X5 Battery

[SPP]

Hi there

I was just wondering if somebody could give me some advice regarding the X5 battery, please? My workmate has been looking after his deceased father's X5 for a few months. He let the battery discharge! I recently took the battery out and trickle charged it at home. My charger said it was fully charged. Anyway, after putting the battery back in, nothing has happened. I can't get the car to start. The lights don't work. Nothing works except the hazard light does illuminate. I'm guessing the battery is no good, but as I said, it was supposedly fully charged. Perhaps there's something I'm not doing?

He just needs to get the car going as it's going to be sold. He'd rather not have to purchase a brand new battery. They're rather pricey, it seems.

Thanks

Paul

Do you have a code reader?

Try unplugging the IBS sensor on the negative battery terminal.

Can you start the car by jumping it from the hood posts?

Thanks, jbash87 for the advice and link. Will give it a go.
