DEJI CK Battery: The Refurbisher’s Choice for a Stable, Clean, Like-New iPhone Experience

Why Refurbishers Worldwide Are Choosing DEJI CK Decode Batteries

In the refurbished iPhone business, battery choice matters more than most people think.
It affects how the phone looks in iOS, how it performs, and how easy it is to sell.

That’s why more refurbishers are switching to DEJI CK Series batteries.

Looks Clean in iOS

After installation:

* Battery health shows normally
* No “Unknown Part” message
* Battery info looks the same as original

Also, there is no repair record showing in the system.

For refurbished phones, this is important.
No warnings, no extra messages — just a clean device that’s easier to sell.

The result is a clean iOS interface that feels close to a factory-installed battery.

Better Margin

Original batteries are expensive.
CK batteries cost less and give you more room to work with pricing.

You still get stable performance, but with better profit.

For most refurbishers, that’s the key point.

DEJI CK Decode Batteries VS Battery Cell Transplantation

Problems with Cell Transplantation

Some people still use cell transplantation, but it has a few common issues.

Item	Description	Impact
Welding Complexity	Requires PCB grinding and precision spot welding	High technical difficulty, depends on skilled technicians
Welding Risk	Nickel layer must be cleaned or directly welded	High risk of cold solder joints or circuit damage
PCB Aging Issue	Uses original used PCB board	Aging components increase internal resistance
Battery Drain	Unstable pairing between old PCB + new cells	Faster power loss, reduced battery life
Performance Degradation	Based on reused control board	Gradual decline in user experience over time
Non-Repeatable Process	PCB continues aging after reuse	Cannot be reliably reused multiple times
⚠️ Quality Inconsistency	Highly dependent on manual workmanship	Difficult to maintain mass production consistency
After-sales Risk	Instability leads to higher failure rate	Increased warranty and service cost

How CK Battery Is Different!

Deji CK battery works in a simpler way.

It connects and reads the original data, without putting the same stress on the PCB.

That helps with:

* Stability
* Lower risk
* More consistent performance

After 1–2 years, you can replace the battery again, and the PCB can still be used.

In Short

* Looks like original in iOS
* No warning messages
* Stable to use
* Better margin
* Less risk than transplantation

For refurbishers who want fewer problems and better profit,
CK battery is a practical option.

Deji also offers plug-and-play diagnostic decode batteries for your selection.
