The surest way to learn how to find battery model name is to read the sticker printed on the battery itself, because Settings on most phones shows the phone's own model number and not the battery's code. On a phone with a removable back you can read it yourself. On a sealed phone, a technician reads it after opening the back panel.
This page explains where the code is printed, how the code families are built, how to read the capacity line, and what to do before you pay for a replacement. Each family has its own page with the exact phones for each code, linked below. The battery model name and the phone model number are two separate things, and mixing them up is the most common counter mistake.
Quick facts
Step by step
Write down the exact phone model number
Open Settings and look for About phone. If you cannot find the model number, type model in the Settings search bar. On an iPhone, go to Settings, then General, then About.
Compare it with the retail box and invoice
The box label usually carries the same model number. Phones sold in different markets can differ, so the box helps when Settings is unclear or the screen is broken.
Switch the phone off before touching the back
If the back is designed to come off, power the phone down first. If the back is glued or screwed, stop here and hand it to a technician.
Read the whole battery sticker
Note the code, the mAh line, the volts and any batch marks. Tilt the sticker under bright light when the print is faint.
Find the code family and open its page
A start such as
BN,BLPorEB-Btells you the maker group. Then open the page for that exact code and compare its phone list with your model number.Check the plug before the new pack goes in
Place the new pack beside the old one. The code, the size and the connector shape should all agree before it is fitted.
How to find battery model name: five places to look
Not every source is equally reliable. The sticker on the cell is the primary record, and everything else is a pointer towards it. Use the table to decide where to start.
| Place | What it gives you | Limit |
|---|---|---|
| Battery sticker | Full cell code, capacity, voltage and batch marks | Only visible with the back removed |
| Retail box and invoice | Phone model number and colour variant | Does not print the battery code on most boxes |
| Settings, About phone | Handset name and model number | Menu wording varies by brand and software |
| Service or repair slip | Code noted from an earlier swap | Only useful if the same phone was opened before |
| Maker's spare part listing | Code linked to a phone model | Needs the exact model number to search |
Settings may show battery health or capacity on some phones, but that is a different job. The code you need for buying is printed on the pack, so use Settings only to get your phone's model number.
How the code families are built
A code's opening letters identify the maker group. They never tell you the exact phone, so always confirm the phone list on the page of your code.
| Phone group | Code style | Sample |
|---|---|---|
| Xiaomi group: Redmi, POCO, Mi | Begins with BN, BM or BP | BN5R (Redmi 12 5G) |
| Oppo, Realme, OnePlus | BLP, then digits or a letter and digits | BLP805 |
| Vivo, iQOO | B, a hyphen, then two characters (vivo) | B-O5 |
| Samsung | Starts with EB-B, with a few other supplier codes | EB-BA217ABY and WT-N6 |
| Motorola | Two letters, two digits (four characters) | JK50 |
| Tecno, Infinix, itel | Starts with BL- | BL-49FT |
For whole families, start from Xiaomi, Redmi and POCO codes, Oppo, Realme and OnePlus codes, Vivo and iQOO codes, or Samsung, Motorola and other codes.
People often type a Vivo code as BO5 or B05. The proper written form has the hyphen, and the page for it explains the spelling.
Battery model name is not the phone model number
Two different labels cause most of the confusion. The phone model number identifies the handset and sits under Settings, on the box and on the phone's own regulatory label. The battery model name identifies the pack inside and sits only on the pack. A phone may show one, and the repair counter needs the other.
Variants matter too. Two phones in the same series can look alike and have the same mAh figure, yet carry different codes. A phone sold in one region can also differ from its sibling sold elsewhere. So the safest request to a technician is the full model number plus the old code, not a size or a capacity alone.
An owner whose phone shut off at 20 percent asked a counter for "a 5000 mAh battery". The technician asked for the phone's model number, then opened the back and read the label. The pack on the shelf had the same mAh figure but a different code and a different plug. Reading the old sticker saved a second trip.
Reading the capacity line on the sticker
Most stickers show a capacity in mAh. Most brands print a rated minimum on the cell and a typical figure in adverts. A pack sold as 5000 mAh typical may carry a slightly lower number on its label. Both are honest, but they are not the same figure, so say which one you mean when you compare packs.
Volts matter when comparing energy. Watt hours are the mAh multiplied by the volts, divided by 1000. As a worked example, 5000 mAh at 3.87 V is roughly 19.4 Wh. Apple states iPhone battery sizes in watt hours, while the mAh numbers come from filings and teardowns, as each of our iPhone capacity pages points out. For what the numbers mean in daily use, see what battery capacity means.
Screen time depends on chip, display size, refresh rate, reception, brightness and apps as well as mAh. Charging time depends on the charger's watts and the cable.

Mistakes that lead to the wrong battery
Most wrong purchases come from a short list of habits. Knowing them is half the cure.
- Near miss codes. A single changed character can point to another phone. Read every character.
- Right mAh, wrong code. Two packs can share a capacity yet differ in outline or plug, so the phone may refuse one.
- Wrong variant. Check the full model number, not just the phone's marketing name.
- Inflated capacity labels. A copy that claims far more mAh than the original in the same body is usually false. Weight, blurred print and missing batch details give it away.
- Trusting a list over the label. If your old sticker disagrees with a listing, your sticker wins.
The connector deserves a glance too. The small plug at the end of the pack must have the same shape and size as the socket on the phone's board, otherwise it cannot be fitted safely.
Other words people search for
Some searches near this topic mean something different. A battery bank is a power bank that charges the phone from outside. It is not the phone's own battery and has no connection with the code on your pack. Apps that promise to boost or add capacity cannot change the cell. Do not install such tools, and do not follow advice to freeze or open a battery. Searches for a scooter or car battery belong to a different subject, as this site covers only phone batteries.
Searches for "battery model" or "battery model number" almost always mean the code on the cell. Both phrases lead to the same answer: read the sticker, then match it to your phone model on the family page.
Before you replace anything
A weak battery is not always a dead one. Run a quick battery health test first, and look at fast battery drain causes, since a rogue app or poor signal can mimic an ageing cell. If the pack is truly worn, replacement and fitting tips explain the route.
Take a sealed phone to the brand's service desk or a technician whose work you know. Tell them your phone's model number and ask them to set the old label beside the new cell. Samsung owners can use the maker's support page to find official help.
Any phone battery that puffs up, runs unusually hot, leaks or is dented can catch fire. Unplug it straight away, do not squeeze, fold or puncture it, keep heat off and take the phone in for service. Replacements with made up capacity labels are widespread, so take only a cell whose code matches the old one.
Photograph the old sticker with a clear, close shot before the technician removes it. The code, volts and batch marks then stay with you for any later purchase.
Frequently asked questions
How to find battery model name if you cannot open the phone?
You cannot read the code from outside on a sealed phone. Get the phone's model number from Settings or the box, then open the family page for your phone's maker. For a firm answer, ask a technician to read the label with the back off.
Is the battery model number the phone's model number?
No. The phone model number identifies the handset. No. The battery model number is printed on the cell, while the phone model number is in Settings. You need the first one to search and the second one to confirm a match.
Can I see the battery model name in Settings?
Most phones do not show it. Settings usually gives the phone model number and sometimes battery health or usage. Search battery in Settings to see what your phone shows, but expect the cell code to come from its label.
What does a code starting with BLP or BN tell me?
It points to the maker group. BN, BM and BP codes are used by Xiaomi, Redmi and POCO, and BLP codes by Oppo, Realme and OnePlus. The letters do not name the exact phone, so check the phone list on the code's own page.
Will a capacity boosting app help me find or fix the battery?
No. Such tools cannot read the code from the pack and cannot add capacity to a worn cell. Only the battery label carries the code.
What if the sticker print is too faint to read?
Tilt it under bright light or ask the technician to photograph it. If it is still unclear, give the full phone model number and ask for the code to be matched from the maker's parts information before buying.
