Pickle Power AAAA Batteries, 4 Pack 500mAh Rechargeable AAAA Ni-MH Batteries with Charger for Surface Pen Active Stylus
Quick take
This AAAA rechargeable battery kit includes four 500mAh Ni-MH AAAA cells plus a 4-slot smart charger with an LCD status display. It is best for buyers who need AAAA rechargeable power for compatible devices, especially if you want to charge multiple batteries at once. The main caveat is that, while the batteries appear to perform as expected, there is limited evidence around long-term charger durability.
Pros and cons
Pros
- Includes 4 rechargeable AAAA Ni-MH batteries (500mAh) plus a dedicated smart 4-slot charger.
- Smart charger uses LCD icons to show each battery’s charging status.
- Designed for “charge 1 to 4” at a time, which reduces waiting if you have multiple cells.
- Rechargeable Ni-MH cells are marketed for up to 1200 recharging cycles.
Cons
- Buyer feedback includes at least one report of charger failure after a short period, even though the batteries worked.
- Capacity (500mAh) may not be as strong as higher-capacity alternatives for power-hungry devices.
- Best fit depends on your device being compatible with AAAA rechargeable Ni-MH batteries (some devices use different chemistry or sizes).
What buyers think
Buyer-review evidence is limited, but the available snippets point to a consistent theme: these batteries are generally working well for AAAA devices and are described as lasting a long time in that use case. Multiple reviews also highlight the convenience of charging and the ability to charge batteries together in the included charger. On the downside, the evidence includes a charger reliability concern where the charger stopped working after very few uses, which is relevant if you rely on recharging frequently. Overall sentiment is leaning positive, but the charger durability proof is not strong enough to guarantee long service life based on review volume alone.
Key features that matter for AAAA rechargeables
Charging convenience with a 4-slot smart charger
The kit is built around the charger, with four independent slots and an LCD display intended to show each battery’s status. In practical terms, this supports batch charging (charging multiple batteries at once) and makes it easier to see when cells are fully charged versus still charging.
Ni-MH AAAA cells rated at 500mAh
The included AAAA batteries use Ni-MH chemistry, with a stated capacity of 500mAh and a battery voltage listed for the chemistry. Rechargeable capacity matters most for buyers who use AAAA devices regularly and want fewer battery swaps over time.
Recharge cycle life (marketing spec)
The batteries are marketed as rechargeable up to 1200 cycles. That spec can help you estimate whether a rechargeable kit makes sense for your routine, especially compared to frequently buying disposable alkalines.
Flexible charging input options
The charger is described as supporting charging via a USB Type-C port and a micro USB port. That matters if you want to recharge from a laptop, power bank, wall charger, or car charger without needing a specific AC adapter.
Safety and fault detection design
For buyers who care about charging safeguards, the charger is described with protections such as MCU control, over-heat and over-current protection, short-circuit protection, and detection for non-rechargeable or defective batteries. These features are relevant when you are inserting batteries quickly or reusing batteries across different devices.
Who this kit is for
- Owners of AAAA-compatible devices (including small electronics and stylus-related setups that specifically call for AAAA rechargeable cells).
- Buyers who want fewer battery runs and prefer recharging over buying disposables.
- People with multiple AAAA batteries to rotate, since the charger supports charging up to four batteries at once and includes per-slot status indication.
Who should look elsewhere
- Device compatibility is unclear. If your device requires a different battery chemistry, voltage behavior, or size, double-check before switching.
- You are very sensitive to charger reliability. While batteries appear to perform well, the available review evidence includes a charger that failed after a small number of uses.
- You need higher sustained capacity than 500mAh for frequent or power-hungry operation. In that case, you may want to compare higher-capacity AAAA rechargeables (while still matching Ni-MH and charger compatibility).
Pros and cons recap
Buy this if you need a complete AAAA rechargeable battery and charger kit, you want the convenience of charging multiple cells with clear status icons, and your device is compatible with AAAA Ni-MH rechargeables. Consider alternatives if your priority is maximum charger longevity, or if you have special battery compatibility requirements beyond standard AAAA Ni-MH.

FAQ
Are these batteries compatible with Surface Pen or other stylus devices?
The kit is designed for devices that use AAAA rechargeable batteries and is marketed for use with Surface Pen active stylus situations that call for AAAA rechargeable cells. Still, confirm your specific stylus model’s battery requirements before purchasing.
Can the charger charge one battery at a time?
Yes, the charger is described as able to charge between 1 and 4 batteries, depending on what you insert.
What does the LCD display show?
The LCD is intended to indicate the charging status for each inserted battery, including a flashing icon during charging and a solid icon when fully charged.
How are these batteries charged, and can I use a power bank?
The charger supports multiple USB input options (Type-C and micro USB), which is intended to let you recharge from devices like a laptop or power bank, along with standard wall or car chargers.
What is the battery capacity and how long might they last?
The batteries are rated at 500mAh. Real-world runtime depends heavily on the device’s power draw and usage patterns, but the available buyer snippets generally describe good longevity in AAAA devices.
Is the charger reliable?
Most visible feedback is positive about the batteries and the charging setup, but there is limited evidence that at least one charger stopped working after very few uses. If charger uptime is critical for you, consider comparing other kits with stronger charger reliability signals.
What batteries are included?
The package includes four AAAA Ni-MH rechargeable batteries and one smart AAAA battery charger.
Bottom line
Pickle Power’s AAAA rechargeable kit is a solid option for AAAA device owners who want an easy recharging setup, per-slot LCD status, and batch charging. The clearest reason to think twice is that charger durability proof is not rock-solid in the available review evidence, even though the batteries themselves appear to work as intended.
