THE 5 FAQ

AND THE ANSWERS

– 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.

A fully charged battery can be stored till the open circuit voltage is 12,50V.

Depending on the temperature batteries can be stored up to 12 months without recharging.

The colder the storage temperature the lower the self discharging rate.


In order to be rather safe than sorry, it is advisable to check the off-load voltage of the battery after roughly three months. If this is < 12.50V, the battery should be recharged, while with < 12.60V another check after about a month is to be recommended.    

 

When recharging outdoors, care should be taken that the battery temperature must rise to over 0°C in order that it will accept a charge.

 

If recharging is required, the battery can be removed and left to “thaw” in a room with >0°C. Alternatively, the charger can be connected to the battery for several days, as the charge energy is employed initially to heat up the battery.

 

There is no need for concern, as a fully charged lead-acid battery only freezes at approx. minus 70°C. However, a discharged battery (off-load voltage = 12.0V) freezes at just a few degrees below zero.

 

A few tips to note:
- Prior to recharging top up missing electrolyte with distilled or demineralized water to the maximum level.
- Before winter decommissioning, recharge the battery (separately) until the charger gauge shows that it is fully charged.
- Ensure that surfaces of the battery are dry and remain so.    
- If the battery is removed from the vehicle, it should be stored in a dry place that is as cool as possible (fully charged). 
- When storing the battery, provide it with short circuit protection.
- Fully charge the battery prior to installation in the vehicle and contact with its electrical system.
- Last, and most importantly, always use protective eyewear when handling lead-acid batteries.  

 

Suitable chargers are available for automatic charge retention (all Banner Accucharger devices). Such chargers can remain connected to the battery throughout the winter without causing it any damage

– 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!

Banner recommends only fit batterie with an open circuit voltage > 12,50V inside a vehicle.

 

– Before fitting or removing the battery, switch off the engine and all power users.
– Avoid short circuits due to tools.
– When removing the battery, first disconnect the negative (-) terminal and then the positive (+) terminal.
– Prior to fitting the battery, clean the battery compartment.
– Ensure that the battery is secured tightly.
– Clean terminals and battery clips and lubricate lightly with acid-free grease.
– When fitting the battery, first connect the positive (+) terminal and then the negative (-) terminal. Ensure that the clips are secured.

 

Warning! Always follow the instructions (operating or maintenance) of the vehicle manufacturer!

It is often the case that in the vehicle discharges exceed charging levels, which leads to a “negative charging balance” that makes life extremely difficult for any battery.

 

In addition, particularly in winter, numerous consumers burden the vehicle's electrical system and the starter battery. The low temperatures also play a role, as they not only have an effect upon the engine oil, which becomes viscous and causes increased friction forces in the engine, but also impact the chemical reactions and charging capacity of modern Ca/Ca batteries.

 

A further negative influence derives from the fact that lead-acid batteries can only absorb a charge when they have a temperature of >0°C. Therefore, at the start of a drive all the available charging energy is used to heat the battery (electro-chemical process). Unfortunately, once the battery has reached the charging range, the drive is frequently over and the majority of car owners switch off the engine.

 

It should be noted that depending on the vehicle type and the location of the battery, the temperature range needed for charge intake is only attained after a journey of at least 20 km. However, this problem can be eased through recharging with an external charger.
