CTYOUNG Rechargeable D Batteries 1.5 Volt 4 Packs with Universal Battery Charger
Quick take
This 4-pack of rechargeable D cells is designed for devices that expect D-size batteries, pairing with a Type-C universal charger that can handle multiple rechargeable chemistries. It targets high-drain uses like lanterns, flashlights, and radios, with an emphasis on stable 1.5V output and fast charging options. The main buy caveat: it is intended for specific battery formats (1.5V lithium-ion and 1.2V NiMH/NiCd) and needs the right fit for your device battery holder.
Pros and cons
Pros
- Stable 1.5V output is intended for better performance in D-cell devices that are sensitive to voltage drops.
- Includes a universal Type-C charger (4 slots) intended to work across AA/AAA/C/D styles and supported chemistries (USB lithium-ion 1.5V, NiMH/NiCd 1.2V).
- Fast-charging option is available (with separate time expectations by battery size).
- Charging protections include over-charge, over-current, over-voltage, and short-circuit protection.
Cons
- Charging time varies notably by size, with D-cells taking longer than AA/AAA.
- Compatibility is limited to the supported rechargeable battery types, so it may not be ideal if you primarily use alkaline disposables or other specialized formats.
- Buyer-review evidence about long-term runtime is still limited because some users report short ownership windows.
What buyers think
Buyer feedback is generally positive and focused on practical setup and day-to-day performance. Several buyers describe the batteries as working well as replacements in real devices (for example, lanterns) and note that they charge quickly and hold up during storage or limited-use periods. A few comments also emphasize usability, with the charger described as straightforward to operate. Overall, the review evidence supports the idea that the set is easy to use and performs as expected for replacement needs, but longer-term capacity trends are not fully proven due to relatively limited time reported by some reviewers.
Key features and specs that matter
1.5V rechargeable D cells with high capacity focus
These are rechargeable D-size cells designed around a stable 1.5V output, with a capacity claim of 11000mWh per the set. That combination is aimed at devices that can lose performance when voltage sags, such as high-drain electronics like flashlights and similar household tools.
A universal Type-C charger for common rechargeable formats
The included charger uses Type-C input and supports charging for household rechargeable battery types in multiple sizes. It is positioned for both 1.5V lithium-ion (USB lithium-ion style, including AA/AAA/C/D) and 1.2V NiMH/NiCd (AA/AAA/C/D). It uses 4 slots, so you can charge a full set of the included D batteries at once.
Charging time expectations (by size)
Charging times vary by battery size, and there is also a fast-charging button. General expectations listed for charging include:
- Standard charging: AA about 1–2 hours, AAA about 1–2 hours, C about 3–4 hours, D about 6–7 hours.
- Fast charging: AA within about 1 hour, AAA within about 1 hour, C about 2 hours, D about 3 hours.
If you are planning around quick turnaround for D-cell devices, the fast-charge mode is the lever to pay attention to, since D-cells take significantly longer than smaller sizes.
Safety and alerts
The charger is described with multiple safety protections, including over-charge, over-current, over-voltage, and short-circuit protection. A flashing red LED alert is mentioned for incorrect battery placement, which can be useful when you have mixed battery types or you are reloading the slots quickly.
Pros and cons of this charger-battery kit
Who it’s best for
- Households that use D-cell devices (lanterns, flashlights, radios) and want to reduce disposable battery waste.
- Buyers who want one charger that can handle multiple rechargeable chemistries and common battery sizes (AA/AAA/C/D) rather than buying separate chargers.
- People who want a fast-charge option for when you need power sooner, especially for larger cells like D.
Who should avoid it
- If your device uses a battery format that is not compatible with D-size rechargeable cells, you will need a different battery size or type.
- If you only ever use standard alkaline disposables and do not want to commit to rechargeable cells, the value of a rechargeable kit will be harder to justify.
- If you need consistently fast charging for D-cells but your workflow requires repeated same-day cycles, verify your usage schedule around the stated D-cell charging times.
Is it worth it?
This set is most compelling when you want both the batteries and a charger system that can grow with your household battery needs. The main reasons to consider it are the stable 1.5V design for D-cell devices, the included 4-slot Type-C charger that can support multiple rechargeable battery types and sizes, and the availability of fast-charging mode. The biggest tradeoff is timing, D-cells generally require more charging time than smaller sizes. If your devices mostly run on D-cells and you have a mix of rechargeable batteries, it can be a practical one-system solution.

FAQ
Are these D batteries the same as standard D cells?
They are rechargeable D-size batteries intended for devices that use D-cell holders. As with any rechargeable system, ensure your device’s battery compartment is designed to accept D-size batteries and that the device tolerates the rechargeable output type.
What batteries can this universal charger charge?
The charger is described as supporting 1.5V USB lithium-ion batteries (AA/AAA/C/D) and 1.2V NiMH/NiCd batteries (AA/AAA/C/D), using Type-C input and a 4-slot charging layout.
How long does it take to charge D cells?
Charging times vary. The set lists standard charging for D-cells at about 6 to 7 hours, and fast charging at about 3 hours.
Is fast charging safe?
The charger includes safety protections such as over-charge, over-current, over-voltage, and short-circuit protection, and it uses an LED alert for incorrect placement.
How long do the batteries last on a charge?
Long-term runtime depends on your device’s power draw and usage pattern. Review evidence supports good day-to-day performance and reasonable holding power during storage for seldom-used devices, but long-term capacity consistency is not fully established in the available feedback.
Can I use the charger with batteries other than these CTYOUNG cells?
The charger is designed around common rechargeable chemistries and sizes it supports (1.5V USB lithium-ion and 1.2V NiMH/NiCd, in AA/AAA/C/D formats). If your batteries match those categories and sizes, they are more likely to be compatible.
