Compatibility
Fits the Xiaomi Redmi 7A, model numbers M1903C3EG, M1903C3EH, M1903C3EI and MZB7995IN. It does not fit the Redmi 7 or the Redmi 8A, which use different batteries. Check your model in Settings > About phone, and if you have the phone open, confirm the old battery label reads BN49.
How to fit the battery safely
Power the phone off, then remove the back cover with gentle heat and a thin pry tool. Unscrew the plate over the battery connector and disconnect the battery before anything else. Lift the old cell slowly using its pull tabs, or a little isopropyl alcohol under the edges, and never bend or puncture it. Fit the new battery with fresh adhesive, reconnect it, refit the cover and charge fully. Do not use a swollen or damaged battery.
