While the portability of laptops is the main reason they’ve grown increasingly popular, that portability comes a price, namely rechargeable batteries. Not only do these batteries limit how long you can use the computer away from a power outlet, they gradually lose their ability to hold a charge.

Battery Health Monitor: Another freeware option, not quite as pretty as CoconutBattery, but gives you most of the same information. Battery Health Monitor has a grid at the top that shows you the power status of the laptop. When plugged in, the word “A/C Power” is bold for example; when on battery power, the word is grayed out.

Other indicators include “Battery Depleted” and “Not Chargeable,” neither of which you’ll want to see bolded. Battery Health Monitor also tells you how many charge cycles the battery has gone through as well as the current voltage the battery is delivering.

SlimBatteryMonitor: This piece of freeware is essentially a fancy replacement for Apple’s laptop battery icon.

While it does not provide any of the supplemental data the other options do, SlimBatteryMonitor’s main attraction is that it takes up less space in the menu bar than Apple’s built-in version and is much more customizable, particularly in the colors you can choose for the battery icon…

FreshBattery announced a new Legacy line of laptop batteries. The units are designed to provide batteries for notebook models that have been discontinued for three to 5 years, including older Apple PowerBooks and Apple iBooks.

According to Macworld News, the company claims that the laptop batteries are designed to meet or exceed the original manufacturer’s specifications. In the case of a Legacy battery for an original Apple PowerBook G4, FreshBattery has substituted the original 3600 mAH cells with 4400 mAH cells, resulting in a battery that adds an additional 40 minutes of run time between charges.

FreshBattery currently produces a battery range that covers the original “Clamshell” iBook G3s and goes back as far as the Wall Street and Pismo-era G3 PowerBooks. The Legacy battery line is currently priced under US$100 and available immediately.
