This seemed to work fine but my battery light came on so I removed it. The battery light has not showed up since.

Although of apparent decent quality it stuck up too high, which would not allow for the hood to close properly.

A straightforward installation, precisely what I required. This device enables me to deactivate the battery, ensuring its longevity over an extended period. This is an excellent alternative to the battery maintainer, as I lack an outlet nearby. If you aren’t concerned about the radio codes being erased when the battery is switched off, this will suffice. The installation and usage appear to be of high quality. To enhance protection, I have added corrosion-proof donuts to the terminals.

The DMTVAL Top Post Battery Disconnect Switch is a game-changer for my car. It’s super easy to install and makes cutting off the power quick and hassle-free. The build quality is solid, and it works exactly as advertised. Perfect for preventing battery drain when my car is not in use. Highly recommend it for anyone looking for a reliable power cut-off switch.

Good concept, but the design is obviously not up to American (as I think) standards. Engineering is off a few and extra tight to place over a true American battery post. You’ll need to separate the lug and hope it doesn’t Crack apart tightening up.
