Just for clarification, I said nothing about charging the battery with the alternator. What I posted is there is no correlation between the life cycle of a battery and that of an alternator.

The only reason this was ever done back in the 60's & 70's is people did not own a multimeter and it was a backs woods way to test for charging.

Why this is even discussed or considered in 2015 when you can buy a multimeter for the price a a few cups of Starbucks and possibly risk damaging or even glitching a module is not even worth the discussion.

Especially when many of the BMW models have a built in Voltmeter and you do not even have to buy anything, open the hood or get out of the drivers seat.

A Voltmeter is really all that is required to get a very good idea as to what is going on with any battery or charging system. Yes, having more than a Voltmeter or tools that can verify AC ripple, measure Amerage and apply a load is all fine and good, but if the charging system or battery can meet some basic Voltage measurements, it is pretty much the case that things are working correctly and in good shape.

So anyone that wants to disconnect their battery cable, go ahead, I believe the more knowledgeable crowd would recommend that this not be done.

No one has posted they think it a good idea to remove the battery cables and run the engine on the alternator. No one has said the voltmeter is not the best way to check the electrical system. FYI, I liked the phrasing of your initial posts much better than your most recent ones.

Battery out of car tested at terminals was getting a read of 10-11 volts.

Throwing on trickle charger.
Date on battery says Aug 09 ! Haha

Now Im hoping my alternator didn't get killed trying to drive half way home yesterday.

If battery charges enough to start car I will do a running test.
Can i test at the front jump location while running ? Or does it have to be terminals

Or if someone would explain the obc. The online directions are misleading bcz I only have one knob no right knob...
And when I get to the test number for battery volt it goes back to main temp and info

If its that old I'd just get a new battery

:iagree:

Did you go agm battery? And would I be fine getting an autozone or napa auto battery?

Anything is better than the old and mostly dead one you have now. I got the Bosch AGM from Pep Boys since I had a coupon code and a mail-in rebate, you'd be fine with Autozone or Napa, just get the most cold cranking amps you can get.

Current one I just took out was bosch. I'dk where I could get one locally. There is no pep boys around me.

I don't have a pep boys near me so I bought an Orileys battery, had more CCAs than Napa or Autozone. Just get the most powerful one that is local and you'll be OK.
