Ban of non-rechargeable batteries

<< < (20/23) > >>

BrianHG:
I've placed my caliper's the silver oxide battery in my caliper on my bench supply at 1.8v for 1 day around every 2 years now just as the digits begin to fade.  It's been like this for around 15 years.  Am I doing anything wrong?

Also, I just tied 3.6v to my car starter's lithium CR1216 battery for a day once it died.  After the day, it actually read an even lower voltage, like 1.9v, however I found a trick.  I shorted out the battery for about 5 seconds, and then battery read 3.4v right after.  My car starter has been working fine for over a month, so I cannot say as to how long the recharged lithium will last.

Got to love a bit of over enthusiastic greenwash.

Basically you are getting into 'fleet ownership' when you go into rechargeable batteries. Disposable keeps things running so long the stores are open. The last thing some office needs is some battery nazi telling people to recharge stuff all the time.

So I can come home and I want to cook meat then some batteries need to be charged for a thermometer because I was busy with things and I got to find a charger and plug stuff in and give me a fucking break just put some god damn AA's in the fucking thing and GET ON WITH LIFE.

Cook your meat by guesswork, as the Almighty intended! ;D

Update:

The piezo activated wireless doorbell thing has failed after just a couple of years in a moderately dam environment, I have concluded that a primary cell would be more reliable. Particularly as this thing could probably run for many years on a single small cell.

Primary cells can be replaced, the piezo thing looks totally unmaintainable (I opened it, but I wasn't able to see any problem, I guess the magic piezo pixies went on strike)

Red Squirrel:
I wish everything would just switch to using lithium ion cells.  Basically treat protected 18650 or perhaps a new smaller form factor the same way as AA batteries.    They have the advantage of being rechargeable and also having a very low self discharge rate compared to say, Ni-MH.   Ideally a new form factor that is also designed to be handled by the average joe would maybe be in order.  Something with a built in fuse perhaps so that even if you short it out it's not going to explode.  Maybe a poly fuse?
