Possibly correct (I really don't know) but any charging system worthy of the name would quickly discover that the battery is fully charged and adjust or it would risk massively overcharging any battery and possibly boiling it. There is no magic here, the charge state of a healthy battery is directly linked to it's terminal voltage when charging or when discharging (values are slightly different for AGM vs. wet cell batteries). Crikey even the old fashioned dynamo chargers with no electronics at all would charge a battery until it is full and then stop.on some cars a new battery has to be registered with the ecu so it can be charged correctly, effectively clearing the memory of all info concerning the old battery so the characteristics of the new battery can be learnt and charged correctly. on some makes of car if you do not register the battery certain functions will not work. kia's system is a self learn and will charge a new battery correctly. (it will know a new battery has been fitted) any data lost in the ecu (on a battery disconnect) will also be relearnt
Just to be clear, can you confirm that you effected the change without any assistance from a memory-saver?Swapped the battery over with no problems
+1..and also did you or hellfrauds fit it you did not say.. just that it was £150 and halfords..Just to be clear, can you confirm that you effected the change without any assistance from a memory-saver?
I have swapped out rather a lot of batteries including the modern gel types and I haven’t broken anything yet. The only nuisance I have experienced is loss of the radio code on a few cars but that’s easily remedied providing it was noted for just such contingencies.
Yes you can do it that way but this is a far safer way to do it..The last battery change I had, the Mechanic connected a 12v motorcycle battery across the terminals before he undid and took out the failed battery. Put in and connected up the new one and then disconnected the motorcycle battery. There was no disruption of power to all circuits.
Hi, can you please advise what battery name / model was please from Halfords. I went to Kwik Fit today and they said that my current battery was 640AH and they ones they had were AGM115 800AH, an were relucant to replace it becasue of the difference in AH.Swapped the battery over with no problems , ....now have the stop start working again as well !......£150 from Halfords for AGM battery
