Experience ultimate convenience with the R7 1.5V D Size 15000mWh Rechargeable Li-ion Battery. Featuring a built-in USB Type-C port, you can ditch your bulky external chargers and charge this battery anywhere using a standard USB-C cable (laptop, power bank, wall outlet, car charger).
Engineered with an advanced 1.5V constant voltage system, this battery provides stable power from 100% down to 0% capacity. Unlike standard NiMH rechargeables that drop to 1.2V quickly, the R7 ensures your gas stove igniters, water heaters, and high-drain flashlights work flawlessly until the very end.
With its Button Top design, it's 100% compatible with traditional D-size battery compartments found in most household devices. Enjoy a super quick 2-hour fast charge, an impressive 15000mWh capacity, and an eco-friendly 1000+ cycle life. One R7 battery replaces over 1,000 single-use disposable batteries! Available in 1, 2, and 4-pack sets, complete with a free storage case and charging cable.
Built-in USB Type-C Port: Plug and charge directly via any standard USB-C cable. No extra charger needed. Fully charged in just 2 hours.
1.5V Constant Voltage Output: Prevents device malfunction caused by voltage drops. Provides steady 1.5V power throughout the entire discharge cycle.
Button Top Design: Features a protruding positive terminal, ensuring perfect compatibility with standard D-size (LR20) battery compartments in flashlights, radios, and kitchen appliances.
15000mWh Ultra-High Capacity: Massive energy density that keeps your devices running longer than standard alkaline batteries.
1000+ Long Cycle Life & Smart Protection: Can be recharged over 1,000 times. Built-in intelligent BMS chip provides multi-layer protection against overcharge, overheat, overvoltage, and short circuits.

Q1: Why is the 1.5V constant voltage so important?
A1: Standard NiMH rechargeable batteries drop from 1.5V to 1.2V as they discharge. Many high-drain devices like gas water heaters and stoves will stop working or fail to ignite once the voltage falls below 1.3V. Our R7 battery provides a constant 1.5V until the very end, ensuring your device works perfectly with the last drop of energy.
Q2: What is the difference between Button Top and Flat Top?
A2: The R7 battery is a Button Top, meaning it has a protruding "nub" on the positive end. This is the standard shape for most household devices requiring D batteries, such as flashlights, radios, and toy cars. It ensures secure contact within the battery compartment.
Q3: How do I charge this battery?
A3: Simply plug a standard USB Type-C cable (charging cable is included in the box) into the battery's built-in port. Connect the other end to any USB power source (phone charger, power bank, laptop, or car charger). A green LED light will flash while charging and stay solid when fully charged (about 2 hours).
Q4: Will this fit in my standard D-size device?
A4: Absolutely. The R7 battery measures 32mm in diameter and 60mm in height, which matches the standard physical dimensions of a standard D (LR20) battery.
Q5: How can I tell when it's fully charged?
A5: The battery has a built-in LED indicator near the USB port. When charging, the light will flash green. When the battery is fully charged (approximately 2 hours), the green light will stay solid and bright.
