Alkaline surprise

[Niconical]

I found an old device, a cloths shaver.
It's a battery powered device which shaves lint off clothes.

hasn't been used for more years than I can remember.

The battery has been fitted in there the whole time.

It's a Duracell C-cell, "expired" in September 1996.

No leaking, 1.51v, still running!

I also have a Panasonic C-Cell expired 01/2000 still running in a clock I've never changed it since buying the clock in 96/97? and it's still going strong with no leakage.

I had a 2D flashlight and a 4D lantern by our back door that we used to use when we went camping.

They cells were very weak but no leaking. Jan 2002 expiry on them.

About a year ago my father mentioned to me that he believes companies put expiration dates on things just to get you to buy more.

Also as a liability waiver. If you keep using something beyond the expiry and something happens, the manufacturer is not liable for the damages.

I don't think the dates on the batteries are actually expiration dates. If you read the fine print around the date it states "Best if used by" or "Best if installed by". I believe it means they guarantee that it will be at it's peak performance if used by that date. Just my .02

If I remember correctly, the "use by" date indicates 80% capacity left by that time.

I don't know if it's all the heat and humidity down here on the Gulf Coast, or what, but if I leave alkalines in any device for more than a year or so, they leak.
Doesn't seem to matter what brand I use, they all leak.
Remote controls, lights, short wave radio, boom boxes, digital voltmeter.... all destroyed by leaking alkalines.

I'm not that lucky. My Duracell AA batteries leak on me several times already. I think they are worse than Energizer or Rayovac.
