Deal Details
Tired of getting back from vacation, only to find your car battery dead in the airport parking lot?

Tired of your teenage kids **borrowing** your car while you are at work?

Got that classic car that you drive on weekends, but don't want stolen from your driveway?

Modern cars and boats have tons of gadgets that constantly drain your battery while parked, and a battery disconnect will keep you at full charge.

You don't have to hook up the voltage display, unless you like the bling.

You can disguise the entire thing with a quick wrap of Gafter's Tape, then cut under the knob to allow it to turn.

If you do a good job concealing it, even someone with jumper cables won't be able to steal your ride.

Remember to click the "Coupon Price $23.99" box, under the full $30 price:

Oh, I thought it will automatically cut battery off if voltage goes below certain threshold. But it does not do that. Well, then I will just disconnect the negative terminal if I have to manually cutoff battery anyway. Not really that useful.

Your teenage daughter will instantly see a disconnected battery terminal.

This offers a tool-free way to disconnect the battery, in an easy to hide package.

That'll stop someone from starting the car but it wont stop your battery from draining if its just sitting not being used for long periods of time.
