Most listings give the BLP845 battery model name for the OnePlus Nord CE 5G, sold as model numbers EB2101 and EB2103. BLP845 is a Li-ion polymer pack of 4500 mAh typical at 3.87 V, about 17.4 Wh. OnePlus sits in the Oppo group, so BLP845 follows the family pattern.
Be careful with the name. Some sellers print "Nord CE" for several different phones, and the later Nord CE 2 is a separate model. Listings for it do not agree on one code, so do not order a BLP845 for it without reading the label. Your Nord CE 5G is a sealed phone, so the code on the cell is visible only when a technician lifts the back panel.
Quick facts
Step by step
Read the model number of the phone
Open Settings, tap About device and note the model number. If you cannot find it, type model in the Settings search bar. Nord CE 5G listings show EB2101 or EB2103.
Have the old pack read when the back is open
Ask to see the cell label while the phone is on the bench with its back off. The characters
BLP845should be printed there along with voltage and capacity. Do not pull at the pack yourself.Hold the new pack next to the old one
Compare the code letter by letter, then the size of the pack, the position of the connector and the thickness. Same mAh alone proves nothing.
Judge the print and the weight
A genuine-looking pack has crisp print, batch marks and a weight near the old cell. If it feels like a feather and claims 6000 mAh, refuse it.
Which phone uses the BLP845 battery model name
The BLP prefix is shared across Oppo, Realme and OnePlus, and it never names a phone by itself. For BLP845, most listings point to one phone: the OnePlus Nord CE 5G, in both of its model numbers.
| OnePlus handset | Model number | Status |
|---|---|---|
| OnePlus Nord CE 5G | EB2101 | Matched by most listings |
| OnePlus Nord CE 5G | EB2103 | Matched by the same listings |
| OnePlus Nord CE 2 5G | IV2201 | Listings disagree, read the label |
| Other Oppo or Realme phones | Not named | Not confirmed |
A few sellers add a loose line saying the pack suits other Oppo and Realme phones. No phone name comes with that claim, so treat it as empty talk. Go by the phone you actually hold, not by a vague promise.
Nord CE 5G or Nord CE 2: the mix-up to avoid
Both phones carry a 4500 mAh figure in adverts, so a counter helper may think the pack is shared. That is the trap. Equal mAh says nothing about code, shape or connector. The Nord CE 2 is covered on its own Nord CE 2 page, which deals with BLP903. That kind of slip is exactly why the label must decide.
A customer came in with a dead Nord phone and asked for a 4500 mAh pack. The shelf had two packs of that size. Opening the Nord CE 5G, the technician read BLP845 and put the other pack aside. That phone was an EB2101, which matched.
Rated and typical figures for BLP845
Adverts for the phone quote 4500 mAh. That figure is the typical capacity. Several parts listings of BLP845 show 4400 mAh instead, and the gap of about 100 mAh is the usual difference between a rated (minimum) and a typical number. Which number appears on your BLP845 depends on the batch, so read your own cell.
BLP845's energy: 4500 mAh by 3.87 V, over a thousand. That gives about 17.4 Wh, or about 17.0 Wh for the 4400 mAh figure. Both describe the same pack.
How long the phone runs depends on screen use, signal, brightness and apps. The Nord CE 5G's 30 W Warp charger sets its charge time more than mAh does.
Codes that look close to BLP845
Within the BLP family the numbers differ by one or two digits, and a misread digit sends you to the wrong phone. Check these pages before trusting a pack marked with a neighbour code.
- BLP841 sits just four numbers below and has its own phone list.
- BLP903 is a code that some listings attach to the Nord CE 2 line, but listings disagree.
- BLP923 is another popular pack with a separate list of phones.
Faint printing can turn 8 into 3 or 5 into 6. Tilt the BLP845 label toward a bright lamp or request a close up photo. The hub with every BLP code helps when your own number is unreadable.
Signs your pack is wearing out
| Nord CE symptom | Likely reason | Next step for BLP845 |
|---|---|---|
| Nord CE percentage drops in jumps | Aged BLP845, lower real capacity | Test the pack, then plan a new one |
| Nord CE 5G quits with 15 to 30 percent left | BLP845 voltage dips under load | Have OnePlus service check the BLP845 |
| Screen edge lifts or back gap grows | Swollen cell | Unplug the Nord CE 5G and get help today |
| Nord CE hot while idle | Worn BLP845, bad cable or busy app | Remove the case, unplug, get it tested |
Apps and a weak network explain most Nord CE 5G drain, so read our page on drain before doubting BLP845. You can then judge wear with a proper battery health check.
Once BLP845 puffs, scorches, seeps or dents, fire is possible. Unplug the Nord CE 5G, avoid touching the cell, allow it to cool and have OnePlus service inspect it. BLP845 copies often print false mAh, so buy BLP845 and nothing else.
Getting the pack changed safely
The Nord CE 5G is not built for casual opening. Adhesive, a thin flex cable and a fragile screen make it a job for a trained hand. Choose OnePlus service or a reputable shop and give them EB2101 or EB2103 with BLP845.
- Ask to see the old BLP845 before it is thrown away.
- Ask for the new BLP845's plug to be checked before the back closes.
- Ask what warranty, if any, the new pack carries and get it in writing.
Fitting steps and what to ask a technician are covered in how battery replacement works.
Write the code and the capacity from the old cell in your phone notes. A second visit later then needs no guesswork.
Daily habits that keep a 4500 mAh pack healthy
Heat harms BLP845 more than charge cycles do. Do not game while the phone is plugged in, and do not leave it on a sofa, bed or car dashboard while charging. A tight case can trap warmth, so remove it when the back feels hot.
Charge the Nord CE 5G with its Warp adapter or one rated equally, and bin a cable whose plug warms. Regular top-ups from 20 to 80 percent are gentler than running to zero. If the Nord CE 5G still shuts off after a restart and full charge, BLP845 is the likely cause.
