Power switch for car battery.

[This review was collected as part of a promotion.] For my installation, I had to reverse the poles because my battery cable wasn't long enough.  But, it was very easy to take it apart and switch everything 180 degrees.  I LOVE IT!!  No more disconnecting cables every night to avoid the parasitic drain that happens without disconnecting.  This lever makes it so much easier!!

Wish I'd found it 2 years' ago!!

[This review was collected as part of a promotion.] Works well on my old tractor that would discharge the battery. I would always unhook the negative lead but this is a lot easier. I worried about starting current but it handles it no problem.

[This review was collected as part of a promotion.] Good product, good value.  Saved my battery from a possible short in an old tractor.

Good product

[This review was collected as part of a promotion.] Exactly what I needed for a good price!

[This review was collected as part of a promotion.] Great quality

Works perfectly

[This review was collected as part of a promotion.] the threads on the battery cable side do not fit the battery cable, different size on the side post cable

not made for american autos

It does not fit on group size 75 or 78 batteries!
It does not appear to fit on any standard American car battery

Useless product
