Battkeep
Battery Health Monitor
Battkeep puts your battery's full picture one click from the menu bar. It is a lightweight menu bar utility that reads your battery's health straight from the hardware. The menu bar shows your live charge percentage, and the popover lays out health as a percentage of design capacity, cycle count, a plain-English condition rating, charging state, time remaining, temperature, voltage, amperage, exact capacity in milliamp hours, and a 24-hour charge history chart. It reads the same hardware service macOS itself uses, refreshed continuously, with no network connections and no data collection.
Features
Battery Health From the Hardware
Battkeep reads your battery's current full-charge capacity from the hardware and compares it to the capacity it shipped with, so you see your health as a precise percentage, straight from the hardware.
Cycle Count
Every charge cycle wears a battery a little. Battkeep shows your exact count so you can track wear against Apple's rated lifetime for your Mac.
A Plain Condition Rating
Good above 80 percent health, Fair from 60 to 80, Service Recommended below that. You will know your battery is fading long before it fails.
Live Electrical Details
Temperature in Celsius and Fahrenheit, live voltage, current draw in amps, and exact capacity in milliamp hours, refreshed continuously.
24-Hour Charge History
A chart of your battery level over the past day while Battkeep runs, so you can see how the day actually drained.
No Permissions Needed
Battkeep reads the public IOKit battery service. It makes no network connections, collects no data, and needs no special system permissions.

Frequently Asked Questions
How do I install Battkeep?
Download Battkeep from the Mac App Store. After installation it appears in your Applications folder. Launch it and it will appear in your menu bar.
Why does Battkeep's health percentage differ from System Settings?
Both read the same battery. System Settings presents a rounded summary figure, while Battkeep shows the arithmetic to one decimal place, dividing the battery controller's current full-charge capacity by its design capacity and refreshing continuously. The two can land a point or two apart.
Does Battkeep work on a desktop Mac?
It runs, but there is nothing to monitor. The menu bar shows a placeholder and the popover reports that no battery is installed.
Does the charge history persist between launches?
No. History is kept in memory only and clears when the app quits. It fills back in as Battkeep runs.
Can Battkeep limit charging to protect the battery?
No. Battkeep is a monitor, not a charge controller. It reads and reports, and it never changes how your Mac charges.
Does Battkeep collect my data?
No. Battkeep makes no network connections and collects no personal data. The only value it stores is a small local counter that decides when to ask you for an App Store review, and that never leaves your Mac.
Is there a subscription?
No. Battkeep is free. There are no subscriptions, in-app purchases, or recurring fees.
How do I uninstall Battkeep?
Drag Battkeep from your Applications folder to the Trash. No extra cleanup is needed.
