Spurtar Top Post Battery Isolator Switch 12V - 24V Kill Switch Battery Disconnect Terminal for Car Truck RV Boat Vehicles, Green Knob

Nice quality units. Very easy to fit, less than five minutes once bonnet is up! Works well, switches on and off easily. Arcs a little when switched on as expected so with prolonged use may need cleaning on contact surfaces. Don’t over-tighten battery terminals or it may snap or damage when fitting. Keep it clean so no electrical tracking can take place which would cause slow discharge of battery. Make sure that there is room for it to fit next to the battery. Only fits on the negative terminal, makes it a little safer for DIY fitters when using a spanner near the battery, -presuming negative ground vehicles! Should increase life of battery as a good battery will only need a top-up charge occasionally. Definitely slows discharge times.Wish I had found these years ago instead of taking the terminal off every time!!

Easy to fit, good value, amd saves me having to try and hunt down a parasitic drain!

Works as expected, sticks out a bit far and was a squeeze to fit on my Zafira but can be done.Does the job of isolating the battery and reasonable price.

Well made easy to use and unstable. Excellent quality perfect for standing cars for long periods of time. Easy to reconest power

Used to isolate the battery if the car is not to be used. Works very well

For my car left for months at a time in France.Easy to fit and operate, but you must be able to manually open your bonnet.So far the car has started first time and I am happy wth the produc.

I've a VW Passat with the battery fitted in a plastic battery box in the Engine Bay.CONS:1) The original negative battery lead will not reach the new terminal post on the isolator.2) The battery enclosure would need to be cut and modified in order to fit the isolator.3) Be careful not to over tighten to the 'Closed/ON' position. The knob is difficult to grip if too tight due it's proximity to the post.PROS:Isolator works fine and is pretty solid.

I use one of these on my car to disconnect the battery simply, the car stands for several days and due to its age it has battery seepage. This is an easy remedy, I bought one for my son in law, he has had a similar problem. Ideal.
