Create Custom Battery Alert Sounds with AI

Battery Notifier ships with 14 built-in sounds. But what if you want something that's yours — a sound that fits your vibe, your workflow, your personality?

You can generate custom notification sounds using AI tools like Google Gemini, then import them straight into Battery Notifier. Here's how.

Step 1: Generate a sound with Gemini

Go to Google AI Studio or open Gemini in your browser. Ask it to generate a short audio clip. The key is being specific about mood, length, and instrument.

Here are prompts you can copy-paste:

For full battery (happy, done charging)

Gentle chime:

Generate a 2-second notification sound: a bright, warm two-note chime using a marimba. Rising pitch. Should feel satisfying, like completing a task. Export as WAV.

Nature-inspired:

Create a 3-second audio clip of a soft bird chirp followed by a gentle wind chime. Calm and pleasant — meant to say "your battery is full, unplug now." WAV format.

Minimal beep:

Generate a 1.5-second clean digital beep — two short ascending tones, sine wave, no reverb. Friendly and non-intrusive. Like an elevator arriving. WAV format.

Playful:

Create a 2-second sound effect: a cheerful "ding-ding" using a xylophone, like a game reward. Light and fun, not loud. WAV format.

For low battery (urgent, needs attention)

Soft alert:

Generate a 2-second low battery warning sound: two descending piano notes, minor key, slightly urgent but not alarming. Should make you look at your screen. WAV format.

Rhythmic pulse:

Create a 3-second alert: three short pulses of a soft synth bass, evenly spaced, low pitch. Like a heartbeat slowing down. Feels like "time is running out" without being stressful. WAV format.

Classic warning:

Generate a 2-second warning tone: a double-tap on a hollow wooden block, followed by a quiet descending hum. Noticeable but calm. WAV format.

Dramatic (for heavy sleepers):

Create a 3-second alert sound: starts quiet with a low drone, then a sharp metallic ping at the end. Should cut through background noise. For people who miss subtle notifications. WAV format.

Step 2: Download the audio file

Gemini will generate the audio. Download it — you'll get a .wav or .mp3 file. Battery Notifier supports .wav, .mp3, .m4a, .ogg, .flac, and .aac, so most formats work.

If the file is too long or too loud, trim it with any free audio editor (Audacity, the built-in Voice Recorder, or even an online tool like AudioTrimmer).

Keep it under 5 seconds. Shorter is better for notifications.

Step 3: Import into Battery Notifier

1. Open Battery Notifier
2. Go to Settings
3. Under notification sound, choose Custom
4. Browse to your downloaded audio file
5. Done — preview it and adjust volume if needed

You can set different sounds for full battery and low battery, so your ears know which alert it is without looking.

Tips for good notification sounds

• Keep it short. 1–3 seconds is ideal. Anything longer gets annoying after the 50th time.
• Avoid loud starts. A sound that begins softly and peaks is less jarring than one that blasts immediately.
• Test it at low volume. If you can still identify the sound at 20% speaker volume, it's a good notification sound.
• Make full and low sound different. Use rising tones for "full" and descending tones for "low" — your brain learns the pattern fast.

Why bother?

The default sounds work fine. But a custom sound you actually like hearing means you're more likely to respond to it instead of instinctively dismissing it.

It takes five minutes. Make it yours.
