The BA45 battery model name belongs to a Vivo pack, and most listings match it to the Vivo Y200i and the Vivo Y200T, sold as a 6000 mAh battery at 3.91 V. That match rests on only a few listings, so treat it as a strong lead and not a final word. Your own phone's battery sticker is the only real proof.
Some owners type "vivo ba45 battery model name" or "ba 45 battery model name". The gap or a missing hyphen changes nothing about the code. One thing can mislead you: older Vivo packs usually carry a short code like B-O5, while BA45 looks closer to codes seen on some Samsung and Motorola pages. Do not guess the maker from the first letters. Read the whole line on the sticker.
Quick facts
Step by step
Write down the phone name and model number
Open Settings, tap About phone and note the name and model number. If you cannot find it, type model in the Settings search bar.
Have the old battery label read out
With the back lifted,
BA45should appear on the sticker along with the mAh and voltage. Ask the technician to read the entire line, not just the first letters.Compare the connector and the shape
Hold the new pack next to the old one. Length, width, thickness and the plug at the end must all agree.
Judge the print and the weight
A genuine pack has crisp print and batch marks. If it feels far lighter than the pack you took out, return it.
Which phones the BA45 battery model name fits
Listings usually link this code to two phones, the Vivo Y200i and the Vivo Y200T. A third phone showed up in one listing, but its name looks like a typo, so it is not included here. If a phone name is doubtful, trust what is written on the battery you are holding.
| Phone | Status | Note |
|---|---|---|
| Vivo Y200i | Matched by most listings | 6000 mAh, listed at 3.91 V |
| Vivo Y200T | Matched by most listings | Check the model number before ordering |
| Other Y200 phones | Not confirmed | Different phones can use different packs |
| Older Vivo phones | Different codes | Often a short B-code, see the Vivo battery model list |
Vivo sells many phones whose names differ by one letter, and a few are made with more than one battery. Never assume a phone shares BA45 only because its name looks close.
6000 mAh listed: what the number tells you
The 6000 mAh figure is what the listings print, the sort of number used in adverts. Many makers also put a lower, minimum value on the sticker itself. For BA45 that lower number is not confirmed, so look at the label of the battery you hold.
You can compare packs by how much energy they hold. Six thousand mAh at a typical 3.87 V puts a BA45 near 23 Wh. For a 6000 mAh pack rated 3.91 V, the result is close to 23.5 Wh. Cells differ in voltage, so two 6000 mAh packs need not store identical energy. That is why mAh alone does not tell you everything.
Running time depends on the display, brightness, signal and the apps you use. A large cell helps, but it does not promise two days. Read what a 6000 mAh phone means in daily use for a realistic idea.
Confirming the code before you pay
You will find the code on a sticker fixed to the cell itself. The phone body is sealed, so a trained technician has to open the back to read it for you. Do this check before you order a new battery. Also request a clear photo of the old sticker and save it on your phone.
- The letters and numbers should read BA45 in full, with no extra characters you have not noted.
- The mAh and voltage lines should be close to what the listing gives.
- The phone's model number should match the phone the seller says the pack suits.
Send that picture to the person selling you the pack. A seller who can name the phone and the code from it is far safer than one who only says it suits every Vivo phone.
The wider method is in the guide to finding a battery model name.
Codes that look like BA45
Codes that start with BA and carry two digits appear for more than one maker on this site. They are unrelated, and each has its own phone list. BA10 and BA61 are different codes, and a pack marked with either is no stand-in for BA45.
- Vivo and iQOO packs often show the letter B, a dash and two more characters, for example B-O5.
- Samsung and Motorola codes follow their own patterns, gathered in the Samsung and Motorola battery list.
- Faint print can hide a digit or turn a 4 into an A. Read the code under a bright light.
A customer with a Y200 series phone asked for a pack from memory of the code. The counter had a battery with a similar BA label made for another maker. The technician opened the phone, read BA45 on the original label and turned the look-alike down.
Signs your BA45 pack is wearing out
| What you notice | Probable cause | Action |
|---|---|---|
| Percentage drops sharply within a few hours | Worn cell with reduced capacity | Test its health, then plan a replacement |
| Phone shuts off while charge still shows | Tired cell sags under heavy load | Get the battery tested |
| Gaps at the back panel or a raised screen edge | Swollen cell | Keep it off the charger and go for service today |
| Warm even when idle | A bad cell, poor signal strength, or some app that keeps running behind the screen | Reboot, take the case off, watch, then get it tested |
Many cases of fast draining come from apps or a poor signal, so check those first using our guide on fast battery drain. After that, do the battery health check and then decide whether the cell needs changing.
A battery that is swollen, leaking, dented or unusually hot is a fire risk. Turn the phone off and pull out the charger. Keep the phone far from heat, do not press or prick the battery, and visit a Vivo service centre the same day. Bogus BA45 packs promising extra mAh are everywhere, so only buy when the printed code matches yours exactly.
Getting a new BA45 pack fitted
This phone has a glued, sealed body, so the work is best left to trained hands. Visit an authorised Vivo outlet, or a workshop that people nearby recommend. Tell them the phone's model number and the code BA45 from the old label. More detail is on the page on mobile battery replacement.
Spot a poor copy by these points:
- The new one weighs far less in your palm than the old battery you removed.
- The printing looks smudged, and there are no batch marks.
- It promises well beyond 6000 mAh at the same size, which a cell of that volume cannot honestly deliver.
Once fitted, charge fully one time and watch for heat in the first few days. Ask for a bill that names the battery code.
Care habits for a large battery
A big pack takes long to fill, so plenty of owners leave the phone on the charger all night. Heat combined with many hours at a full level ages the cell faster. Charge the phone on a hard surface, away from bedding, and remove a bulky cover when the back feels hot.
Stay with the charger from the box or one of equal rating, and change a cable that warms near the plug. If your phone offers a charge limit, type battery in the Settings search bar to see what exists, because names differ by software version.
Frequently asked questions
Which phone uses the BA45 battery model name?
Many listings match BA45 to the Vivo Y200i and Vivo Y200T, and both phones are rated 6000 mAh at 3.91 V. To confirm, read the code on the old battery that sits in your own phone.
Is BA45 a Vivo battery?
The listings say so, and Vivo is the maker group on this page. The letters alone do not prove it, since other makers also use codes that begin with BA.
How many mAh is the BA45 battery?
It is listed at 6000 mAh. The lower minimum value that may be printed on the label is not confirmed, so check your own sticker.
Will a BA10 or BA61 battery work instead of BA45?
No, never assume so. Those codes belong to other phones and are not the same. Before you buy, make sure the full code and the connector type both match.
Where can I see the BA45 code on my phone?
It is on the battery sticker, visible only with the back open. Phone settings do not usually show the code.
How do I spot a fake BA45 battery?
Fake packs are often lighter, have smudged printing without batch marks, and promise much more than 6000 mAh. Weigh the new one against the old pack and compare the printing too.
