The BA33 battery model name is listed by sellers for the vivo Y03, model V2332, as a 5000 mAh pack at 3.91 V. A separate listing names the vivo Y28s (V2346), but its details are blank, so we treat the Y28s match as a lead only.
BA33 belongs to vivo's newer code style, two letters and two digits, used on recent budget phones. Older vivo packs carried short codes like B-O5, which is why some owners are unsure whether BA33 is a vivo code at all. It is.

BA33 battery model name searches
People search "ba33 battery model name" after reading the code off a loose battery or a repair slip. If you have only the battery and not the phone, compare it with the table above and remember that BA codes are vivo's. A BA33 found in a drawer should not be charged on its own with a loose cable; old lithium cells are safest handed in for recycling at a service centre.
vivo's newer two digit codes
Recent vivo phones use codes such as BA28, BA33, BA45, BA49 and BA61. The pattern makes them look related, and they are all vivo, but each is a separate part. A BA45 and a BA33 can both be 5000 mAh and still differ in size or connector, so the full code on the label matters.
Checking before you buy
Start with the V-number shown under About phone on the Y03. If it reads V2332, the Y03 match applies. Then ask the repairer to read the BA33 sticker on the old cell, which shows 3.91 V and a rated capacity near 5000 mAh. A pack labelled only "for vivo Y03" without the code is a generic copy.
Budget phones like the Y03 are often charged overnight on beds and sofas. If the phone has started to feel warm while idle or the back is lifting, stop charging it and get the BA33 checked; a damaged cell can catch fire.
Battery life on the Y03
Built around a frugal chip and a 90 Hz HD+ panel, the Y03 stretches its 5000 mAh across a day without trouble, and across two when used lightly. It charges at 15 W, so expect around two and a half hours to full. See our 5000 mAh phones page for what this size means in daily life.
Where to replace it
As a recent phone, the Y03 is often still under warranty, and a vivo service centre will replace a faulty battery. Outside warranty, choose a genuine BA33 from vivo or a trusted shop. Our vivo code index lists other cells if the label on your Y03 shows another code.
What the 3.91 V rating means
Newer cells run at a slightly higher nominal voltage, 3.91 V instead of 3.85 or 3.87 V. That lets them hold a little more energy at the same mAh. When comparing two packs, multiply mAh by volts: a 5000 mAh cell at 3.91 V stores about 19.5 Wh, a touch more than an older 5000 mAh cell.
Y03 or Y28s: which BA33 claim to trust
The Y03 match comes from several sellers who print the V2332 model number and full specs. The Y28s match comes from a single listing whose details are mostly blank. If you own a Y28s, have the cell read first; it may well carry a different BA code.
