Where is the battery located in a BMW 730?
2 Answers
The battery of the BMW 730 is located at the bottom of the rear trunk. Here are detailed information about the BMW 730: 1. Model-related: The BMW 730 is a high-end luxury car produced by the German automaker BMW. It belongs to the BMW 7 Series and is exclusively manufactured in Germany, replacing the previous model, the BMW6, in 1977. The BMW 730 is the first large luxury four-door sedan produced by BMW, equipped with an inline six-cylinder engine. 2. Precautions: Reduce electrical usage when the car is turned off. Additionally, to prevent moisture damage, the car should be used regularly, and the battery should be replaced periodically.
Every time I help friends with the BMW 730's battery issue, I first open the trunk and locate the rear right corner. There's either a carpet or a hidden compartment cover that needs to be lifted—the battery is concealed underneath. This design primarily aims to balance the vehicle's weight distribution and avoid the heat from the engine bay, ensuring smoother driving. If you're replacing it yourself, remember to empty the trunk first, then use a wrench or tool to loosen the compartment bolts—some models have dedicated slots, making it quite straightforward. Most importantly, always disconnect the negative terminal first; otherwise, accidentally touching the positive terminal could cause a short circuit, triggering system warning lights. Additionally, the BMW 730Li generally follows this layout. Common signs of battery aging include slow starts or weaker horn sounds. It's advisable to check the terminals for corrosion quarterly and clean them with a damp cloth to extend lifespan. If you can't locate it, avoid forcing it open—there might be a locking mechanism under the carpet. Beginners should consider recording a video and posting it in social media groups for help—it's safer and educational. I've seen many share such practical tips, which are really handy.
