TIPS AND TRICKS

CONSEQUENCES OF INSTALLING THE WRONG BATTERY

 

Vehicles with a start-stop function place higher demands on the starter battery used – this applies to simpler start-stop systems with an EFB battery as well as to sophisticated start-stop systems with an AGM battery and energy recovery.

The technology and components of a start-stop battery differ significantly from those of a conventional starter battery.

Conventional battery (wet-cell battery) vs. start-stop battery

 

A conventional starter battery is designed to provide a high short energy boost for starting up the engine. While the engine is running, the charging system then recharges the energy taken from the battery. In contrast, a start-stop battery is responsible for much more than just starting up the engine. The various consumers of the vehicle are supplied with energy while the vehicle is stationary and the engine is not running. When the engine is stopped, the complete electronic system power supply, including the next starting procedure, must nevertheless be ensured. 

Consequences for installing the wrong battery 

 

If a conventional wet-cell battery is installed in a vehicle with start-stop technology by mistake, due to an allocation error – or incorrect cost awareness – a wide variety of errors and problems can arise:

Batterieausfall

Battery breakdown

or total failure

 

Depending on the driving profile (short distance, stop-and-go, etc.), a conventional starter battery will be defective within a few months due to the extremely high cyclic load caused by the engine start-stop function.

Start-Stopp-System

Failure

Start-stop system

 

Selecting the wrong battery may also cause the start-stop system to fail. As a result, the engine is rarely or never switched off when the vehicle is at a standstill (e.g. at a traffic light). 

Batterie Warnung

Failure of various vehicle functions

 

An incorrect battery can cause a number of various functional failures. This means that certain consumers in the car can no longer be used or only be used to a limited extent. For example, the air conditioning system only runs at the lowest level or seat heating cannot be activated.

Ärger Auto

Anger and loss of time

 

 

Possible loss of time, waiting for help, delays and scheduling problems can all come from a battery failure. These inconveniences cause the customer to be dissatisfied with the replacement battery installed.

Start-stop systems – EFB versus AGM

 

Two different battery technologies are used for vehicles with a start-stop function. 

The decision about the battery technology used depends on what it will be used for. 

EFB Technology

 

EFB technology is mainly used in vehicles with simpler start-stop systems and generally with high energy requirements. 

 

If an EFB battery is installed in a vehicle, it must either be replaced with an EFB battery or, under certain circumstances, with a more powerful and cycle-resistant AGM battery. In identical housing and with a similar performance class.

PS: Minor deviations in capacity or performance during cold start have no effect on the safe start and the optimum power supply of the electrical system! Upgrading to the AGM battery makes sense if the vehicle is equipped with a large number of additional consumers.

EFB = Enhanced Flooded Battery, the cycle-resistant starter battery

Upgrading

Upgrading from an EFB battery to an even more powerful and cycle-resistant battery Running Bull AGM Battery may be in housing H5/L2 (60Ah), H6/L3 (70Ah) and H7/L4 (80Ah) under certain circumstances. When upgrading technology, it is essential that the new battery is configured in the system for start-stop vehicles with battery energy management systems (BEM)! The Banner Battery Service Tool (BBST) is perfect for this.

AGM Technology

 

This technology is primarily used for cars with start-stop systems with energy recovery and high energy requirements requirements. 

 

If an AGM battery is installed as standard in a vehicle, it must be replaced by an AGM battery. In identical housing and with a similar performance class.

PS: Minor deviations in capacity or performance during cold start have no effect on the safe start and the optimum power supply of the electrical system! 

AGM = Absorbent Glass Mat, the acid is absorbed in a glass mat, meaning that it cannot leak

 

x-change: AGM

Banner Tip:

Use the next largest battery for your car; there is usually enough space for this. Since these have additional power reserves for your vehicle! The difference in price is usually extremely small and your vehicle alternator is designed for it!
