At the Dollar store I see Super Heavy Duty Batteries for Low Drain Devices. WTF does that mean?
Battery design and chemistry can be optimized for different things ... low internal resistance for high-current draw devices, low self-discharge for long-life / low-current draw devices, resilience against cold or heat, etc..
OTOH, about the only thing I've ever gotten at a dollar store is one less dollar, and something I'm now charged with disposing of. YMMV.
In my experience "Heavy Duty", when applied to consumer batteries, means you are about to be ripped off.
"All Natural" is a similar means nothing phrase that is often applied to food in an attempt to fool the customer into believing they are not, in fact, buying something that came out of the ass-end of a petrochemical plant.
My understanding is that "Heavy Duty" usually means Zinc-Carbon or Zinc-Chloride chemistry. I avoid these like the plague. Alkaline cells can be had quite reasonably in multi-dozen quantites, last at least twice as long, and are less prone to leakage. I don't see a reason to keep more than one type around. Even in low-drain applications, alkaline cells are my preference. Seems I usually end up throwing out the TV before I have to change the battery in the remote control.
Seems like there's something wrong right there. How long does a TV set last these days before it gets thrown out?

Depends. I have a 32" TV that is collecting dust. It'd be a bit of work to throw it. It's a flat panel but who said it's not heavy?!

2 - 4 years, unfortunately.

Until the tin whiskers kill it.
When the HDMI folks decide it's time to bump the version number for yet another "gee you gotta have this" feature that wasn't planned into the spec from day one.
Interesting that composite cables are still on version 1.0.
PCs are nearly as bad now. We have VGA, DVI, HDMI, and DisplayPort. Sometimes you even get lucky enough to have a computer with the same interface type as the screen you'd like to use.
I do like the DisplayPort better than HDMI from a mechanical standpoint. I don't know why more HDMI cables don't fall right out of their sockets. Especially when most of the cables are just a bit larger in diameter than a firehose 
I like that it's a flexible interface that can potentially drive multiple displays in a daisy-chain.
What I DON'T like is that, at this point, the last thing we need is yet another connector, particularly one that will need an adapter to convert to something you can actually use on any given monitor. (I don't know about you guys, but I have yet to lay hands on a screen that actually has a DP input.) As a bonus, passive DP-to-HDMI (or -DVI) conversion cables won't work unless it's a DP+ port, which is a fun surprise.
Not to mention the "mini" variants that Apple will use on their laptops and everyone else will use on their tablets, etc.
Seriously. The industry has lost its freakin mind.
I don't know about you guys, but I have yet to lay hands on a screen that actually has a DP input.
I'm sitting in front of a pair of 24" 1920x1200 Dells that have DVI, VGA and DP, but no HDMI.
And yup, all three on each display are wired!
AWOL:

Haaa, that sounds like a rig that won't be replaced by a smartphone or tablet anytime soon.
Old pair of 20" Dells here, 1600x1200. Almost impossible to find 4:3 aspect ratio these days. Also hard to find the adjustments that these have, pivot, tilt and height.

Oh, I've got those as well!
Plus laptop.

Sure but in addition to, not instead of!

OK, now I'm curious. Whatcha got going on there? 
Just ordered a Viewsonic 24" that has DP, so I guess I'm about to make a liar of myself. I've gotten used to a pair of very nice Sony LCDs I bought back when they were all expensive so people cared more about picture quality than price point. But, if the new one looks at least as good, I'm planning to go for a trio of them. From various work setups, I find two isn't enough, but four is too many. Three is Goldilocks territory. XD
I remember an interview with the author Terry Pratchett.
When asked why he had six monitors, he answered "Because I don't have room for eight".
Whatcha got going on there?
Two desktop workstations and a laptop docking station.
