Summit calculator

I have a Summit calculator purchased around 1975? I love the keypad and everything else about it, but it doesn't work anymore. I suspect the rechargable batteries are shot. I have the charger but it won't take a charge, and has no display no matter how long I leave it on charge, and I can't even figure out how to get the case open. Can anyone help?
