Laptop Battery Technology

It’s amazing stuff. My laptop battery tells me the percent charged, remaining capacity (in Watt-hours), full charge capacity, voltage, current, temperature, cycle count, manufacturer, manufacture date, first used date, serial number, and so on.

My battery’s currently at 30 degrees Celsius = 86 degrees Fahrenheit. It also has a full charge capacity that exceeds its design capacity. Always a good thing.

Today I saw these rechargeable Ni-MH AA batteries with built-in USB chargers. It’s quite amazing and it’s really cool that sort of thing fits together perfectly. Wouldn’t it be awesome if it gave you similar data on your laptop when you plugged it in for charging?
