Extend your laptop's battery lifespan with custom charge notifications. This program monitors your power status from the system tray and includes both installer and portable editions.
Vovsoft Battery Alert is a simple, user-friendly tool designed to help you optimize your charging habits and extend the lifespan of your laptop's battery. Modern lithium-ion batteries can degrade significantly if constantly kept at 100% charge or allowed to drain completely.
This utility resides on your desktop, providing a clear visual indicator of your current battery percentage and power status (Charging, Discharging, Fully Charged or AC Power). You can minimize the application to the system tray, where it monitors your device in the background and alerts you when the battery is low or sufficiently charged.
For flexibility, the software is available in two distinct editions: a standard installer for easy setup and a portable version that requires no installation, allowing you to run it directly from a USB drive or folder.
Key Features:
Prevent Overcharging: Set a "Full Battery" limit (e.g., 100% or 90%) to receive an alert reminding you to unplug your charger. This is crucial for maintaining long-term battery health.
Avoid Unexpected Shutdowns: Set a "Low Battery" threshold to ensure you have enough time to save your work and plug in before your laptop dies.
Customizable Sliders: Easily adjust the alert percentages using intuitive sliders to match your specific needs.
Sound Alerts: Receive immediate audio notifications when your battery reaches its low or full threshold. Personalize these alerts by selecting your own audio files, with support for all major formats including MP3, WAV, and WMA.
Real-time Monitoring: View the current battery charge percentage and power source status at a glance.
Lightweight & Simple: A clean interface with zero learning curve, designed to run efficiently without slowing down your system.
