BatDev: Batteries & Devices helps you keep rechargeable devices in working condition for many years. The app focuses on battery health by tracking periods of active use, idle storage, and scheduled maintenance.

🔋 Active use means continuous charge and discharge cycles, for example when a scooter or tool is used daily.
💤 Idle storage means the device is not used for weeks or months, such as a scooter stored during winter.
In idle mode, batteries still require periodic service. BatDev reminds you to perform a discharge–charge cycle so the battery does not degrade while unused.

📊 For every device you add, BatDev records a history of usage and maintenance. You can view this history in tables and graphs: how long the device was actively used, how long it was idle, and when maintenance cycles were performed. This makes it easy to see patterns over time and understand how well you are caring for your batteries.

📝 Notes can be added to any date in the battery’s history. For example, you can record the real measured capacity of a battery and track its gradual degradation. Over months and years, these notes build a clear picture of battery performance.

💡 The benefit is simple: longer battery lifespan, fewer expensive replacements, and devices that are ready when you need them. Without proper care, a device left unused for months may fail when you try to use it again, forcing you to buy a new battery or even a new device. With BatDev, you avoid these surprises.

BatDev is suitable for all rechargeable devices, from toothbrushes and drones to scooters, tools, and power stations. Add them to the app, follow reminders, and keep them in reliable working condition for years.
