a vehicle.

Should your charger have an automatic mode with voltages  >15.9V, it is vital that the battery be separated from the in-board electronics and removed from the vehicle.
In a worst case scenario it is possible that the installed control devices can be destroyed due to overvoltage and the resulting damage would be enormous. Warning! Follow the vehicle manufacturer’s instructions when disconnecting the terminals.


– Batteries may only be charged with direct current. Connect the positive (+) battery terminal to the positive (+)   terminal of the charger, and the negative (-) battery terminal to the negative (-) terminal of the charger.
– Do not switch on the charger until the battery has been disconnected. When charging is completed, switch off the charger before disconnecting the battery.
– It is recommended that the charging current be equal to one tenth of the capacity (e.g. 44Ah divided by 10 = 4.4A charging current).
– The temperature of the acid may not exceed 55°C during charging. If the temperature rises above 55°C, the charging process must be discontinued.
– The fittings must not be opened.
-  Ensure that recharging amounts to 1.2 times the consumed capacity (e.g. consumed capacity 30Ah, recharge 36Ah)
– Charging must be performed in a well-ventilated room.
– Charging is finished when the current drops to 0 or stops falling, or if the automatic charger switches off.


For deep discharged flooded batteries we recommend a charging voltage of 16V (separate the battery from the onboard electronics)!

 

Warning! Oxyhydrogen gas is formed during charging! It is essential that fires, sparks, open flames and smoking be prevented!

 

Running Bull AGM/BackUp: only recharge with a voltage controlled charger (max. 14.8V)! The use of standard, non-voltage controlled chargers will dest­roy the battery through overloading and cause the electrolyte to escape!

In order to achieve full performance and service life, the battery must be fully charged prior to installation (1. + 2.).

 

1. Bike Bull
Preparation. The degassing vent is closed and must be opened before putting into operati­on. Remove the protective cap, or cut off the degassing hose at the end.
Filling. Remove all battery stoppers. Only use special acid (density 1.28 kg/l), which is supplied with the battery in a special plastic container. Fill to the maximum mark and then allow the battery to rest for 30 minutes.
Warning! The acid container with any residual acid should be brought to a hazardous was­te collection point. Acid residues may not enter the sewerage system. Empty acid containers should be disposed of as domestic plastic waste.
Commissioning. In order to reach full performance, once the battery has been filled with acid it must be fully charged prior to installation. In accordance with the instructions for use of the charger and the battery, charging can take place for approx. 5-10 hours at a maximum of one-tenth of battery capacity (Ah).
Battery capacity can be ascertained by means of the DIN number on the individual box. Num­bers 2 and 3, e.g. 509 14 have 9 Ah capacity and therefore require charging current of approx. 0.9 A. After charging, the acid level should be checked and if necessary topped up with demi­neralised water. The battery can then be closed with the stoppers.

Maintenance. Never allow the acid to fall below the minimum level. Only use demineralised water (desalinated or distilled water according to VDE 0510).

Please note! The Bike Bull cannot be installed in a lateral position!

 

2. Bike Bull AGM
Preparation. Remove the battery seal shortly before filling. A slight hissing sound can be heard.
Filling. Only use special acid (density 1.32 kg/l), which is supplied with the battery in a special plastic container. Then allow the battery to rest for 30 minutes. After filling, the battery is closed with the stopper strip and may not be reopened, as this would destroy the battery! Warning! The acid container with any residual acid should be brought to a hazardous was­te collection point. Acid residues may not enter the sewerage system. Empty acid containers should be disposed of as domestic plastic waste.
Commissioning. In order to reach full performance, once the battery has been filled with acid it must be fully charged prior to installation. In accordance with the instructions for use of the charger and the battery, charging can take place for approx. 5-10 hours at a maximum of one-tenth of battery capacity (Ah). Battery capacity can be ascertained by means of the DIN number on the individual box. Numbers 2 and 3, e.g. 518 21 have 18 Ah capacity and therefore require charging current of approx. 1.8 A.
Please note! The Bike Bull AGM cannot be installed in a lateral position!

 

3. Bike Bull GEL, AGM PROfessional
Putting into operation. The battery is fully charged and ready for install. 

Please note: The Bike Bull GEL / Bike Bull AGM PROfessional can be installed in a lateral position!


Use of a voltage controlled Banner Accucharger 6/12V 2A or  12V 3A is recommended.
Warning! Never install a maintenance-free battery (AGM, GEL, AGM PROfessional) in a motorcycle without a regulator, as the maximum voltage may not exceed 14.8 V.

Finding the right battery for use in a motor caravan is not that simple. The text below is intended to provide some explanations regarding the Energy Bull and shed some light on alternative possibilities. 

 

Charging:
Pay close attention to the appropriate dimensions of the feed cable (in order to minimise voltage loss).

The charging voltage for Energy Bull batteries should amount to 14.2 – 14.4V. In order to achieve suitable battery life, the charging current should not amount to more than five times the rated current* (see subsequent calculation).  

All in all, the Energy Bull is a good cyclical battery, which forgives a great deal (as opposed to gel or AGM batteries).  The “disadvantage” of Energy Bull batteries as compared to AGM or gel batteries relates to maintenance. For when an Energy Bull battery is employed, it is imperative that the electrolyte level is checked regularly. During intensive use (camping operation) this should take place on a monthly basis, otherwise quarterly and half-yearly inspections are sufficient.

Gel and AGM batteries are maintenance-free. 

A reasonable price, insensitivity to high temperatures and higher charging voltages are all positive factors in favour of the Energy Bull. 

 

Solar cells
In the case of solar cells make certain that you have a “good“ regulator. Ideally, this should have pulse-width modulation (PWM), temperature compensation and freely selectable parameters (charging voltage...). 

 

Discharging
Inverters require a sizeable amount of discharge current from the battery.
In principle, Energy Bull and gel batteries are unsuitable for high current discharges (>40 times the rated current* for >1min).
Should you require increased amounts of discharge current, we recommend the use of an AGM battery (Running Bull).  
*--> Calculation of the rated current follows!

 

Capacity
It is preferable that the batteries are only operated with low discharge depths.
A lead-acid battery can withstand a certain degree of capacity conversion (= number of conversions of the rated capacity).
The flatter the cycle, the higher the number of possible repeats.
As far as cyclical capability is concerned, if handled with care the gel battery offers roughly twice the service life of an Energy Bull.

 

Degassing
Should the battery be installed inside the vehicle, it must be fitted with a degassing hose with an external outlet. When selecting a battery please choose a type that has a central degassing connection.
--> This allows the gases created during charging (hydrogen and oxygen) to be conducted out of the vehicle.

In a normal operational condition, AGM and gel batteries do not generate any gas (exception: a charger or battery defect). However, for safety reasons a degassing hose must be employed.

Energy Bull batteries generate gases during standard operation and therefore it is essential that a degassing hose is used.


*Rated current calculation

Example: 100Ah (K20) Energy Bull 95751
Rated current (In) = 100 Ah: 20 h = 5A
Maximum charging current = 5 x In = 25A

The "EN types" Power Bull (total height 175 or 190mm) and Running Bull AGM and EFB have their central degassing vent on either the left-hand side (- terminal) or on the right-hand side (+ terminal). The other side is sealed with a removable plug.  

 

If, as in your case, the degassing vent is on the unsuitable side, the plug can be removed. Warning! The plug must then be inserted into the degassing vent on the other side.  

 

Please use a wooden screw with a 5mm diameter for removal of the plug. Insert the screw manually into the small hole in the plug, turn and then pull out both the screw and the plug. There is no need to worry, as the plug cannot be screwed into the battery.  

 

The "EN types" Starting Bull (total height 175 or 190mm) have their central degassing vent on either the left-hand side (- terminal) or on the right-hand side (+ terminal). Please note: there is no change possible, if the degassing vent is on the unsuitable side! 

 

The degassing elbow including the hose (part number: 10300017000) is available at every Banner sales partner.

The Retailer finder shows the nearest Banner sales partner.

 

Insert the degassing hose by using the elbow at the central degassing opening at the side of the battery cover.
No additional work is necessary.
