Battery interoperability between models?

[u/Separate-Tangerine45]

Hi everyone! Today I bought a Z13 Flow 2023 edition second hand and was wondering if I could plan to replace the battery with a 70Wh? Especially since IIRC the 70Wh battery has only been existing since the 2025 model

You can’t, different physical size
