Is a cheap HDMI cable as good as an expensive one?

PSA Pet Peeve: people selling those ripoff HDMI cables. For non-120hz, plain old TV, a cheap one works just as well.

All the TV and device have to be able to tell is:

"Is that a 1 or a 0 coming over the wire?"

Pretty black and white issue. Pretty much literally.

Kind of like this: can you tell the difference between sticking your tongue on a watch battery and not doing it?

That's 3 volts. HDMI is slightly more. Basically.

Now, for longer runs, higher refresh rate, 3D, 4K, etc etc. then it might make a difference.

But you can get a cheap cable so cheap you might as well try it.

TiVo, Xbox, Roku 3, soundbar....all the stuff I have runs just fine on cheap cables.

Now please use my Amazon link to buy one:

Looks like about $4.50 will put one in your hand to try.

Nissan Leaf / Chevy Bolt Key Fob Remote Battery. And: What's the difference between a CR2032 and CR2025?

Please use my links and support my site. 

Link to CR2032's on Amazon:

If you insist, the CR 2025's are here:

The thickness is the difference. The CR2032 is .7mm taller. It fits fine in the Nissan Leaf key fob.

The nice thing is at has 225mAh capacity vs the 165mAh in the CR2025. (Ore more. One seller on Amazon claims 600mAh capacity which means the battery would last FOUR times as long in the Leaf fob.)

So, you'll replace it about less often, if your time means anything to you. Plus the price difference is negligible.

Anecdotally, I see a lot more devices around that use a CR2032 for probably that reason: 36% more capacity so changing it less often is a good thing. And in most devices a .7mm height difference isn't anything worth considering.

If you're really curious what the numbers mean, the '20' in 2025 is the diameter in mm, and the '25' is the height, so as you can see, 32-25=7 so one is .7mm thicker than the other.


I bought a Chevrolet Bolt, and it uses the 2032, so now I can use the same battery in both remotes. :)
