Frankie, do you remember me?
Do you remember songs from the 1980s by Sister Sledge? I know I do. Does you Mega STe not even remember the
time and date? No? Well mine does. 30 year old batteries have a habit of not working, as shocking as that may sound,
fear ye not, a simple fix is available that almost anyone can do. Including me.
What you will need:
1 x Ajax Scientific Battery Holder ideally already wired.
1 x ACT ER14505 AA size 3.6 2700mAH Lithium Battery
2 x 2.54 Dupont Connectors (Female)
2 x 2.54 Dupont Housing (Single)
1 x pair of long nose pliers.
How hard can this be, you cry? Not at all I say.
Step 1. Strip. (Some shielding off)
Strip a bit of shielding from the wires coming from the battery holder. Chances are it’s already been done. You
only need a couple of millimetres from each.
Step 2. Attach a dupont connector to each wire.
The Dupont connector has to two sets of grips. One set
to hold the wires plastic shielding, another set to hold the
actual wire. Crimp the first set around the shielding
using your pliers as seen in the picture (Left)
Now crimp the second set around the actual wire. You
can get crimping tools to do this, but in my experience
the cheap crimpers are horrible and  your better
just using pliers. if you intend to make thousands of
cables like this, then a crimping tool maybe a good
investment. Just don’t buy a cheap one from eBay.
Step 3. Slide on the Dupont housing.
Slide on the housing to both wires and you’re golden.
Step 4. Insert the battery into the battery holder.
Negative on the springy bit, positive to the non-springy bit
in the holder. (See Left)
Connecting the Battery to your Atari Mega STe.
Your looking for Jumpers J401. If the Mega STe’s
motherboard is facing you, they’re in the Top Right side,
near the edge, just below the floppy connector and to
the right of your SCSI adapter board if you have one.
The Positive Connector (Red wire for me) goes on the
first pin, the second pin is left and the third pin down
takes the negative. (The black wire for me)
The battery can be popped in the space where the original
battery was, at the back of the case, just north of the
floppy connector.
That’s it, your done.

My Private Computer Nostalgia
The late 1980s and early 1990s were my personal golden age of gaming. I like tinkering with them, I like seeing what they can do and I like making a website. So here we are.
