I have a 850va 425w UPS battery backup with only 2 outlets. There is a small server, speakers, home theater projecter, lcd monitor, and router connected to a power strip. The power strip and a desktop plug into the UPS. Is this setup safe? I am concerned about short 1-second interruptions caused by bad electrical connections rather than power outages.

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. This doesn't seem like a settings issue but rather some application or service getting "stuck" and not turning off when the phone is locked. Any ideas what I can do to address this? [more inside]

Dead battery--is there a problem with my car? [more inside]
So the modern practical uses for these are in guitar effects, alarm clocks, and smoke detectors. leave your effects on and they die in a couple of hours. as a backup to your alarm clock, it dies in four or five hours (not even powering the LCD). i have no idea how long these things last in a smoke detector, but my guess is the next housefire and i'm a dead man. why do these batteries suck so bad? why do we still use them? why hasn't science come up with anything better?

I need to buy a new battery for my Dell Inspiron 6000, and I've found two options: A and B. Obviously A is more expensive, but it has a higher mAH. I by default prefer the longest battery life possible, but I also don't know jack about laptop batteries. Searching the google has given me only whiffs and bits of information. Tell me hive, is 8000mAH better than 6600mAH enough to warrant $20 more? What can I expect from each, very roughly, in terms of hours of continuous use between charges? Also, feel free to inform me that A and/or B are terrible sites I should not buy from.
