        "content": "No \u2014 according to the *official manual*, **you cannot use lithium AA dry-cell batteries** in the TASCAM DR-07XP. Only **AA alkaline** cells or **Ni-MH (rechargeable)** AA batteries are supported. ([manual.tascam.jp](https://manual.tascam.jp/dr-07xp/om/en/manual.html?utm_source=openai))\n\nHere\u2019s what the TASCAM documentation specifically says:\n\n> \u201cManganese and lithium dry cell AA batteries cannot be used.\u201d ([manual.tascam.jp](https://manual.tascam.jp/dr-07xp/om/en/manual.html?utm_source=openai))  \n> \u201cAlkaline or Ni-MH batteries can be used.\u201d ([manual.tascam.jp](https://manual.tascam.jp/dr-07xp/om/en/dr-07xp_om_e_va.pdf?utm_source=openai))\n\n---\n\n### Why Lithium AAs are Not Allowed\n\n- **Voltage and discharge profile differences**: Dry lithium (primary) AA batteries often start at a higher voltage and behave differently than alkaline or Ni-MH batteries. This can impact how the device measures battery level or could damage circuits not designed for that voltage. The manual\u2019s restriction suggests TASCAM designed *only* for alkaline or Ni-MH chemistry. ([tascam.eu](https://www.tascam.eu/en/docs/DR-07XP_OM.pdf?utm_source=openai))  \n- **Safety/precision concerns**: Using non-approved battery chemistries could cause unexpected behavior in power management, battery level readouts, or even safety issues in some worst-case scenarios.\n\n---\n\n### What You *Can* Use\n\n- **AA Alkaline** (non-rechargeable), **Ni-MH Rechargeable**: These are explicitly supported. ([tascam.eu](https://www.tascam.eu/en/dr-07xp.html?utm_source=openai))  \n- **USB bus power** or the **TASCAM PS-P520U AC adapter** are supported power sources. ([tascam.eu](https://www.tascam.eu/en/dr-07xp.html?utm_source=openai))\n\n---\n\nIf you were thinking of a specific type of \u201clithium\u201d battery \u2014 for example, primary lithium AAs (dry cell) or Li-ion rechargeable AAs with voltage-conversion built in \u2014 it\u2019s still risky. The manual\u2019s wording is clear: \u201clithium dry cell AA batteries cannot be used.\u201d That covers generic lithium non-rechargeables in the standard AA form. ([tascam.eu](https://www.tascam.eu/en/docs/DR-07XP_OM.pdf?utm_source=openai))\n\nIf you want, I can help you find a list of AA battery types that are safe, or suggest good NiMH or alkaline brands for the DR-07XP."
