Making a 4.5 Volt Battery Pack From a 9V Battery





Introduction: Making a 4.5 Volt Battery Pack From a 9V Battery

This instructable is all about splitting a 9V battery into 2 smaller 4.5V battery packs.

The main reason for doing this is
1. You want 4.5 volts
2. You want something physically smaller that a 9V battery

Step 1: Dismantle Your 9V Battery

This is your chance to be destructive. Peel back the casing of the 9V battery and you will find 6 AAAA (yes quadruple A) batteries. Each battery produces 1.5V.

Step 2: Separate 3 Batteries and Tape Them Up

Next you want to seperate a set of 3 batteries, ensuring that they stay connected to each other. Tape them up with electrical tape so they form a neat bundle.

Step 3: Add 2 Leads

Next, solder a piece of wire to each end of the battery chain. These will be the positive and negative battery terminals.

Step 4: Tape the Whole Thing Up

Nothing hard here. Tape the whole thing up into a secure bundle.

    will this cause heating issues?

    Can someone tell the details of this battery cells,i opened them and what i found were cells of carbon,can someone give me more information on that please


    hey, does this work with an eveready battery, because i opened it and what i see is the one on the left, and i dont know how to do this.


    You can buy AAAA batterys at radioshack

    they're probably ridiculously expensive though. I went there to get a three volt button cell and it was like, four dollars. I got a perfectly good package of five of them at the flea market some time later for a dollar.

    so, the million dollar question:  do these have to be new batteries?  can you do it with old batteries?  I just tried it, and it blew up trice in my face!  well, not exactly, more like -past- my face.  I was lucky (and smart) not to be looking down the 'barrels' of the battery!  the expiry date of the one that blew up on me was march 2003.  Perhaps I will try again with a brand-new battery?

    what's a lead, and where can i gat it?

    a lead is just a name for the (preferably thick) wire or pin connecting the battery to the rest of the circuit.

    The set of three, how is it arranged? Like: +++ + - + ? or ? - - - - + - ?
