I'm going to do this mod on my Zookeeper and I've been wondering about this for a long time. How is a cordless battery supposed to get charged and thus save settings & high scores? I don't have a cordless phone so that isn't an option. Am I out of luckl?
 
The board will charge it. Just make sure to turn the machine on here and there to ensure it charges some.
 
I've had this mod on my Omega Race for 12+ years, same battery, no issues. It gets turned on once every few months, though it once went 8 months in storage.
 
Games that have batteries on them usually use rechargable batteries, often nicads, usually 3.6v, and usually somewhere around 150 milli-amp hours. A A cordless phone battery is usually 3.6v, nicad, and about 3000 milli-amp hours. Which means it's basically the same thing, just in a higher capacity. So it charges in exactly the same way the original battery did, with no modifications.

I personally did this to a couple of games, but later switched to a diode with a lithium coin cell, because the remoted battery was a pain for getting the boards out. That's just a matter of preference, though - different folks like different things.
