A. Introduction:

  This FAQ is used to explain what happens when you're game can't save
anymore, or it doesn't save too well anymore.  The reason for this is the
lithium battery inside your SNES cartridge has died out.  In this FAQ I will
explain how you can get your battery replaced, and the many methods to doing
it.  So if you want your old game to save like brand new, then continue to
read on.

B. Replacement FAQ:

  Ok, here is the part you have all been waiting for, the replacement guide.
Here I will tell you the many ways to replace your battery, and what exactly
causes your battery to wear out, and also the materials needed.

  1. What you need:
     Before you decide what you need, you need to decide what method you want
   to use to replace your battery.  There are two commonly known methods people
   use.  Soldering and electric tape.  These are things you need no matter what
   method you plan to use:
     -3.8mm Security Screwbit($3 at or eBay)
     -New CR2032 battery($3 at Radioshack)
   a.  Soldering:
       If you want to solder then you need the things listed above as well as
       some other things listed:

     -Soldering iron, and some solder($10 at Radioshack)
     -Wire(At Radioshack)
     -Battery Holder($1 at

   b.  Electric Tape:
       For electric tape you only need the two things listed at the top as well
       as some:

     -Electric tape(duh!)

  2. What causes batteries to die:
     Very simple actually.  The reason a battery dies is just like any
   battery.  It wears out over age, and you need to buy a replacement.  The
   only problem is, SNES batteries are a little harder to replace, and that
   is what this FAQ is for.

  3. Removing the old battery:
     This isn't that hard.  To start, get a flathead screwdriver or a thin 
   knife, or whatever is thin and sturdy.  Now you will need a 3.8MM
   Gamebit to open the cartridge up.  Take off the 2 screws and remove the cover
   and you will notice the backside of the chipboard.  Turn it over, but to
   not damage the chipboard, ONLY hold it by it's edges(like you would a CD).
   Flip it over, and you will see the CR2032 Lithium battery.  Now what you
   need to do, is take the knife, flathead screwdriver, or other flat object,
   start to pry at the Solder points.  Keep wiggling and slowly pushing it
   further on the top tab.  After enough wiggling and pushing it should come
   loose.  Make sure you take it slowly, cause you don't want to break the
   top tab, doing so would make it totally broken, and you won't be able to
   save anymore.  Do so for the bottom tab too.  After that you are done, you
   can start on the replacing.  Read on...

  4. Methods to replace dead batteries:
     Let's replace this battery!  I will list
   both ways of replacement, you pick what you want(Soldering or Electric
   tape).  Read on:

   a. Soldering:
      This is the method Nintendo used to add the batteries, and is the most
    reliable.  It is also the most hardest and tedious way as well.  To start,
    heat up your Soldering iron, and wait about 2 minutes or so.  Now connect
    a few inches of wire from the bottom tab and connect it to the negative
    side of the battery holder.  Now take some solder and the soldering iron
    to solder the wire onto the bottom tab and the end of the wire to
    the negative side of the battey holder.  Do the same thing with the top
    tab to the positive side of the battery holder.  Once you are done with
    that, pop the battery into the battery holder.  Then you can take some
    tape(electric tape, anyone?) and turn the tape into a two sided piece
    and stick to the wall fo the cartridge, and stick the battery holder to
    it.  This is to prevent the battery from rattling around in the

   b. Electric Tape:
      This method is a lot easier then soldering.  However it is not as reliable
    and the tape wears out after a while.  If you want to use this method,
    however, just hold the new battery and the bottom and top battery tabs
    all together, and wrap a piece of electric tape around it.  Use another
    piece for more reliability.  Then take some pieces, and start taping it
    all over the battery.  Keep doing this until you the battery can't move
    anymore.  In the end it may take about 7 or 8 pieces of tape.  This method
    gives satisfying results, but the tape sometimes randomly lets go and causes
    your save files to erase from time to time.

   c. Professional help:
      Are you having problems with either of the methods?  If so, you can
    contact Nintendo themselves and send the cartridge with the bad battery in
    it, and they will professionally solder a new one in there.  However, it's
    not free.  I have seen them charge from around $15 - $20 for the job.  Not
    including shipping costs!  So use this option only if you just absolutely
    give up on the above methods.
