How To Hack A 12 Volt Battery

You will be surprised what's inside a 12 volt battery! An easy hack that will save you money! You will be surprised what's inside a 12 volt battery! An easy hack that will save you money!

Step 1: 12-Volt Battery

In my other battery hack video, I showed you how a 9-volt battery could save the day. Well, it's time for another cool trick, this time with a small 12-volt battery.

Step 2: Cost

This is one of the easiest hacks to do, and it'll save you about $40. I picked up two A23 12-volt batteries for less than $2.

After splitting the case with a screwdriver and peeling it back, what you'll find inside are eight 1.5-volt button cell batteries.

I found the matching battery for $4.99 at an electronics store. I was able to power up these 6 devices with the batteries I hacked from the 12-volt battery! And I saved about $40! Cheap and easy with a big payoff: the 12-volt battery hack.

    I think Girlygeek is an idiot. Step one get the right battery. If you use the wrong one, then yeah its going to leak battery acid every where. Step two..... don't puncture the battery. Even if you try this on the wrong battery as long as you aren't applying pressure or trying to saw the thing in half the worse you could get is some battery acid leaking onto the surface that you are working on. If you use the A23 photo battery this will work. Don't try any others unless you want to take the risk.

    They are available in the US all day long. We sell them at Autozone all the time. Many car remote fobs take this battery.

    Danger!!!!!!!!!!! This is a spoof. i think maybe this entire site is. i tried this one and got battery acid splattered onto my face and almost in my eye. There is cadmium in battery acid, led and corrosive chemicals. Imagine if a child tries this and goes blind! Who would be that F-cked up to do such a thing and even go through the trouble of not only faking a battery, but video taping it to boot. This is criminal and who ever posted this should be reported to the authorities!
