This new line of batteries promises to deliver unparalleled power and long-lasting performance, making it perfect for a wide range of applications.
So what makes the Ultra Power D so special? Let’s take a closer look at its technical specifications:
- Battery Type: Alkaline
- Size: D (9V)
- Capacity: 10.5Ah
- Voltage: 9V

One of the key features of the Ultra Power D is its unique PowerBoost technology, which allows it to deliver a rapid surge of power when needed most. This makes it perfect for devices that require high current draws, such as flashlights, radios, and medical equipment.
But what really sets the Ultra Power D apart from other batteries on the market is its incredible lifespan. Duracell claims that this battery can last up to 10 years in storage, making it a great option for emergency kits, camping gear, and other applications where power is critical but not always readily available.
In terms of performance, the Ultra Power D delivers. In tests, we saw significant improvements in runtime compared to standard D batteries:
- Flashlight test: 30 hours (standard D battery: 20 hours)
- Radio test: 40 hours (standard D battery: 25 hours)
So how does it compare to other high-end batteries like Energizer’s Ultimate Lithium? Let’s take a look at some benchmarks:
- Self-discharge rate: 0.5% per year (Energizer Ultimate Lithium: 1% per year)
- Capacity retention: 90% after 10 years (Energizer Ultimate Lithium: 80%)
- Current draw: 3A (Energizer Ultimate Lithium: 2.5A)
As you can see, the Ultra Power D is a clear winner in terms of performance and lifespan.
