The Reno 6 battery model name is BLP863 for the Oppo Reno6 5G, model number CPH2251, and the pack is sold as 4300 mAh typical. This rests on a parts listing that names the same phone, model number and capacity, so treat BLP863 as a strong lead rather than a final word. It is an Oppo part, and BLP is the family used for Oppo, Realme and OnePlus cells.
People also type this as "oppo reno 6 battery model name" or "reno 6 battery model number". Those two are not the same thing. The battery code is a short name such as BLP863, while the phone model number is the CPH code in your settings. You need both when you order. You can read BLP863 on the sealed Reno 6 5G only once a technician has opened it.
Quick facts
Step by step
Write down the model number of your phone
Open Settings, then About phone, and note the device name and the CPH number. If you cannot find it, type model in the Settings search bar, since menu names change with the software version.
Check the box or the invoice
The retail box label usually repeats the model number. Match it with the number in settings so you know you hold the Reno6 5G and not another Reno.
Have the back opened by a technician
The phone is sealed, so the cell label can be read only after the back panel comes off. The label should show
BLP863with the capacity and voltage.Compare the new pack before fitting
Put the new and old packs together. The code, the size, the weight and the plug on the flat cable should all agree.
Which phone takes the BLP863 pack
BLP opens every Oppo, Realme and OnePlus cell code, but tells you nothing about the Reno 6 5G itself. For the Reno6 5G, one listing names BLP863 together with the model number CPH2251 and a capacity of 4300 mAh. No other phone is confirmed for BLP863, so the table below is deliberately short.
| Phone | Model number | Status |
|---|---|---|
| Oppo Reno6 5G | CPH2251 | Matched to BLP863 by a parts listing |
| Oppo Reno6 Pro 5G | Not checked | Different phone, pack not confirmed as BLP863 |
| Reno6 4G (some markets) | Not checked | Sold in other markets, code not confirmed |
If you want the next phone in the line, the Reno 7 battery page gives its own code and its own facts.
Reno 6, Reno 6 Pro or Reno 6 4G: know which one you own
Three phones carry the Reno6 name, and the battery can change between them. The Reno6 5G in India is listed with a 4300 mAh pack. The Reno6 Pro 5G is a bigger phone with its own pack, and a 4G Reno6 was sold in some other markets. A pack that is right for one can be wrong in size, plug or charging design for the other.
The name on the back is not enough, because the word Pro is easy to miss in a quick look. Check the Reno 6 5G model number under About phone against the box. For this page the number to hold on to is CPH2251.
A customer brought a Reno6 and asked for a Pro pack, because the Pro box showed a high mAh number. The technician read the CPH number first, saw it was the plain Reno 6 5G, and ordered the pack matching the old cell. The bigger number on the box was the wrong lead.
Rated and typical mAh for BLP863
BLP863's 4300 mAh is the typical value in Oppo's Reno 6 5G specifications. Oppo packs often print a slightly smaller rated value on the cell label, and that smaller number is the minimum the cell must deliver. Read it from your own pack, since it is not confirmed here.
Watt hours for BLP863 are 4300 mAh times its voltage, over a thousand. As an example only, a 4300 mAh cell marked 3.87 V would come to about 16.6 Wh. Use the voltage printed on your label, not this example.
Never judge BLP863 by mAh alone. Reno 6 5G runtime depends on its screen, refresh rate, signal and what you run. Charge speed depends on the 65 W SuperVOOC adapter and cable, and heat slows it.
Where to read the Reno 6 battery model name on a sealed phone
Many owners go looking for the code in the Settings menu and do not find it. Reno 6 5G Settings shows the name, model number and on many builds a battery health line. BLP863 itself is on the cell label, so reading it needs the back panel off.
- On the box: the model number, which tells you the exact phone version.
- In Settings: the model number under About phone. Type battery in the search bar to find the battery page for your version.
- On the cell: the BLP code, the capacity and the voltage.
When the technician opens the back, ask for a clear picture of the cell label. You then hold the code, the capacity and the batch marks without a second visit.
Signs the Reno 6 battery is failing
| Reno 6 symptom | Cause behind it | Next step for BLP863 |
|---|---|---|
| Reno 6 percentage drops in jumps | BLP863 worn after many cycles | Check Reno 6 health and plan a BLP863 |
| Reno 6 switches off with charge left | Tired BLP863 cannot deliver peak current | Ask Oppo service to test BLP863 |
| Charging is slow and the body is hot | Heat, a poor cable or an ageing cell | Try the original cable, then have it checked |
| Reno 6 screen lifts or back bulges | BLP863 has swollen | Unplug the Reno 6 and go today |
On the Reno 6 5G, check apps and signal with our fast drain page before blaming BLP863. Then the health check shows how much capacity BLP863 has left.
Bulging, heat, leaking or a dent make BLP863 dangerous. Unplug the Reno 6 5G, keep hands off the cell, let it cool, and carry it to Oppo service. BLP863 spares printed well past 4300 mAh are dishonest; fit only one whose code matches the old cell.
Replacing the pack without a wrong fit
The Reno6 5G is sealed, so let a trained technician open it. Give the technician the phone name and the CPH2251 number, and ask them to compare BLP863 with the label of the old pack before they fit anything.
A new pack should pass a simple look test:
- Its weight is close to the old cell, and not noticeably lighter.
- BLP863 print is sharp with batch details.
- The capacity is near 4300 mAh. A far higher figure in a Reno 6 sized body is a false claim.
- The plug on the flat cable has the same shape and pin layout.

Codes people confuse with BLP863
All BLP codes look alike at a glance, and one wrong digit means a different phone. The later Reno models have their own codes, shown on the Reno 7 and Reno 8 pages. Never move a code from one Reno to the next because the model names are consecutive.
Our Oppo and Realme code table lists the rest of the BLP family. Faded print can turn a 3 into an 8 or a 6 into a 5, so angle the BLP863 label under a bright light before noting it.
Daily care for a fast charging Reno
This phone charges quickly, and quick charging makes heat. Charge the Reno 6 5G on a firm, cool surface, never under a pillow, and remove a thick cover once it warms. Charge the Reno 6 5G from its own 65 W kit or a matching one, and swap any lead that warms by the plug.
Holding the Reno 6 5G at full charge for hours, especially in hot weather, wears BLP863 faster. Unplugging near full when you can is a small habit that helps the pack last longer.
