Have bmw 735i want to sell, but where is the battery to charge it up.1991 or 93 i think?

On a '91 525i series it's under the back seat, pretty sure the 700 series is too. Pull upwards at the front edge of the rear seat lower cushion. Takes a bit of effort but it should pop on up.

The battery is under the back seat, on the passenger side. But you don't need to get to it to charge it. If you look under the hood there should be a little black plastic box with a a big plus sing on the top, inside you will find a connection for the positive cable of your charger, and you can place the negative on one of the bolts on the top of the shock tower or any other part of the body that is not painted.

Back seat. I think there are little red tabs you press, at the bottom of the seat where it meets the floor. There are battery chargers that work through the cigarette lighter.
