The Oppo A17 battery model is BLP915 according to most listings, and the A17k carries the same code. Adverts quote the capacity as 5000 mAh typical for a Li-ion polymer cell. The letters BLP only tell you the maker family, never one phone, so use the phone table further down.
Many people type "a17k battery model" or "a17 battery model number". Both are budget phones from one series, and listings give them a single shared pack. No maker parts sheet backs this up yet, so treat it as a strong pointer only. Have the label of the battery being replaced read out before any order is placed.
Quick facts
Step by step
Write down the phone name and model number
Open Settings and type model in the search bar, or look at About device. Keep the box if you still have it, because the model number is printed there too.
Tell the technician which letters follow A17
Say clearly whether the phone is the A17 or the A17k. Listings give both the same pack, but the box and the number decide the matter if your phone is a regional version.
Have the old label read, not guessed
With the back opened by the technician, look for
BLP915printed beside the capacity. Take a photo of it for later.Compare the new pack with the old one
Put them side by side: same code, same outline, same connector, and a similar weight. Refuse a pack that fails any one of these.
A17 or A17k: why the small letter matters at the counter
The A17k is not a typing slip for the A17. It is a separate phone with its own model number. When a customer asks for an "A17 battery", a shop may check only the first three characters and hand over whatever is on the shelf. Here both phones point to BLP915, so the risk is low, but the same habit goes wrong with other pairs of phones.
Read the name printed on the box, or the model number in About device, and say it in full. If your phone is a different version from the usual Indian one, a technician should still read the old label first.
A student came in with an A17k that ran flat before lunch. At first the shop suggested a pack built for the older A16, as its size was nearly the same. The technician refused to judge by size. After reading BLP915 off the original cell, the shop ordered only BLP915.
Rated and typical capacity of the A17 and A17k pack
Think of 5000 mAh as the headline number: it is what adverts and parts listings print. Many Oppo packs show a slightly lower minimum (rated) value on the label. That minimum for BLP915 has not been confirmed, so read your own label rather than a seller's description.
To turn mAh into watt hours you need the cell voltage, which is printed on the label. This page quotes no voltage because none is confirmed. Two packs with equal mAh but unequal voltage ratings hold slightly different energy, so never compare by mAh alone.
On a budget phone, 5000 mAh usually carries a day of mixed use. Your result will depend on mobile signal, screen brightness and which apps stay open. A full charge also takes a good while on a low-watt charger.
Where to read the A17k battery model name before you pay
The code is printed on the cell label and nowhere on the outside of the phone. Settings will show you the phone name and model number, and some versions show battery health or capacity, but menu titles differ between software releases. If you cannot find the page, use the search field at the top of Settings and try the word battery.
- On the battery: the label carries BLP915 next to the capacity. The phone is sealed, so a technician must open the back.
- On the box: the label shows the model number, which is the safest way to separate the A17 from the A17k.
- In a spare listing: the code should be written in full. Walk away from listings that say only "for Oppo A series".
The general method for any phone is explained on the page about finding the code of any battery.
Signs your A17 pack is ageing
| What you notice | Probable cause | Next move |
|---|---|---|
| Percentage falls steeply once past the halfway mark | Cell has lost real capacity | Run a health check, then compare with the label |
| Phone dies while the screen still shows charge | Aged cell cannot hold voltage under demand | Have a technician check the battery for you |
| Back panel gaps or screen lifts | BLP915 has puffed up | Stop charging and book a visit at once |
| Warm even when unused | A busy background app or worn BLP915 | Reboot, take off the cover, then watch again |
Before you blame the pack, rule out heavy apps and weak signal with why a phone battery drains fast. After that, the battery health check steps help you decide on a swap.
There is a real danger of fire when a cell swells, gets extremely warm to touch, seeps liquid, or shows a dent. Unplug the A17 straight away. Do not press or prick the cell. Rest the A17 in a cool corner. Get the A17 to a service desk that same day. Shops and websites are full of BLP915 copies claiming extra capacity, so only accept one whose code matches the print on your A17's old cell.
Fitting a new BLP915 pack and caring for it
The A17 and A17k are sealed phones. Have the pack changed at an Oppo service centre or at a shop you already trust. Give the technician the model number and request a side-by-side check of BLP915 against the old label.
A weak copy usually shows itself when you hold it:
- Its weight seems clearly less than that of the battery you removed.
- The printing is smudged and no batch details appear.
- The label claims far more than 5000 mAh, and a cell this small cannot really give that much.
You can find a fuller list on our mobile battery replacement guide.
After the swap, charge once to full with the original charger and note how many hours the phone lasts on a normal day. That gives you a baseline for later.
To look after the battery daily, do not charge in a warm room or beneath a pillow. Try not to keep the phone plugged in at full charge through the whole night. Nothing wears out a cell quicker than heat.
Frequently asked questions
What is the Oppo A17 battery model name?
Many online listings give BLP915 as the battery code for the A17. They also list its usual capacity as 5000 mAh. Do not just trust this. Open the phone back or check your current cell, and read the code printed on it.
Does the Oppo A17k use the same oppo a17 battery model as the A17?
Listings give both phones the same code, BLP915. Because the two are separate phones, check the model number on your box before ordering.
What capacity is the A17's BLP915?
Ads usually mention 5000 mAh as the normal rating. The lowest value written on the cell can be slightly under that. To find the true figure, check the print on the cell of your own phone.
Can I fit an Oppo A16 battery in an A17k?
Do not assume so. The A16 has its own code page, and a pack of equal size with another code could fail to connect.
Can I change the A17 battery myself?
The phone is sealed, so the back has to be opened with care and the pack lifted out safely. It is better left to a technician, because a careless move can puncture the cell.
How can I tell a fake A17 battery?
Watch for light weight, fuzzy printing, absent batch details, and a rated capacity much higher than 5000 mAh. Set it beside your old battery and see.
