The JK50 battery model name is a Motorola code that most listings tie to the Moto G9 Play and the Moto E7 Plus. Both Motorola phones ship with a 5000 mAh pack, the typical figure given for JK50. Motorola codes use two letters and two digits, so JK50 shares a style with PC60 and QF50, though each has its own phones.
People also search "jk 50 battery model name" or simply "moto jk50". JK50 is printed on the cell sticker, hidden under the back panel of the G9 Play and E7 Plus. Your own phone's model number, found under Settings and About phone, matters more than the Moto name, because Motorola sold several look-alike phones in the same period.
Quick facts
Step by step
Write down the model number of your phone
Open Settings, then About phone, and note the model number. If you cannot see it, type model in the Settings search bar.
Compare it with the phones in the table below
The G9 Play usually shows a number starting
XT2083, and the E7 Plus one startingXT2081. A different number means you should not assume JK50.Have the label read when the back is opened
A technician can lift the back and read
JK50on the pack sticker. Ask for a photo of it, front and close up.Match the new pack before it goes in
Put the new pack next to the old one. The code, the shape, the connector and the weight should all look the same.
Phones that use the JK50 battery model name
Motorola's letters do not name a phone, so JK50's phone list comes from parts records. Spare part listings for JK50 name the Moto G9 Play and the Moto E7 Plus together. They also quote the phone model numbers, which is the safest way to compare.
| Phone | Model number series | Note |
|---|---|---|
| Moto G9 Play | XT2083 | Listed with JK50, 5000 mAh class |
| Moto E7 Plus | XT2081 | Listed with JK50, 5000 mAh class |
| Moto G7 Power, Moto One Fusion, Moto G Play | Not confirmed here | Named in some listings, often with other codes; check the label |
The Moto G9 Play and the Moto E7 Plus are both listed with the same pack, which is why one code covers them. The last row is a warning, not a promise: names such as G7 Power, One Fusion and G Play appear in listings made for other countries, and the phones sold in India under similar names may use a different battery.
How much capacity a JK50 pack gives
Motorola quotes 5000 mAh typical for the G9 Play, the JK50 figure. Many battery labels also carry a rated (minimum) number that is a little lower. Your label may show that lower value, so take that as the true minimum for your own pack, not as a fault.
For JK50, watt hours are its 5000 mAh times the printed voltage, over a thousand. Listings often give JK50 as about 3.85 V, which makes 5000 mAh about 19.3 Wh. Do not compare two packs by mAh alone if their voltages differ.
What JK50's capacity means day to day depends on the phone. Screen size, chip, signal and brightness all matter. A light user may get a full day, while a heavy gamer, or someone in a weak signal area, will see a shorter day.
Confirm JK50 before you order a replacement
A wrong pack is the most common waste of money at the counter, and it is easy to avoid. Start from the phone, not from the code, because Motorola packs often look the same in a photo.
- Read the model number in About phone.
- Check that it belongs to one of the series in the table above.
- Ask for the old JK50 to be read once the back is off, and photograph the label.
- Order or accept only a pack that shows the same code, with a connector of the same shape.
If the label has gone faint, tilt it under a bright torch. On a rubbed JK50 sticker, J, K, 5 and 0 can be misread.

Motorola codes that get mistaken for JK50
Every Motorola pack has a code of the same shape, so one wrong letter or digit gives a different battery. Do not swap packs just because the capacity matches.
- PC60 and QF50 are different codes for different Motorola phones.
- NH50 ends in the same two digits as JK50, so it is easy to mix up in a hurry.
- MC50 also ends in 50. Read the first two letters first.
An owner of an E7 Plus brought a spare pack bought earlier for a friend's phone. Both packs said 5000 mAh, and both ended in 50. The first two letters were different, and the connector did not line up. The technician read the old sticker, saw JK50, and ordered the matching one.
Phones with similar names, such as the Moto G9 Power and the Moto G9 Plus, are also easy to confuse with the G9 Play. Their packs are not confirmed as JK50 here, so go by the label.
Signs that a JK50 pack is wearing out
| G9 Play symptom | Likely reason | What to do |
|---|---|---|
| G9 Play dies early, around a fifth charge | Worn JK50 cannot give peak current | Check E7 Plus health, then plan a JK50 |
| G9 Play lasts half a day or less | Lost capacity after long use | Check app usage on the E7 Plus, then test JK50 |
| Back panel lifts or the screen edge rises | JK50 has puffed up | Stop charging and go for repair that day |
| E7 Plus warm while idle | Worn JK50, or a stuck app | Restart the G9 Play, drop its cover, test JK50 |
Before you blame the pack, see the page on a battery that drains fast, because signal and apps explain many cases. Then the health check shows how far JK50 has aged.
Bulging, heat, leaks or dents make JK50 dangerous. Disconnect the G9 Play, let nothing press on the cell, and keep it clear of warmth. Lots of JK50 knock offs advertise far past 5000 mAh; only an exact code is acceptable.
Fitting a new pack safely
These phones usually have the pack fixed under a glued back. Opening them needs the right tools, heat control and care with the thin cables. Leave the job to Motorola service or a repair shop that you trust, and tell them the model number and JK50 together.
You can judge a copy JK50 before fitting:
- It is lighter than the JK50 you removed.
- JK50 print is smudged with no batch or date marks.
- It claims 6000 mAh or more in the same body, which a cell of that size cannot honestly hold.

Daily care for a 5000 mAh JK50 phone
Large packs in budget phones are often left on charge all night, which keeps the cell full and warm for hours. The G9 Play should charge on something cool and rigid, never tucked into bedding, with a bulky cover removed as soon as it warms.
Use the G9 Play's boxed 20 W TurboPower charger and cable, or a good unit at the same or lower wattage. Change a cable whose plug end looks scorched or loose. Speed of charging follows the adapter watts, so a 5000 mAh pack on a slow adapter can take a long evening. Should the E7 Plus keep cutting out at a healthy percentage after a reboot and full charge, test JK50.
