One parts seller lists the BA62 battery model name for the vivo Y29 4G, as a 5500 mAh replacement cell. That single parts listing is the only phone match so far, so treat BA62 as a lead rather than proof. No Samsung or Motorola phone was matched to BA62, even though this page sits in that group of the site.
People also type it as "ba 62 battery model name". Take care with the spelling on the label. vivo cells usually carry a short B, hyphen, two character code, so a four character code like BA62 looks unusual. Check the sticker on your Y29 4G cell before ordering. If the back is sealed, a technician has to open it for that.
Quick facts
Step by step
Write down the exact phone name and model number
Open Settings, then About phone, and note down the phone name along with the model number. If the page looks different on your phone, type model in the Settings search bar.
Separate 4G and 5G versions of the name
Check whether the box and the model number say 4G or 5G. A phone sold in two network versions may carry two different packs, so one word in the name can change the battery.
Have the back opened by a technician
On a sealed phone, only a technician with the right tools should lift the back. Do not pull or peel the pack yourself, because the glue and the flex cable tear easily.
Read the full code and the capacity line
The sticker should show the code, a capacity and a voltage. Check every character against
BA62, and note if it is written in another form.Compare the new pack with the old one
Put both packs side by side. The size, the connector shape, the print and the weight should look close. A pack with a noticeably low weight is a poor sign.
Which phone uses the BA62 battery model name
A single parts listing gives BA62 for the vivo Y29 4G at 5500 mAh. No second source was found to agree with it, and no phone maker page was found that prints the code. So the match is a starting point. Your own sticker has the final word.
| Phone | Status | Note |
|---|---|---|
| Vivo Y29 4G | Single listing | Listed at 5500 mAh; verify on the label |
| Vivo Y29 5G | Not confirmed | Different network version; do not assume the same pack |
| Other Vivo Y models | Not confirmed | A similar size does not prove a shared code |
| Samsung or Motorola phones | No match found | Samsung codes start EB-B; Motorola codes use two letters plus two digits |
The code also does not follow the usual Vivo pattern, which is why a careful check matters. The usual vivo style is explained on our vivo code list, and other makers' codes sit in our Samsung and Moto list.
What BA62's 5500 mAh tells you
The listing gives BA62 as 5500 mAh without saying whether that is typical or rated, and vivo stickers often show a lower rated number. Read both from the sticker of your pack, and do not trust a seller's text alone.
BA62's energy in watt hours: mAh times voltage, all over a thousand. No voltage is confirmed for BA62, so read it off the sticker. As an example only, a pack marked 3.87 V would give 5500 mAh x 3.87 / 1000, which is about 21.3 Wh.
Screen time depends on the chip, brightness, display, signal and apps, so a bigger number alone does not promise two days. Y29 4G charge time depends on the adapter wattage and cable.
Confirm the code before you pay
Follow the order below and you will rarely buy the wrong BA62.
- Get the Y29 4G model number from About phone.
- Have a technician open the Y29 4G and read the old BA62 sticker.
- Photograph the BA62 sticker with code, capacity and voltage visible.
- Ask for a new pack that shows the same code and a capacity close to the old one.
A Y29 owner asking for "a Y29 battery" was offered a pack of the right size but the wrong code. The old sticker, after the back came off, showed a code that did not match, so the pack went back. The Y29 name alone had not been enough.
Keep the photo of the sticker in your phone gallery. A photo of BA62 avoids a second trip should the first pack be wrong.
Codes and phones confused with BA62
Short codes differ by one character, and print on old stickers fades. B, 8 and 6 can look alike, and so can 2 and Z. Hold the sticker under bright light before deciding it reads BA62.
- The nearby BA codes, such as BA61 and BA45, each have their own page. Read those instead of assuming a share.
- Redmi codes that look close, such as BN62, belong to the Xiaomi family and are a different pack. See the BN62 page.
- The 4G and 5G versions of one phone name can carry different batteries.

Failing battery: what to look for
| What the Y29 4G does | Why BA62 does it | Your move |
|---|---|---|
| Percentage drops fast even on light use | BA62 now stores far less | Test Y29 4G health, then plan for BA62 |
| Phone switches off at 25 or 30 percent | BA62 voltage dips under load | vivo service can measure BA62 |
| Y29 4G back or screen edge lifting | BA62 has swollen | Unplug the Y29 4G and go today |
| Phone is warm while idle | Heavy app, bad cable or a faulty pack | Restart the Y29 4G, remove its cover, test BA62 |
Fast drain often comes from apps, weak signal or a high refresh rate, so start with our drain page. If the habits are fine, try the battery health check.
Should BA62 bulge, heat, leak or dent, it becomes a fire hazard. Disconnect the Y29 4G immediately, keep it unflexed and away from heat. Take it to vivo service. Cheap BA62 copies often overstate capacity, so buy only a pack whose full code matches your old sticker.
Replacing a BA62 pack the safe way
The Y29 4G is sealed, so the swap is not a home job. vivo service or a well regarded local shop can do it with the right tools. Give them the Y29 4G model number and ask to compare the new BA62 with the old one before fitting.
How to spot a weak copy:
- The pack weighs visibly less than the one you removed.
- BA62 print is smeared without a batch line.
- It claims much more than 5500 mAh at the same size.
- The connector shape or the cable length is a little different.
Another 5500 mAh code may not fit the Y29 4G at all. Our fitting guide covers any phone.
Daily care for a large pack
A pack of this size lasts longer when it stays cool. Keep the Y29 4G away from pillows, beds and sunshine while it charges. Remove a thick cover if the Y29 4G's back warms.
Use the original charger and cable, or one with the same rating. Replace any Y29 4G cable that warms near the plug. Long hours at 100 percent also age BA62, so unplug the Y29 4G when convenient. If the Y29 4G still dies early after a full charge and restart, get BA62 tested before buying.
