Went and got a charger today, was wondering which volt/amp setting was best to put it on.
The battery charger has 3 option settings ---> 6volt 6amp, 12volt 2amp, 12volt 6amp.

i left my marker lights on the other night and the car was dead in the morning. once i got it jumped to get to work and then home i set it up on a 6 amp charge for about 4 hours. battery seemed strong and everything was gravy. imma get into the routine to give the car a slow charge once a month.. I also dont drive very far.
My tender is "automatic" and cycles off once the battery is at optimal voltage. I've hardwired it to the underhood terminals and that way I only have to uncoil a long lead and connect it to the battery tender. The lead snakes out near the headlight area so I can leave the hood closed and the car locked in my driveway.

My Ride: 2004 525i, Metalic Gray, Premium Package
I need to replace my 2004 525i OEM battery. Negative terminal is easy to disconnect, but the positive terminal is beneath a few plastic parts and very rigid metal/cables. I don't seem to have access to the positive terminal itself. There is a nut securing the red cable above the positive terminal, but I think the positive terminal is 1 inch to its left.
Pls help.

Most, if not all, cars are 12V. 2amp is called either a slow charge, trickle charge or maintenance charge. Theoretically, the battery can stay hooked up forever.
6amp is faster and should NOT be left on indefinitely unless your charger is automatic that turns off once the battery is charged.
My charger has 2amp, 15amp and 100amp settings. 100amp is for a jump start or quick start.
Hope this helps.

I have a battery tender (the one sold by BMW (bought online without logo)) and connect to the battery as per the pic..
I close the hood switch with some wooden block (yellow arrow), so that I can lock the car and it would go to sleep..
