Where can I get a cheap(er) battery for my aging 2 year old Macbook?

Where can I get a cheap(er) battery for my aging 2 year old Macbook? I have tried Apple, but the price is pretty steep! I'm in Australia (Sydney specifically), if that makes a difference.

Help with Battery Backup

Does anyone know where I can find the operating software and a manual for an HP Powerwise 2100 Battery Backup? APC bought HP's battery backups unit in 1994, but this unit seems to work great. I want to control it from my PC but have no software and no instructions. I've visited all of the manual sites and software download sites I can think of.

Is my off-brand laptop battery toast?

My new off-brand laptop battery (Dell Latitude X1) suddenly stopped working after about three weeks of use. The BIOS says "The system could not communicate with this battery," and Windows says "No battery detected." Is there anything I can do besides shell out for an OEM battery?

How to freplace dead battery in sump pump?

Clueless homeowner question: Our sump pump (which has a battery for backup) is beeping and blinking, telling me to replace the battery. It looks like a car battery, but my son (he who knows how stuff works) is away ay school. What kind of battery do I get? Where do I get it? And, most scary, how do I (safely) unhook the old one and replace it with the new one. Don't assume I have even the most basic skills or knowledge.

Replace Toshiba M55 CMOS battery

Mrs. mysterious1der's laptop (M55-S331) won't keep time accurately. I've torn apart and repaired (board swaps, not actual board level repair) dozens of Dell laptops, but this is my first Toshiba.

iPhone Battery Charging

We've all been reading about the iPhone and its battery that's supposed to last 300-400 charges. How do they define "charge"? I usually charge mine every night, when the battery is at about 50%. Is that a "charge"? If I top my iPhone off when it's at 80%, is that a charge? What's the best way to preserve the life of my iPhone battery?
