Which Alkys should I keep around the house for remotes, flashlights to giveaway, etc? What ARE the NiOX Duracell PowerPix?
Thanks!

I usually have enough alks lying around that came with products that I just recycle those in handouts or non-critical apps like remotes.

Which Alkys should I keep around the house for remotes ...

The only alkaline I use these days is a 9volt in a Sony Cube alarm clock.

Everything else, including all low drain devices, are either running on Eneloops or a small selection of 1600-1700mAh Sanyo TwiCells circa 2002.

I just did a break-in charge on a pair of AAA Eneloops that have been in constant use in a wireless mouse for over 18 months, and they came in at 825mAh and 829mAh respectively.

It's noteworthy that they have always been run down to the point where the mouse quits working before they're charged.

With no capacity loss in over 18 months, and more importantly, no worries about leaks, I can't think of any advantage to using alkalines in the mouse, or in any other device for that matter ...

What ARE the NiOX Duracell PowerPix?

The Duracell FAQs on the PowerPix:

1. What is DURACELL® PowerPix?

Duracell ® PowerPix is a battery that is designed using NiOx Technology, based on nickel oxyhydroxide chemistry, that enables significantly better performance (up to 2 times more pictures*) in digital cameras than regular alkaline batteries. Duracell ® PowerPix, available in AA and AAA sizes, is the newest addition to the Duracell ® portfolio.

2. How does DURACELL® PowerPix provide better performance in digital cameras?

Duracell ® PowerPix chemistry and cell construction are designed to release more power to meet the needs of extremely high drain applications such as digital cameras.

3. What is the shelf life of DURACELL® PowerPix?

Similar to our alkaline batteries, Duracell ® offers a 7 year freshness guarantee for Duracell ® PowerPix.

4. What happens if a consumer installs a PowerPix battery in a device other than digital cameras?

While we recommend that Duracell ® PowerPix only be used in digital cameras:

The consumer will not see a performance advantage versus regular or premium alkaline in other devices.

Flashlights may burn brighter, and motors may run faster but for shorter durations than with alkaline because of the higher operating voltage of PowerPix.

5. Can the higher operating voltage of PowerPix cause damage in some devices?

No significant safety issues or device damage will occur if NiOOH is used in general purpose devices.

Most devices will operate just fine with PowerPix , but consumers will not see a performance advantage.

Flashlight bulbs may have shorter life due to higher brightness.

Motors in toys and appliances may run faster, hotter, or louder for a shorter duration.

6. Can DURACELL ® PowerPix be recharged?

No, Duracell ® PowerPix is a non-rechargeable primary battery. Like any other non-rechargeable primary battery, recharging Duracell ® PowerPix can have a negative impact on the battery safety and is strongly discouraged. Abuse of the battery, such as recharging, may result in leakage or explosion.

7.Can PowerPix be mixed with alkaline batteries in device?

No, because of their different chemistries they must not be mixed.
