Sorry about that, it has been called a sled before on the list. Oddly
enough I usually call it a tray as well. Figures the one time I use the
term it would cause confusion. It is also sometimes called a battery

You can modify the battery tray to allow for charging of normal NiMh
batteries. However it is not easy and you need to have a temperature
sensor installed (thermisistor also called a poly switch). There are
detailed instructions somewhere but I am not finding it at the moment.
But perhaps one of the other listers has the link handy. I have never
done it as it doesn't take but a second to change the batteries. And if
you have 2 trays even less time. Just pop out one and slide in the
other. ;) Also I don't like the idea of taking a chance on frying my
2000 due to a charging malfunction. Probably less likely, but with the
ease in changing them out, I don't see it as a reason. I just wish I
could get such a tray for my emate.

I also found a battery tray at J&K sales for 34.99.
