MODERATORS
Rechargeable batteries weren't really a thing in the 70's. For consumer electrical devices, batteries were one use, and anything that plugged in needed to stay plugged in while in operation.
Big advances in battery chemistry made things like cordless phones feasible by the 80's, and all sorts of rechargeable devices in the 90's.
Early cordless phones would still destroy batteries with garbage battery management system well into the 2000s.
And they had those fucking stupid 2pin molex connectors that, despite being 4 mm across, had literally 2747329 different keying combinations for different vendors.
