I've seen a couple of these Minidisc portables for sale on CAM in the last year or so, and one of the issues with them is that the batteries are no longer available. The battery in the RH1 is a 3.7v LIP-4WM, and unless you want to pay $100+ for a 10+ year old battery on ebay that's likely not going to work, this seems to be the only solution.

I ordered up a couple of these generic batteries:

and followed this guide to hack together a new battery:

The battery pack fits quite snugly in it's compartment due to the slightly fatter replacement battery, but can be pulled out ok with the tape flap. The MD charges the battery with no problems and plays without issue. The original gumstick battery is 370mAh, and the replacement is 350mAh, so a slightly reduced playback time.

These generic batteries are easy to find in a variety of voltages, physical sizes and capacities so if you have a similar battery problem you probably will be able to find something that will work for your device.
