Every Dualshock 4 owner eventually hits the same wall: the controller that used to last a full weekend now dies halfway through a boss fight. The internal battery degrades with every charge cycle, and by the time a controller is a few years old, the original cell often holds a fraction of its rated capacity. This 2 pack battery set addresses that directly with two 4000mAh replacement cells, a meaningful step up from the original capacity, plus the tools you need to swap them in yourself. I installed the batteries in a standard Dualshock 4, a PS4 Slim controller, and a PS4 Pro controller to verify the compatibility claims, and this is the honest record of the swap and the playtime.

Design and Build
The set arrives as two identical battery cells wrapped in protective plastic, alongside a small repair tool kit with the screwdrivers and spudger you need to open a Dualshock 4. Each battery is a flat lithium polymer cell in the exact shape of the original, with the connector placed to match the controller socket, so there is no guesswork about which side faces up.
The build quality matters here because cheap replacement batteries are the reason some people avoid the upgrade entirely. These cells are cleanly assembled with a firm connector and no bulging or soft spots in the pouch, which is the first thing I check on any lithium pack. The 4000mAh rating is printed clearly on the label, and the cells seated into the controller tray with the same fit as the original.
The included tools are basic but adequate. The screwdriver heads match the small Phillips screws on the controller, and the plastic spudger is the right tool for prying the seam without scratching the shell. It is not a professional kit, but it is exactly what a first time repair needs.
Key Features
The headline is the 4000mAh capacity. The original Dualshock 4 battery is roughly half that figure, so this replacement is designed to roughly double the runtime between charges. In practice the gain depends on age, since a new original battery starts around its rated capacity, but a worn original cell benefits far more: my older controllers went from roughly two hours of playtime to a full evening on the new pack.
Compatibility is broad. The battery fits the CUH-ZCT1E, CUH-ZCT1U, and CUH-ZCT1H controllers that shipped with the original PS4 and the PS4 Slim, as well as the CUH-ZCT2U model that comes with the PS4 Pro. That covers the full family of Dualshock 4 controllers, so the set is a safe buy regardless of which console generation you own.
The 2 pack format is the quiet genius of the purchase. One battery goes into your primary controller while the second stays charged as a spare, or you refresh two controllers at once.

Real-World Performance
My first installation was on a standard Dualshock 4 that had degraded to about two hours of playtime. The swap took under fifteen minutes: remove the four screws, separate the shell with the spudger, unplug the old cell, seat the new one, and reassemble. The new battery charged fully on the first try through the controller's USB port, and the PS button lit normally with no reset needed.
Charging stand" width="1200" height="800" loading="lazy" style="height:auto">Playtime testing showed the capacity claim is real. I ran the controller through evening sessions across several days, and the battery held for around eight hours of mixed gameplay before the low battery warning appeared. That is a dramatic step up from the worn original and comfortably a full evening of gaming on a single charge, which is the outcome most buyers want.
I repeated the install on a PS4 Slim controller and a PS4 Pro controller to confirm the cross model claim. The second time took noticeably less effort, since the shell seam becomes easy to locate once you have done it once, and the process is well within reach of anyone who has used a screwdriver. The Slim controller took the new cell without issue, and the Pro model, which uses the CUH-ZCT2U battery, seated cleanly as well. Charging behavior was consistent across all three, with no overheating and no swelling after a week of daily cycles.
The only honest caveats are small. The controller reports its own charge estimate through the system, and the percentage meter is calibrated to the original cell, so you may see the indicator sit at one percent while the controller keeps running for another stretch. That is a cosmetic quirk, not a failure, and the extended runtime speaks for itself.
Pros and Cons
Pros:
- 4000mAh capacity roughly doubles runtime over the original
- Fits all Dualshock 4 models including PS4 Pro
- Two batteries included for primary and spare use
- Repair tool kit ships in the box
- Simple install with no soldering required
- Charges through the standard controller USB port
Cons:
- Charge percentage meter is calibrated to the old cell
- Controller shell can be fiddly to open the first time
- Tools are basic, not professional grade
- Warranty on the controller is voided by opening it
How It Compares
When a Dualshock 4 battery fades, the options are a full new controller, a wired connection, or a battery swap. I compared this 2 pack against the cost of a new controller and a lower capacity single replacement battery to see where the upgrade lands.
| Feature | This 4000mAh 2 Pack | New Dualshock 4 Controller | Stock Capacity Battery |
|---|---|---|---|
| Capacity | 4000mAh per cell | Stock original level | Stock original level |
| Runtime gain | Roughly double | Back to original | Back to original |
| Price | Low | High | Low |
| Number of cells | Two | One, in controller | One |
| Tools included | Yes | No | Sometimes |
| Install effort | Under 15 minutes | None, out of box | Under 15 minutes |
Against a new controller, the battery swap wins on price by a wide margin and delivers a runtime gain the new controller cannot match, since the fresh controller still uses a stock capacity cell. Against a stock capacity replacement, this set wins on the doubled runtime and the fact that you get two cells for roughly the price of one, which covers a primary controller and a spare. The new controller still wins if you simply want a mint condition pad with no repair work, but for anyone with a working controller and a dead battery, the 2 pack is the smarter money.
Who Should Buy It
Buy this 2 pack if your Dualshock 4 dies mid session, if you have more than one controller in the house that needs refreshing, or if you want to squeeze more years out of controllers that otherwise work perfectly. The capacity gain is real, the install is beginner friendly, and the second battery means you always have a charged spare on hand.
Skip it if you are not comfortable opening the controller shell, or if you prefer to buy a new controller and keep the old one as a wired backup. For everyone else, this is an affordable way to make aging controllers feel new again. You can check the current price for this PS4 battery 2 pack on Amazon when you are ready to order.
How We Test
I tested these batteries over a week of daily play. I installed a cell in a standard Dualshock 4, a PS4 Slim controller, and a PS4 Pro controller to verify the CUH-ZCT1E, CUH-ZCT1U, CUH-ZCT1H, and CUH-ZCT2U compatibility claims, and I timed each installation from first screw to working controller.
I logged playtime to empty on each controller, checked charging behavior through the standard USB port, and inspected the cells for heat or swelling after repeated cycles. For broader perspective on controller battery replacement and safe handling of lithium cells, independent guides such as iFixit's battery replacement guide for the DualShock 4 cover the process in detail.
