5.0 out of 5 stars Problem solved! No more dead battery 🤨
By Jane W. ~ W. on May 29, 2022
My 2016 Toyota Tacoma’s battery would go dead constantly, if I didn’t take it out for a drive often. To many gadgets that drain the battery. I even got a new battery for free under warranty.
This cutoff has solved the problem. It’s a pain in the butt to have to open the darn heavy hood but a lot faster then using a battery pac or dragging the cord and charger out just to go somewhere and then still having to lift the heavy hood. Arrrrg!!
If I know it’ll be awhile before I go somewhere I just flip the switch to stop the drain. It seems that Toyota could install an in cab cutoff to make life easier, it would be especially nice to have in winter when my hill is icy and I worry about ending up under the pickup. The dealership still hasn’t figured out the why…well the cutoff ends that problem. 🥳🎉
