22. Coz those babies had ATOMIC batteries.

 

Or more correcty RTGs, able to provide a steady trickle of power over a period of decades.

A lithium batttery (any rechargable battery) can supply a relatively large amount of power in a short period of time, but then a current must be forced into the depleted battery to recharge it. Every discharge and recharge cycle irreversibly damages the battery. The deeper the dischage, the more damage is done. It's much like bending a piece of metal back and forth until it breaks.

Today even the RTGs aboard the earlier Pioneer probes are fading to the point where they can only provide enough current to run the radio transmitter and not much, if anything else. However, they have lasted as long as they've done, because their "discharge cycle" was one steady entropic decline.
