TYRE CHANGE TIME = BATTERY CHARGING TIME
PRO TIPS NOT ONLY FOR SPRING AND LATE AUTUMN
Charge your car battery correctly - simple tips for MEGA starting power and a long service life!
It is best to always combine external recharging with a tyre change.
Not only short journeys are a real challenge for the battery, but also stop-and-go traffic, poorer charge absorption with a battery that has been in use for longer, especially in winter, a lot of additional electrical consumers and many journeys in economy mode. Now your car often needs more energy than the alternator can produce and recharge in the battery.
In start-stop cars, please note!
If recuperation is also used in the start-stop vehicle (recovery of braking energy), the AGM or EFB battery artificially operates at a lower state of charge of approx. 70% (SOC State Of Charge 70%). This is because charging capacity must remain free in order to be able to charge the regenerated braking energy into the battery. The AGM battery therefore works in partial charging mode and 100% full charging of the battery can be achieved through recuperation.
In older cars without a start-stop function, the battery was always fully charged by the alternator.
A charging deficit can occur relatively quickly in the start-stop function and lead to partial or full discharge, even with an almost new battery. Even a jump start is only useful for a short time if the battery is not immediately recharged using a charger. An external periodic 100% full charge is really optimal!
Please bear in mind: Especially in winter operation, below 0 degrees Celsius ambient temperature, the battery hardly draws any more charging current - regardless of whether it is used for short or long distances on the motorway. At the same time, many power consumers are in operation, such as the rear window heater, seat heater, parking heater and a few others! We are now completely ignoring the Economy (ECO) driving mode, which sometimes reduces the charging voltage to approx. 12.3V! SORRY, the battery is no longer charged while driving! Starting problems or, in the worst case, total battery failure are then practically pre-programmed!
Banner tip! Periodic external charging using a charger is a real fitness programme for every battery - whether starter-, on-board power supply- or long-term discharge battery!
PS: If this work with the DIY do-it-yourself battery charger seems too complicated for you, then your trusted workshop will certainly do it, sometimes as a pure service, without exception at every workshop visit.
One more thing: Strictly speaking, a tyre change is almost always a wheel change, but the ‘average Joe’ usually uses the term ‘tyre change’.
