Built for the moments your battery actually matters
Battery Guard isn't a gimmick you forget about. It earns its place the moment you're far from a charger, or trying to make a battery last for years.
Working from a café
No outlet in sight? Set a 30% alert that's impossible to miss and a 15% full-screen warning, so you save your work long before macOS would ever say a word.
Making the battery last years
Set an 80% unplug alert, keep an eye on temperature, and let the health forecast tell you when capacity is really starting to slip — so your Mac's battery outlives its warranty.
Deep focus, no nags
Battery Guard dismisses macOS's repetitive low-battery banners and replaces them with a single calm alert at the one level you actually care about.
Presenting without panic
Before a talk, set a high alert threshold and watch live time-to-empty in the menu bar. No surprise shutdowns mid-slide.
Travelling light
On a long flight or train with no outlet, Battery Guard's live time-to-empty and a custom 25% alert mean you always know exactly how much working time you have left.
Battery at a glance
Pin a Battery Guard widget to your desktop and keep charge, health, and time-to-empty visible all day — no clicking into the menu bar to check where things stand.
Selling a used Mac
Export a one-page PDF battery health certificate showing capacity, cycles, and condition — proof for the buyer and a better price for you.
Heavy, hot workloads
Rendering, compiling, or gaming for hours? A heat alert warns you when the battery runs hot, and the temperature chart shows you exactly how warm things got.
One app, every scenario
Whatever your reason for caring about battery, Battery Guard has a feature built for it.
