Blinking/clicking after battery replacement - Subaru Outback Forums -
"After installing a new battery in a 1997 Subaru Outback Legacy, the console lights, radio light, glove box light and front and rear exterior lights (minus headlamps) blink/click rhythmically for about 10 seconds, then stop for about 3, then repeat into perpetuity." Solution: cycle lock unlock w/key fob or btn under dash.

MacBook Air 2011 Battery Life – 2 hours or 7 hours? | Mac Crazy
1. Making the processor just a little busier can burn down the battery surprisingly faster.
2. Flash (only enable it when you need it.)
3. Leaving applications open swallows battery.
4. Startup items, daemons, extensions or background processes.
5. Screen brightness affects power use, but the number of apps running has a much bigger effect.
