Battery tip: Application and function of the battery sensor.
What is the function of the sensor at the negative terminal of the starter battery?
The electronic battery sensor is an important part of energy management in motor vehicles. The sensor gives the car precise information about the battery status and controls the charging voltage and charging current accordingly.

The massively increased on-board currents in modern vehicle models and in particular the microhybrid applications start/stop and recuperation (=recovery) of braking energy place new demands on car batteries. More and more often, kinetic energy is also converted into electrical energy during coasting (=free rolling of the car), thus charging the battery.

 

Application and function of the sensor. Energy management continuously records parameters such as voltage, current and temperature via the battery sensor. These measured values are used to calculate important parameters such as charge status, functional status, overall battery status and a large number of other values.

 

The data is transmitted to the vehicle computer. The computer then decides on the energy balance in the vehicle and, if necessary, restricts the use of comfort consumers such as seat heating or air conditioning, deactivates the start/stop function and signals this to the driver on the display with corresponding instructions. If the alternator then recharges sufficiently, the control unit automatically reactivates all consumers and functions.

 

The customer benefit briefly noted. The primary aim is to ensure that the engine always starts and thus avoid vehicle failure. In addition, the sensor supports intelligent alternator control, which reduces CO2 emissions, saves fuel and protects the environment. If the battery no longer delivers the desired performance, "defective battery" is stored in the system and this early warning makes it possible to plan battery replacement.

Battery tip: Get your car battery ready for spring!
Spring is the perfect time to check the battery and recharge it.
Give the battery an extra portion of external recharging after winter.

Frequent short journeys, irregular driving profiles in combination with stop-and-go traffic, daily cold starts in icy temperatures in winter as well as additional electrical consumers such as seat, stand or rear window heating have lowered the energy level of your battery start for start and drive for drive. At the latest when changing tyres in spring, you should allow your battery an extra portion of external recharging!

 

Charging the car battery

Battery chargers for professional battery charging and conservation. The devices ensure a safe start, optimum on-board power supply and extend the service life of each battery (standard, AGM, EFB, start/stop and GEL batteries). Simple, fully automatic, safe and fast.

 

Voltage testing

With a voltmeter you can measure the battery voltage quickly and reliably. A voltage table on the device provides information about the charge status of the battery. Very simple application with high accuracy!

 

You can find more tips about the Duracell battery under the menu item Infocenter

We wish you a beautiful spring and a safe drive!

Battery tip: Giving a jump start.
You can always rely on a well-maintained Duracell battery, but what happens when a neighbour has starting problems? You naturally want to help and provide quick and simple assistance. That´s how you do it right!

However, one thing should be noted from the outset. Namely, that in view of the sensitive electronic components in the vehicle, as a rule starting assistance should only be given by means of a Booster. This is because start assistance from vehicle to vehicle can lead to voltage peaks during the disconnection of the terminals, which can damage or even destroy car 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 when giving starting assistance.
– Observe the instructions for the use of the starter cables.
– Only connect batteries with the same nominal voltage.
– When connecting the terminals, switch off both vehicle engines!
– 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 requiring 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.

 

Attention: The car battery is not always installed in the engine compartment, but can also be located in the interior/passenger compartment or luggage compartment. The procedure of the jump start remains unchanged!

 

Get through the winter safely and well!

Battery tip: charge car battery correctly!
So geht's richtig!
Now is the perfect time to recharge the battery. That's how it works!

Charging of conventional wet batteries and EFB batteries:

 

- Before charging, check electrolyte level and, if necessary, fill up desalinated or distilled water to the max. acid residue mark or 15 mm above the upper edge of the plate. The screw connections of the battery must not remain open during charging, it is best to close them again.

AGM batteries must not be opened, refilling with water is not possible or necessary.

 

- Connect the positive pole of the battery to the positive pole of the charger and the negative pole to the negative pole of the charger. Only switch on the charger after connecting the battery. Switch off the charger when charging is complete.


- A tenth of the capacity is recommended as charging current. (e.g. 44 Ah: 10 = 4.4 A charging current). With an automatic charger (e.g. Banner Accucharger) this setting happens, as the name suggests, automatically.


- Charging is complete when the current drops to 0 or no longer decreases or the automatic charger switches off. Provide good ventilation during charging. Attention: Highly explosive oxyhydrogen gas forms during charging! Fire, sparks, open light and smoking prohibited!

 

- AGM batteries must be charged with a voltage regulated charger, e.g. Banner Accucharger (max. 14.8V)!


As a general rule, fully automatic chargers (charging voltage limitation with 14.8V) are well suited for charging the battery installed in the vehicle. If your charger has an automatic mode with voltages >15.9V, the battery must be disconnected from the on-board electronics or removed from the vehicle. In the worst case the installed control units could be destroyed by overvoltages, the resulting damage would be enormous!
