got a genuine BMW battery ive been running on my golf vr6 for a few weeks to see if its a good one and it is, it doesnt look old at all! starts the car fine and holds charge!
one thing, you have the battery indicator - green for fully charged, black for saying it needs to be charged and clear meaning its no good / wont hold charge.
it sits on black but still holds a charge / works perfect and ive used a battery tester on it saying its perfect. anyone had these problems before? if you tilt the battery the green level indicator appears.
