Help us diagnose our Ford F150: what could be draining down the (new) battery overnight? We're suddenly seeing apparent battery drainage in our pickup truck, a 1994 Ford F150. Though the truck starts up fine, the dashboard battery gauge reads low immediately upon ignition, the windshield wipers are sluggish, and the dashboard lights are dim. We thought the old battery was likely dying, so we had it replaced with a new battery... but that hasn't solved the problem. [more inside]
I would like to learn more about large-scale UPS systems, particularly the battery strings used in traditional RBOC/Telco applications. These are the sort of beasts that use huge strings of 6V 220aH deep cycle batteries, or even large numbers of 2V 400aH batteries on very strong earthquake-resistant shelving wired up to create a 48V mega-battery. Can anyone point me to the most definitive reference materials on the subject?

iPhone battery life: I'm flying across the Pacific tomorrow with a 2 year old and a 5 year old. They are iPhone fiends (god help them), but I need to know if there is a huge difference in battery consumption between the education apps they usually play ("Find the sheep"..."Baaaa") and videos. I suspect that videos will use up battery life longer than these really simple apps, but I'm not sure. Anyone know?

I just changed my car's old dead battery with a new, just purchased one following the directions here. Even though I clamped the connectors down hard enough that I can't move either of them, the car seems to be completely dead --- it doesn't appear to be getting any power whatsoever. Any ideas what could be wrong? [more inside]

My 18 year old son went to Express Oil Change to have a new battery put in his 2004 Ford Explorer Sport Trac. His battery was dead and when jumped off, it would not hold a charge. They put an MTP-65 Interstate battery in and charged him $146 for the battery alone. With installation, charging system testing fee, and taxes, the total cost was $208.93. Does that sound high? I was expecting to pay half of that.
My Aspire 3680 (crappy laptop PC) doesn't want to hold a charge anymore, with either battery. How do I determine if it's my laptop, my batteries, or my charger? (I have a VOM and know how to use it).

Battery For Aging Laptop: OEM or 3rd Party? I need a new battery for my four year old Mac powerbook (old one discharges within 60 mins). Like the original, it lost its endurance after 2 years and currently discharges after 60 mins of use. There are few OEM batteries still around for this thing (though I did find one on eBay). But it occurs to me that while no Apple battery could possibly be fresh at this point, the 3rd party replacement ones MIGHT be more recently made. Though I'd usually hesitate to go with a 3rd party manufacturer on something like this. Any advice? FWIW, it's a Powerbook G4 15", and battery is A1045/A1078/A1148

How to keep iPhone usage stat from grossly exceeding actual usage and draining the battery accordingly?
Sometimes, my iPhone 3G usage statistics are totally out of line with my actual usage and the battery is drained accordingly.
