Battery Life

What ever batteries you buy they are all miles behind in terms of technology.

You would think they would have sorted something by now with the future looking to depend on the technology. The tech that is around is all integral with computer programming constantly ensuring the health of the cells. Basically a computer controlled battery, which is how they try to make a small battery like the one in your phone healthy but unfortunately what ever you do the cells degrade.

Wonder how a car cycles a battery, probably why they dont last long.

That’s impressive but I’d seriously consider replacing it for a new one before it bites you in the arse :cry:

It seems that the old lead acid type last, while the new fangled AGM types with fancy charging controls - dont !

So I bought a 35is with all the toys to play with. :thumbsup:

If it leaves you stranded somewhere, only happens at the most inconvenient time possible-I think bmw fit a sensor to detect such moments & then kill the car :lol:

Excuse my ignorance, but why would a battery need programming?

...On the flip side - the old fashioned lead acid battery fitted to my first Z4 (2004 E85) and sold to a pal, is still going strong !

Progress eh? :rofl:
Amazing but the battery in my June 2003 e85 is the original date stamped BMW unit! I always stick it on the Ctek when it's not used for a week or more but I can't imagine it can last much longer, there again who knows?

What is battery programming anyway?
Would you mind pointing out where the date stamp is I'm blowed if I can find it on the one I have just taken off mine. :thumbsup:

Production manufacturing of all kinds often date mark products using year & week number rather than a date, there is the code 03/25 stamped on the neg - terminal (which is 2003 week 25 = June when my car was built). The etched serial number starts 0306 as well which tally's with the year week code.

Your thread encouraged me to test my battery yesterday, under starting load the volts were dropping to below 10 when starting despite using a ctek battery conditioner.

One Bosch S5 agm battery later she starts up quicker than ever and on starting the volts went down to only 11. Ten years out of the original battery seems fair :D
