Hi Frances,
I'm almost sure that there's also a kind of protection into the AAA batterybox,
similar to the one found in the motors to protect it for short cirquit/overload
causing injuries.
It's defenately into the rechargeble battery box.
I guess that it protects until a max. current draw of 800mA.
If this protection divice is a bad component (got this into a 9V train motor)
then the protection will activate way too early causing the motor to stop even
it's not the way it should be.
If you can figure out that it's the battery box, i'll recommand you to contact
customer service for a replacement.
Perhaps you tell them your probem. Then Customer service can deside if you need
to ship the bad battery box to them to find out what's going wrong.
Just my toughts.
Regards,
Ludo
