here you go...im talking about the thing all the way at the bottom

Stats battery section:
This section shows various information about your Macs battery. This section is only visible if you actually have a battery and wont appear on desktops.
Percentage
The current battery charge as a percentage. This is also shown as a bar at the bottom of the section.
Time
Time left using the battery, time until charged, or Charged if the battery is fully charged.
Source
AC if the Mac is connected to mains power, or Battery if the battery is being used.
Status
This shows if the battery is charged, charging or draining.
Battery Health
This is a comparison between your current battery capacity and capacity of it when it was new. For example, if your battery lasted 5 hours when it was new, a figure of 50% suggests you should get 2.5 hours out of your battery now.
Cycles
The amount of battery cycles the battery has had. One cycle is defined as a complete discharge and charge of the battery, but partial discharge and charges also count. So, two half discharge and charges are the same as one complete discharge.
I'm thinking it's the Percentage display that you are making reference to.
