Does any one collects old batteries? (plus other questions)

[Telecolor 3007]

Does any one here collects old batteries? I have 7 old pieces (4 x 1.5 Volt, 1 x 4.5 Volts, 2 x 22.5 Volts). I intended to get an at least 16 years old one from a recycling bin this night, but it had leaks on the bottom, so
I'm curios, when did you last seen for sale:
1) 45 and 90 Volts batteries;
2) 15 and 22.5 Volts batteries;
3) 1.35 Volts Mercury batteries.
