Battlert: Battery Health Alert

Battlert is your all-in-one battery health guardian, smart charge alarm, and real-time charging monitor. Built to extend the lifespan of your device's battery, Battlert alerts you when your battery is charged, prevents destructive overcharging, monitors overheating, and measures real battery capacity (mAh).

⚡ WHY BATTERY HEALTH MATTERS
