        "content": "If you\u2019re referring to the *Mantis Q40* refreshable braille display / keyboard (commonly used by people who are blind), here are the details on battery life when it\u2019s **not connected to AC power**:\n\n---\n\n### \ud83d\udd0b Battery Specs & Expected Run Time\n\n- The device includes a rechargeable, removable Li-Ion battery rated at **3.7-volt, 2000 mAh**. ([fccid.io](https://fccid.io/XT5-BRQT40/User-Manual/Users-Manual-4802446.pdf?utm_source=openai))  \n- From manufacturer specs: battery life is rated at approximately **15 hours** under typical usage. ([aph.org](https://www.aph.org/app/uploads/2022/06/Mantis-Q40-Brochure-6-22.pdf?utm_source=openai))  \n- Independent reviews and user testing show a more realistic range: **12 to 17 hours**, depending on usage patterns, especially how much Bluetooth or WiFi is active. ([afb.org](https://www.afb.org/aw/21/8/17143?utm_source=openai))  \n\n---\n\n### \u26a0\ufe0f What Affects Battery Life\n\nReal battery life depends on:\n\n- **Wireless usage**: More Bluetooth / WiFi = more battery drain. ([afb.org](https://www.afb.org/aw/21/8/17143?utm_source=openai))  \n- **Display and keyboard activity**: Constant updates / typing / image-heavy content draw more power.  \n- **Settings**: Features like Sleep mode, Auto-power off, display brightness (if applicable), etc. ([aph.org](https://www.aph.org/app/uploads/2024/08/Mantis-Q40-EN-UG-2.3-accessible-UA.pdf?utm_source=openai))  \n- **Temperature and battery age**: Batteries perform worse in very cold or very hot conditions and will hold less charge as they age.\n\n---\n\n### \u2705 Practical Estimate\n\nSo, on a brand new Mantis Q40:\n\n- If you use it with moderate wireless activity (Bluetooth, occasional WiFi) and regular typing and display refreshes, you can expect somewhere around **12\u201315 hours** of continuous use.\n- If you minimize wireless usage, disable or reduce high-power features, let it enter sleep mode when idle, etc., you might get toward the higher end (16-17 hours). ([afb.org](https://www.afb.org/aw/21/8/17143?utm_source=openai))  \n\n---\n\nIf you meant a *different* \u201cElectonic Mantis 40 keyboard\u201d rather than the Mantis Q40 model, let me know and I can check battery specs for that one."

Below are the details.\n\n---\n\n### \ud83d\udd27 What the Manufacturer\u2019s Documentation Says\n\n- The battery pack is **removable** and you can access it by removing **two Phillips-head screws** on the back of the device. ([device.report](https://device.report/manuals/mantis-q40-user-guide-aph?utm_source=openai))  \n- You can purchase a replacement battery pack commercially through HumanWare (APH\u2019s partner) designated specifically for the Mantis Q40. The specification is: Li-Po / Li-Ion, **3.7 V nominal, 2000 mAh**, dimensions about 5 \u00d7 31 \u00d7 120 mm. ([store.humanware.com](https://store.humanware.com/hus/mantis-q40-battery-pack.html?utm_source=openai))  \n\n---\n\n### \u26a0\ufe0f Important Warnings & Warranty Implications\n\n- The device manual says: \u201cRisk of explosion if battery is replaced by an incorrect type.\u201d So you must use the specified battery type from the manufacturer or one that matches exactly in specifications. ([fccid.io](https://fccid.io/XT5-BRQT40/User-Manual/Users-Manual-4802446.pdf?utm_source=openai))  \n- The warranty **does not cover** the battery pack itself. Warranty covers \u201call parts (except battery) and labor.\u201d ([aph.org](https://www.aph.org/app/uploads/2024/08/Mantis-Q40-EN-UG-2.3-accessible-UA.pdf?utm_source=openai))  \n\n---\n\n### \ud83d\udee0\ufe0f Practical Advice for Replacing the Battery\n\n- If you're comfortable using a small screwdriver and handling electronics gently, you can replace the battery yourself using the proper replacement pack.  \n- Use only the **official replacement battery** or one that matches exactly in voltage/current specs. Using something mismatched can cause safety risks or damage the device.  \n- Be aware of the voltage, charge management, and connectors \u2014 taking care not to damage internal components when opening or reassembling.  \n\n---\n\nIf you want, I can find links to current authorized replacement battery packs (with expected prices), plus walk you through step-by-step battery replacement if you plan to do it yourself."
