2pcs Top Post Battery Master Disconnect Switch Battery Isolator Switch

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!!

Fitted on a Renault Convertible. It is working great!

A good switch mechanism which isolates my main camper van battery when it is in storage. However it was quite a fiddle to fit because of it's length in the tight battery compartment and with the arrangement of the terminals. Check this before ordering.

Fantastic product

Perfect does exactly what it should! Was bought to replace a remote controlled isolator which only lasted a couple of months before failing !

Does what it says on the tin

It's a switch, it should be simple. Using a meter measuring resistance, the switch appeared to be open or closed correctly. Once fitted to the car, switched on, it passed 12+ volts, no trouble. However, in the off position, it was still leaking 2.6 volts, so not exactly isolated. The metal seems quite soft. Although stamped with CE markings, it appears to be the usual far east manufacture. I would not recommend. I have not got the time or inclination to raise the issue with the supplier.

I have been fitting these to various cars, and they are great quality. Simple to fit over the negative terminal, and they can then be used to disconnect the battery by turning the top wheel. Perfect for any car which isn’t used regularly, and of course you don’t need to remember your spanners when going to the lock up! I’ve also found that old battery clamps get damaged and are difficult to take on & off - with these you only need to attach the clamp once & don’t need to ever take it off again. I smear everything with Vaseline when fitting, and have found no issues with these isolators at all - some on the market are cheap and flimsy, but these are nice and sturdy. Highly recommended.

Sono spesso fuori per lavoro e, a seconda dei posti in cui mi sposto, a volte sono costretto a lasciare l'auto. Lo staccabatteria mi ha permesso di evitare di perdere altre batterie in maniera semplice e veloce. Si collega facilmente alla batteria e velocemente si stacca e riattacca.

Works the way it should. Saves my truck battery from draining. The posts are strong and holding up fine.

Perfekt produkt, passade fint till standard batterikabelsko

Zoals beschreven prima product

Makkelijk te installeren en prima oplossing voor lekspanning. Als de auto een paar dagen niet gebruikt kan je de accu simpel ontkoppelen, nooit meer een lege accu.
