    You missed several important steps. First you should use a small battery (l have one attached to a cigarette lighter plug) to keep the memory in the radio and computer from being erased. Second you should have a terminal puller tool to get the cables off. Third you should use a battery cable reamer to get the holes in the cables round and make good contact with the new battery. Fourth you should use a cable clamp spreader to open the terminals so that they can seat all the way down on the new posts. I have installed hundreds of batteries over the last 50 years and these steps will save a lot of grief.

    Is it okay to replace the battery when the engine is running?

    Step one is to connect a keep alive battery to maintain your cars' computer memories. If you dont do this, you could be looking at a car that barely runs or doesn't run at all, and a tow to a dealershiup in some cases to do the reprogramming.

  • Instead of the felt and that spray which won’t last, put some dielectric grease on the terminals and clamps.

    If you disconnect your battery without using a computer memory savor in most modern cars you will lose all the computer saved pre-sets and you may have a lot of electrical and engine problems. You better do some research on your particular car or you may get a nasty surprise.

    At 1:00 you say not to bridge positive to the chassis with tools, however with the negative terminal removed that shouldn't happen? Isn't that the whole point of disconnect negative first and connect it last so welding can't happen?

    Newer cars may have issues when changing the battery due to the fact that they have eay more electronic stuff.

    Don't you need to have a portable battery hookup up so the car doesn't lose memory of radio presets?

    I heard if you leave the wrench across the battery terminals it helps reset all your monitors

    Missed a vital step. Before removing the failing battery, use a memory saver. If you don't you'll lose all settings and might have other electrical or performance issues.

    Also, take off the month and year stickers off of the battery, so you remember when you installed it.
