Battery / Starting Puzzle

2001 Sequoia, 3 year old battery, never been drained

Doesn't start this am. Only a clickclickclickclick from the starter. Radio isn't working, neither is the fan.

Jump start it and it fires right up. Park it. Find alternative transportation.

Tonight, find car where parked, (nothing done since jump start and moved aside) measure voltage: 11.9V. Try to start - turns half a turn and clickclickclick again. Measure voltage: 11.3V.
Jump start again. Measure voltage charging: 14.0V

Drive around block for 2 min. Shut down. Measure voltage 12.5V
Measure current draw (disconnect neg. cable and measure across to neg post): 4 mA.

Get back in - starts right up. Shut down and crank back up 3x, starts every time. Measure again: 12.5V (!)

Posts and cables are clean.

What do you guys think? I was going to buy a new battery, but the fact that it doesn't start at a 11.9V reading is odd along with the fact that it starts 4x in a row after only driving a mile to "recharge".

Thanks!
