Those old duracells that you could press on to see how much juice it had left?

[Caesis]

Whatever happened to them? Are they still being made?
Does anyone know what I'm talking about?

 

[Black Rose]

I know what you're talking about.

I took a set of D cells out of a lantern earlier this year that had those in them. They had a best used by date of 2002.

 

[Illum]

they used to have testers built into the cartons, then they built it onto batteries themselves, then energizer competed using the ones that lights up the "good sign" ...

Before then Duracells finished with the Duracell Ultra is when energizer came out with "Energizer advanced formula." Sometime when Duracells started making coppertops Energizer updated their E2 series and from that point on those cells with a builtin bar disappeared completely. Now you can't even find cartons that had the testers:mecry:

I knew I should have saved those things:shakehead

I remember I had some cells from many years back. I never knew how to use them at the time...

 

[jchoo]

Hmm... pretty sure I still have some of these lying around... and they'll probably still fire up my X1.

Energizer E2 Titanium technology, I've bought them about 4-5 years ago.
Have 2 left (Exp. 2009), still work fine, but the "strip" never worked right since day 1.

The strips were:
Inaccurate.
Relatively expensive.
A cause of self discharge unless perfectly applied.

All reasons why the were discontinued.

Years ago I took one of those batteries apart to get to that built in test strip. I used a power supply set at 1.5v and connected it to the test strip. The test strip got pretty warm. Seemed to me that what it did best was just run the battery down quicker so that you had to buy new ones, etc, etc. :shakehead

Depends on room temperature, also on the temperature of your fingers.
