Yes, in the case of many battery types.


The Power Bull Europa types (total heights 175 or 190 mm), as well as the Running Bull AGM and EFB batteries have an opening for the central degassing connection in the battery lid, which is either on the left-hand side (-terminal side in batteries with connection 0) or on the right (+terminal side in batteries with connection 0).

If in your case, the side of the degassing opening is unsuitable, the white plug can be removed, but must then be reinserted on the other side in the degasification duct (in order to prevent the escape of oxyhydrogen gas).


In order to remove the plug, please use a wood screw with a diameter of approx. 5 mm. There is no need for concern, as the plug cannot be pushed into the battery. 


P.S. The Starting Bull Europa types (total heights 175 or 190 mm) have an opening for the central degassing connection on the right-hand side (+terminal side in batteries with connection 0, -terminal side with connection 1). Please note that no change of degassing side is possible.   
The current installation situation in brief:
For all the batteries in the latest BMW and Mercedes-Benz vehicles, degassing is on the + terminal side and therefore on the right in the case of batteries with connection 0. 
In currently manufactured VW Group vehicles all batteries are degassed on the - terminal side and therefore on the left in the case of batteries with connection 0.

Yes, always!
We prescribe the obligatory employment of a degassing hose (Part Number 1030001700 with a hose length of 90 cm including an elbow) when installing all types of lead-acid battery in the interior/passenger compartment.

Some vehicles are equipped with a degassing hose with an angled elbow to drain off the battery gases. If this applies to a vehicle, the hose must be inserted into the appropriate vent opening of the battery via the elbow. If a degassing opening is present on the other side, it must be closed with a closing plug!
In case of replacement of closing plugs/stoppers for battery degassing or degassing hose, please contact your Banner sales partner/sales consultant.


For your own safety, please constantly employ protective eyewear when handling lead-acid batteries.

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.


– In view of the sensitive electronic components in the vehicle, as a rule starting assistance should only be provided by means of a Banner Booster.
– Starting assistance from vehicle to vehicle can lead to voltage peaks during disconnection, which can damage or even destroy vehicle electronic systems.
– Therefore, it is essential that the following procedure be strictly observed when using starter cables!
– Standardised starter cables (e.g. in accordance with DIN 72 553) should always be used for giving starting assistance.
– Observe the instructions for use of the starter cables.
– Only connect batteries with the same nominal voltage.
– When connecting the terminals, both vehicle engines must be switched off!
First connect the two positive terminals 1 with 2. Then connect the negative terminal of the assisting vehicle 3 with 4, the blank metallic point on the vehicle needing assistance, away from the battery. (Observe the instructions of the vehicle manufacturer.)
– Now start the vehicle needing assistance for a maximum of 15 seconds. Do not start the assisting vehicle.
– When disconnecting the terminals, remove the cables in the reverse sequence to the above.

– 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!
