    I've just use the app Battery Health. I'm seeing the health at 78% (I'm thinking 78% can't be too bad) but I'm seeing my MacBook run dead within 2 hours easy! I've got the screen brightness on the lowest, no back light keyboard. I'm not running power hungry apps (just browsing using Safari). I'm running the latest version of MacOS 10.13.4 (17E199).

    Is 78% really battery replacement time??? Thoughts or Experiences...

    Assuming the app is showing the same health that About this Mac | Below 80% is Apple criteria for replacing the battery under Apple Care and warranty. https://support.apple.com/en-us/HT204054. At the bottom is says.

    Battery warranty information
    Your Apple One Year Limited Warranty includes replacement coverage for a defective battery. If you purchased an AppleCare Protection Plan for your Mac notebook, Apple will replace the notebook battery at no charge if it retains less than 80 percent of its original capacity. If you don't have coverage, you can have the battery replaced for a fee.

    Yes, if your battery health drop below 80%, you could consider replacing the battery, particularly if you are no longer happy with your battery life.
    As jerryk suggested, you should compare with your System Information/Power tab, which will show you other information about the condition of your battery.
    How many charge cycles on your battery?

    Your battery has an estimated design life of 1000 cycles, so that's getting relatively close to end-of-life.
    I hear about batteries that can go a good amount beyond that point, but if you are already having battery problems, then that's the step you need to take - replace the battery.

    Thanks everyone for the messages. Looks like I'll be getting a battery replacement.
