Safe and Effective
A wrench out of your tool box will work just fine to remove the cables from your battery side terminals. However, these tools offer a couple of few benefits that are worth a look.
To begin with, they are insulated. Metal tools accidentally shorting a battery terminal out are a potential disaster. What started as a casual afternoon project or task, can easily become a horrible mess.
The second is that they are ratcheting wrenches. This not only reduces the need to remove and clock the wrench before taking another turn, but the tool has a lower profile than sockets and drives. This low profile is very desirable when clearances are tight.
There are two common sizes for these wrenches.
One measures 5/16 ” and is typically found on batteries in GM cars.
The other is 10mm and is found on imports and some domestic vehicles.
The best thing to do before buying one is to size your current terminal.
The handle length is about 5 1/2 inches. This may be ideal in tight quarters, but may require a little extra effort to bust a tough terminal loose.
This will cost you about eight bucks. You can buy one HERE.
