Rechargeable D batteries that promise high-capacity, USB-C recharging for torches, radios and other D-cell devices. The EEMB Rechargeable D Batteries deliver steady 1.5V output and reusable convenience for weekend trips and regular household use. Are these rechargeable cells a practical, eco-friendlier swap for disposable alkalines?
⚡ At a Glance
- • Capacity: 5550mWh per cell with near-constant 1.5V output until depletion
- • Best for: Large torches, radio receivers and transmitters that need long-running D cells
- • Not ideal for: Devices that specifically require non-rechargeable alkaline D cells
High-capacity lithium-ion D cells recharge via USB Type-C and include a 4-in-1 charging cable. Integrated safety circuitry manages charging and prevents overcharge and reverse charging.
Long runtime – thanks to 5550mWh high-capacity cells
Each cell stores 5550mWh and maintains a steady 1.5V output until the charge is exhausted, matching the voltage of standard D cells. Lithium-ion chemistry delivers consistent voltage under load compared with many rechargeable alternatives.
Extended operating time keeps torches and radios running longer between charges, useful for camping or emergency kits. Fewer battery swaps are needed during prolonged use.
Fast, convenient recharging – with 4-in-1 USB Type-C cable
A supplied 4-in-1 USB charging cable accepts standard USB power sources and can charge four cells simultaneously, with a typical full charge time around 1.5 hours. Automatic stop occurs when charging completes.
Quick recharge from a single USB port reduces downtime and removes the need for separate battery chargers. Suitable for charging on the go from power banks or car chargers.
Safe and durable cycling – thanks to integrated protection and long cycle life
Built-in integrated safety circuitry monitors the charging process to prevent overcharging, over-voltage, over-current, over-discharge and reverse charging. Cells are specified for 1000+ recharge cycles and contain no mercury, cadmium or lead.
Confident, low-maintenance use with reduced risk of charging faults, and the long cycle life cuts household battery waste significantly. Environmentally friendlier option compared with many single-use alkalines.
✨ The 4 Key Reasons for EEMB Rechargeable D Batteries
- USB Type-C cable included – Charge four cells at once from a single USB port
- ~1.5-hour full charge – Get back to use quickly after depletion
- Integrated safety circuit – Protects against overcharge, over-voltage and reverse charging
- Rechargeable 1000+ times – Dramatically reduces single-use battery waste over the long term

❓ Frequently Asked Questions
Q: Are these batteries compatible with devices that use standard D cells?
A: Yes. The cells match the regular D cell 1.5V form factor and nominal voltage, so they fit and can be used in the same devices listed as compatible.
Q: How do I recharge the batteries and how long does charging take?
A: A 4-in-1 USB Type-C cable is included, allowing simultaneous charging of four cells from a USB port; a full charge typically takes around 1.5 hours.
Q: Are the batteries safe and long-lasting?
A: Built-in integrated safety circuitry prevents overcharging, over-voltage, over-current, over-discharge and reverse charging, and cells are rated for 1000+ recharge cycles.
🏆 Our Verdict
Ideal for anyone who uses high-drain D-cell devices regularly, such as campers, hobbyists and households with emergency torches. The combination of 5550mWh capacity, USB Type-C recharging and comprehensive safety protection makes these cells a practical, reusable alternative to disposables. While initial purchase replaces multiple single-use packs, the long cycle life and reduced waste deliver clear long-term value.
