Xiaomi 17T Pro BM7C Battery: 7000mAh Specs & Replacement Guide

The Xiaomi 17T Pro BM7C battery combines a 7000mAh typical capacity with a 6830mAh rated capacity on the teardown label. For repair shops and wholesale buyers, the useful starting point is the complete BM7C assembly: its label, physical layout and connectors must match the battery being replaced.

Xiaomi's official global specifications describe a 7000mAh typical silicon-carbon battery. The Xiaomi spare-parts listing independently identifies the Xiaomi 17T Pro battery as BM7C. The photographs below are original-resolution frames from a real teardown, rather than product renders.

BM7C battery specifications read from the label

Item	Observed specification
Handset / assembly model	Xiaomi 17T Pro / BM7C
Typical capacity	7000mAh
Rated capacity	6830mAh
Nominal voltage	3.78V DC
Charging voltage limit	4.55V DC
Label nominal energy	25.82Wh
Label typical energy	26.46Wh
Label chemistry wording	Rechargeable Li-ion Polymer Battery

These values are transcribed from the photographed original battery. The label's 25.82Wh agrees with 6.830Ah x 3.78V after rounding; 7.000Ah x 3.78V gives 26.46Wh. Typical capacity and rated capacity are different specifications, so an order sheet should identify which value it quotes. The 4.55V charging limit is a battery-side value, not a USB charger input specification.

Genuine rear view: cell markings and the complete assembly

The teardown turns the removed BM7C assembly over, exposing two pouch sections. Each visible rear marking reads 3425mAh, 12.95Wh and 3.78V. Those individual markings must not replace the complete assembly's front-label rating of 6830mAh / 25.82Wh or its 7000mAh / 26.46Wh typical specification. Their arithmetic totals are 6850mAh and 25.90Wh, which differ from the assembly label; this guide preserves both observations without presenting them as the same rating.

The two visible sections do not establish the assembly's electrical connection topology. Buyers should specify the complete BM7C battery and confirm the offered assembly's connector arrangement and electrical specification, rather than doubling the 7000mAh figure or treating a single pouch marking as the full replacement capacity.

Installed battery layout and replacement checks

The installed view shows where the BM7C battery sits relative to nearby flex cables and lower components during disassembly. Use the photographs to compare orientation, connection tails, insulation and packaging with the customer's original part. A similar outline or a shared 7000mAh capacity does not establish compatibility with another Xiaomi model.

Before confirming a Xiaomi 17T Pro replacement battery order, provide clear photographs of the original front label and connectors, the handset's exact model and region, and the required dimensions. Ask for sample specifications and inspect the offered assembly before committing to a larger quantity. Installation should follow appropriate service procedures for the device.

Xiaomi 17T Pro battery life: an independent reference

Notebookcheck's review, published July 28, 2026, reports 25 hours 59 minutes in Wi-Fi web browsing with Chrome 150; its comparison chart identifies the test as WiFi v1.3. This is a result for the reviewed complete phone, not a runtime guarantee for a replacement BM7C battery. Screen settings, workload, software, network conditions and battery condition affect actual endurance.

Charging specifications belong to the complete phone

Xiaomi lists up to 100W wired HyperCharge and 50W wireless HyperCharge for the handset, with 100W PPS support. These are manufacturer handset specifications and depend on suitable charging equipment and operating conditions. They do not establish the charging performance of an untested replacement battery.
