Is this what it says in the menu bar?...cause if so...this can mean various things. 95% charge just means that the battery is 95% charged via it's current capacity. Capacity (runtime on a single charge) decreases as the battery gets older/more charge cycles.

So when brand new...this battery with 95% charge may have gotten 4.5 hours of runtime on one charge. But if the battery is old...and may have 500, 600, 700, or more charge cycles...then 95% could mean just 15 minutes of runtime.

Bottom line...we need more info. How many battery charge/discharge cycles does the battery have? If it's pretty high...you may need a new battery.

To determine the number of battery cycles...go to:

- Apple Menu
- About this Mac
- More Info
- System Report (depending on what OS version you are running)
- click on "Power" in the left margin list

Look for "Cycle Count".
