TI-36X Pro—Replace the batteries or just get a new one?
Spinning-off from the Casio-991EX thread, rather than veer the Casio thread off track, it seems to me that the TI-36X Pro needs to be completely disassembled *just to replace the battery.* It would just seem easier to buy a new 36X Pro when the batteries expire. Or, am I missing steps that would make it easier to replace the batteries on a TI-36X Pro?

I think you've broken the secret code! This is exactly what TI wants you to conclude, and no doubt influenced the design decisions.

Thanks. Between Spock (not the baby doctor) and Inspector Clouseau, my deductive reasoning skills are sharp.

Definitely just replace the battery. This calculator is too nice to throw away. There are a lot of screws to remove but its fairly to replace the single CR2032 lithium battery. Here is a nice write-up on how to do it by ifixit.

Does TI really make the battery compartment so complicated to access to let users throw the calculator away?

I see this with smartphones too, that have an integrated battery not that easy to replace (well and also the newer nspire). I have one of those smartphone with replaceable battery and it can work even without battery, and that's great.

While I can partially understand the smartphones, as a battery is degraded after 3+ years and the smartphone is hardly supported (all the apps moving to new versions of the OS), I don't understand it for calculators. Those things are mostly eternally useful as most of the operations done in a day are the four basic functions.

Consumerism is really cancerous for the planet.

Wikis are great, Contribute :)

Well, perhaps when I go to Office Depot or Staples, I should let the sales rep do the battery replacement since dexterity and coordination would be in their favour.

In the old days, the sales rep would do that. I am not so sure now.
I still remember they actually test the lightbulbs before selling it (so, NO RETURNS)

From what I saw on YouTube, labor of changing battery outweight the battery itself.
Adding the fact that they may break the old calculator ...

Reminds me of when I took my aging iPhone 6 to Apple for the special $30 battery replacement earlier this year. They accidentally dropped it, and so I just got an entirely new iPhone 6 out of the deal. Waiting on iTunes to restore my backup was a reasonable price to pay!
