My cars and bikes have the batteries in hard to reach places. This 10mm battery terminal rachet helps out!
In prepping the Vanagon Westy for a long roadtrip, I found I've killed my house battery. I ordered up a replacement but dreaded getting into the battery box. In a Vanagon, Volkswagen hides the batteries underneath the passenger and drivers seats. Getting at these battery terminals is a comedy of errors and blood. I'd go so far as to say the blood was compulsatory until I got this handy rachet at Harbor Freight.
It is small. It fits where I need it to. It is a rachet, and as such I am not constantly trying to re-seat the fucker while zapping myself against a grounded battery box in a thoughtlessly engineered tight space. At least the put a cover on the batteries, albiet a metal one. My '78 Audi 5000 with occasional self-determination had a passenger bench burnt with splashed battery acid from another VW/Audi underseat battery mistake.
