Spare part listings usually link the BN5H battery model name to the Xiaomi group. They match it with the Redmi Note 11E, the POCO M4 5G and the POCO M5, and each of these phones has a 5000 mAh typical battery. Sources do not fully agree. Treat the phone list as a first hint, not as proof. The label printed on your battery decides the matter.
The code is sometimes typed as "bn 5h battery model name", with a gap in the middle. That is the same code. Check the final letter with care. BN5G, BN5J and BN5D sit right next to it in the code list, and each one suits a different set of phones. The code cannot be seen from the outside. It is printed on the cell under the rear cover. On a sealed phone, a technician must take off the back panel to reveal it.
Quick facts
Step by step
Write down the phone name and model number
Open Settings, then About phone, and note the device name and model number. If the number is not on the first screen, type model in the Settings search bar.
Ask for the old label to be read aloud
Once the back is open, the technician should find
BN5Hon the sticker, beside the capacity line. Ask for a photo of it before the pack goes in the bin.Compare the new pack with the old one
Put both packs on a table. The code, the outline, the flex cable and the connector end should all look the same.
Weigh the pack and inspect the print
A good pack has sharp print, batch marks and a weight close to the old one. A very light pack with a big mAh claim is a red flag.
Which phones the BN5H battery model name points to
Xiaomi uses BN on many Redmi and POCO cells, yet the letters name only the maker group. Spare listings for this code name the Redmi Note 11E, the POCO M4 5G and the POCO M5. Phones that share a code can still differ by version or region, so each of these pairings needs a check against the label.
| Phone | Status | What to do |
|---|---|---|
| Redmi Note 11E | Named in the usual listings | Compare with the label on the old pack |
| POCO M4 5G | Named in the usual listings | Compare with the label on the old pack |
| POCO M5 | Named in the usual listings | Look at the sticker before ordering |
| Redmi 10 5G and Redmi 11 Prime 5G | Not confirmed here | Do not assume, read the code |
| Redmi Note 11 and Note 11S | Different phones | See their own page |
The Redmi Note 11 family is easy to confuse with the Note 11E by name alone. For the Note 11S code, open its own Note 11S page and do not borrow it from here.
How to confirm BN5H before you pay
A match from a spare list is a fair start, but a repair counter handles many batches. Confirm in three small moves: the phone name, the phone's model number and the sticker on the pack in hand. If all three agree with this page, you can order that code with confidence.
The owner of a Redmi Note 11E wanted a new battery, and the counter showed two packs. One was marked BN5H and the other carried a nearby code. The technician asked for the model number first, then opened the back. The old label settled it in under a minute, and the wrong pack went back on the shelf.
If the phone was opened earlier, the pack inside may already be a replacement. Its sticker could then show a different code, which is a reason to inspect the connector with extra care. The guide to locating a battery code lists each place a code can appear.
Rated and typical capacity of this 5000 mAh pack
The usual capacity listed for BN5H is 5000 mAh. Ads and spare part listings quote this value. Phones from the Xiaomi group may also carry a second value, called the rated (minimum) capacity, and it is a little lower. No BN5H rated figure has surfaced in our sources, so the sticker on your own Note 11E or POCO M5 pack is the reference.
Energy in watt hours needs the voltage, and the voltage of this code is unconfirmed, so no watt hour value appears here. If your sticker shows the volts, multiply the mAh by that number and divide by 1000. Use that result when comparing packs, not mAh alone.
How long a phone runs in a day depends on its processor, screen, brightness and network signal. Two phones that both have 5000 mAh may give quite different results. Use a new battery for one full week before you decide if it is good.
Neighbouring codes people mistake for BN5H
One wrong letter causes most bad orders. The codes listed below are close to BN5H in the same family. Each one fits its own set of phones, so open the page that matches the code on your label.
- BN5G differs only in the last letter. Never swap the two.
- BN5J and BN5D are other close neighbours, each with its own phones.
- BN5R is another 5000 mAh typical code, proof that equal capacity does not mean the same pack.
- Redmi 10 Prime battery page is the place for the Redmi 10 Prime, which has separate details. It is a different phone from the Redmi 10 5G.
Faint print can make an H look like an N or M. Read the sticker in bright light, and ask for a close photo if needed. Every code of this family is gathered in the Redmi battery list.
Signs a BN5H pack is wearing out
| Symptom | Likely reason | Next move |
|---|---|---|
| Charge drops quickly on light use | The cell has aged and holds less | Run a health check, then decide |
| Note 11E quits at 20 to 30 percent | Tired BN5H under sudden load | Have a technician test it |
| Cover rises at the edge or display bulges | Pack is swelling | Unplug and visit a service counter today |
| Body feels warm while idle | Busy app, poor signal or a faulty pack | Restart, remove the cover, keep watching |
Do not blame the battery too soon. First read why batteries drain quickly, as a weak network signal and background apps are behind many such cases. Next, step through the battery health check stage by stage on your Note 11E or POCO M4 5G.
A BN5H that has swollen, leaked, dented or turned very hot is a genuine fire hazard. Pull out the charging cable and switch the phone off. Do not squeeze or bend the pack. Keep it far from heat of any kind. Visit the brand's service centre right away. Fake batteries often claim a false high capacity, so buy one that shows the right code and looks genuine.
Fitting a new BN5H pack safely
These phones have a glued back and a non-removable battery. Let a trained person do the opening with proper heat and tools. Carry the phone and its model number, and request that the code on the old sticker be checked against the new pack before fitting.
Spot a weak copy with these checks:
- It is clearly lighter than the pack that came out.
- The print is smudged and no batch marks are shown.
- The label on it promises far above 5000 mAh for the same body size. No real cell of that volume is able to deliver such a figure.
Keep the old pack on the counter until the new one is fitted and the phone has booted and charged once. That way a code or connector mismatch shows up straight away.

Daily care that keeps a 5000 mAh pack healthy
Heat does the most harm. Avoid charging on a bed, in a pocket or in strong sun, and slip off a heavy cover when the phone runs warm. Games and long video calls during charging add more heat, so pause them while the phone is plugged in.
Use a charger and cable suited to the phone, and swap a cable that overheats near the connector. Try not to leave the phone sitting at full charge for hours every night. A new pack ages slower when it is handled this way.
Frequently asked questions
Which phone uses the BN5H battery?
Parts listings link it with the Redmi Note 11E, the POCO M4 5G and the POCO M5. All three use a 5000 mAh typical battery. For certainty, check the print on the old battery before you buy its replacement.
What is the capacity of the BN 5H battery model?
BN 5H and BN5H mean one and the same code. The listing shows 5000 mAh typical, while the rated value on your label can be a little less.
Is BN5H the same as BN5G?
No. They differ in the last letter and have separate phone lists. Do not swap them, even when the capacity looks equal.
Can I fit a BN5H pack in a Redmi Note 11?
Do not assume it. The Redmi Note 11 is a different phone from the Note 11E, and its code is on its own page. Match the code first.
Does the Redmi 10 5G use BN5H?
That is not confirmed, so it is not listed here. Some phones in this group share hardware, but the label in your hand is the proof.
How can I tell a fake BN5H battery?
Watch for a light pack, blurry printing, no batch marks, or a capacity claim well above 5000 mAh. Place it beside your old battery and compare the two.
