Does your battery perform well in one appliance, but not last very long in another one?
Then try Duracell Ultra!
It is specifically designed to be the longest lasting Duracell alkaline battery in all devices, and contains new and improved HPC (High Performance Cathode) technology. Every Duracell Ultra battery has a Powercheck Tester, so you always know how much energy is left inside.
*based on the average of testing for devices used most! FAQs 1. Have all the alkaline batteries in the Duracell portfolio been upgraded?
All of the alkaline batteries in the Duracell portfolio in AA and AAA have been upgraded. 2. Which is the best alkaline battery for performance in the portfolio?
Duracell Ultra is the Best Ever Duracell alkaline battery across all devices. No other alkaline battery lasts longer than Duracell Ultra, based on the average of testing for devices used most. 3. How has Duracell Ultra been improved?
Duracell has employed a new HPC High Performance Cathode, with new superconductive graphite and ultra pure and higher active MnO2 (active ingredient) in the new Duracell Ultra, ensuring the best ever performance from its batteries. Duracell Plus technology has also been improved for advanced longer life. Using new SCG Super Conductive Graphite, with smaller particles and higher conductivity, it enables the use of less graphite. This allows for more MnO2 (active ingredient), which now means that this reliable energy source lasts even longer than before. 4. Does the new and improved Duracell Ultra still have the Power Check facility on all cells?
Yes. 5. Which Duracell batteries are best for my everyday devices e.g. remote control, digital camera, MP3 player and motorised toys?
Duracell Ultra is the best alkaline battery across all devices. 6. Can I mix new batteries with old batteries in my device?
No, do not mix old and new batteries. 7. Can I mix batteries with different capacities in my device?
No, batteries of matching capacities should be used within your device. 8. How does Duracell Ultra differ to Duracell Plus?
Ultra is the BEST DURACELL battery across all devices. No other alkaline battery lasts longer than Duracell Ultra, based on the average of testing for devices used most. 9. Does the new formulation for AA / AAA alkaline products influence the environmental sustainability?
The formulation does not change the environmental sustainability of these batteries since they will continue to be made primarily from the common metals steel, zinc and manganese, all of which are recyclable metals. When the batteries become waste Duracell will pay for them to be collected and recycled as required by the new EU Battery Directive. In order to minimise the impacts on the environment from waste batteries Duracell recommends that consumers dispose of their used batteries within the battery collection system in their country. 10. What are the anode, cathode and electrolyte?
These are the basic components of a battery and like other alkaline batteries are: The anode is the negative electrode and is made of zinc. The cathode is the positive electrode and is made of manganese dioxide. The electrolyte is an aqueous solution that allows transport of ions between the electrodes and is made of potassium hydroxide. 11. What is their life expectancy for best performance?
Duracell has a freshness guarantee of 7 years and guarantees performance during that time. As there are thousands of various devices and usage there is no one performance life expectancy that is given.
