[NTLK] The death of a MessagePad 2000 battery

Two reasons IIRC,

the recharge circuit in the Newt reads the temp on the batt., so a lower temp allows the circuit to recharge a batt even though the voltage is usually too low.

the electrolyte in the battery crystallizes at lower temps., giving a lower temp starting point for the recharge cycle.
