Ask any spare part shop for the BN5P battery model name and they will hand over a Redmi Note 13 5G pack, which print either 5000 mAh, Xiaomi's advertised number, or 4900 mAh. One seller also mentions the Note 13 4G, but most give that phone a different pack, so treat BN5P as a 5G battery unless your own label says otherwise.
The Note 13 range launched with several near-identical names, and getting the right battery depends on knowing exactly which one you hold.
Quick facts
The phone behind the BN5P battery model name
BN5P is listed for the Redmi Note 13 5G, including Chinese model codes 2312DRAABC and 2312DRAABG. India units share the design. A listing that names 23090RA98C, a Note 13 variant sold elsewhere, also uses BN5P at 4900 mAh. We have not seen a reliable source giving BN5P to the Note 13 4G or the Note 13 Pro.
Note 13 4G, 5G and Pro: three different batteries
| Phone | Battery code |
|---|---|
| Redmi Note 13 5G | BN5P in most listings |
| Redmi Note 13 4G | Different pack, check label |
| Redmi Note 13 Pro 5G | Different pack, check label |
Codes from nearby years, such as BN5J for the Note 12 5G and BN5U for the Note 14 5G, show how one letter separates generations.
BN5P label details
A genuine BN5P sticker carries the Mi or Xiaomi logo, the code, a nominal voltage near 3.89 V, a charge limit around 4.48 V, the rated capacity and a serial. Packs sold without a logo can be fine if they come from a known supplier, but the code must be printed, not handwritten.
How to check before ordering
Xiaomi's About phone screen names the model; All specs beneath it shows the full code. If it reads 5G and starts 2312DRA, BN5P is the pack. The cell sits under a glued glass or plastic back, so the label is only visible once a technician opens it.
A Note 13 5G that becomes hot while idle, or whose back starts lifting, needs its battery checked before the next charge. A swollen cell must not be pressed or punctured; leave the removal to a service desk.
4900 versus 5000 mAh on BN5P
Both figures belong to one battery: 5000 mAh is what Xiaomi advertises, 4900 mAh the minimum the cell must deliver. One listing gives 3.89 V for the pack, which makes the energy roughly 19 to 19.5 Wh. A seller offering a BN5P at 6000 mAh is inflating the label.
Everyday battery life
The Note 13 5G pairs its 5000 mAh battery with a 120 Hz AMOLED screen and a 6 nm class chip, so most people finish the day with charge left. The 33 W charger fills it in roughly an hour. If yours suddenly drains overnight, a background sync or a stuck app is more likely than a failed cell in a phone this new. Our drain checklist walks through the usual causes, and the Redmi code index lists every BN pack.
What to expect from a BN5P replacement
Because the Note 13 5G is fairly new, most owners will not need a battery for a couple of years. When the time comes, a Xiaomi service centre is the safest place, since the glass back and the in-display fingerprint sensor need careful handling. Ask for a pack with BN5P printed clearly and a recent batch date. After fitting, the phone should again reach the end of a busy day. If it does not, the problem may be software or a weak network rather than the new cell.
Keep the Note 13 5G away from heat while it charges, and use the bundled 33 W adapter. That alone keeps the pack healthy far longer than any app.
