Specification 125A Continuous at DC 12V 500A Momentary at DC 12V 15-17mm Battery Negative Column Top Post Knob Type Review: Super easy to fit. - 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!! Review: works fine keep dry or electrolytic action etches contact surface. - Cost effective. Does just what I wanted. Design fault on car flattened battery in 4 days when unused. I can now isolate battery for days and the car starts when I need it to. ## Features - Wide Use Battery Isolator Switch: Spurtar car battery isolator switch is suitable for most top post terminals (15-17mm cone battery negative post), which operates efficiently at 12V voltage and can handle a maximum load of 125A continuous & 500A momentary current, making isolator switch ideal for a wide range of applications - Safety Car Battery Terminals: This battery isolator switch is a device that allows users to quickly and easily disconnect the battery from the electrical system of a vehicle.

Its just a hole on that end!** A: Your original cable should have a "horseshoe" fitting that attaches to the post on the battery (if not I am not sure what you would have or if this would work). That horseshoe fits round the post end (not "horseshoe" end) of the disconnect switch. Hope that helps. **Q: Will this work for a 48 volt golf cart set up?** A: Note the product description says it is for 6-24V. Sometimes switches can be used outside the design spec, but when used at voltages above spec it is possible to get arcing, pitting, premature failure, or welding of the contacts. I would look for a within-spec solution. **Q: Would this work on a hybrid 2007 Saturn aura?** A: It will work anywhere there is a battery terminal. Look on YouTube. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Super easy to fit. *by A***R on 5 February 2024* Nice quality units. Very easy to fit, less than five minutes once bonnet is up!

Does just what I wanted. Design fault on car flattened battery in 4 days when unused. I can now isolate battery for days and the car starts when I need it to. ### ⭐⭐⭐⭐⭐ No more flat batteries *by S***S on 20 September 2024* After asking my local car electrics for a stereo or battery cut off switch and being refused I accidentally came across this on amazon while looking for quick release battery terminals. I bought a stereo which was draining my van battery every 5 days. Now with these i just turn the button off leave my van for weeks get into the van turn switch on and van starts up right away. This is an ideal product for anyone who’s vehicle battery is being drained due to some car electrical fault or electric add on which drains their car battery.
