When I put battery in calculator it still doesn’t turn on. Do I need to charge it first

We didn’t have to. It was already charged when we received it.

It says the battery is rechargeable with no wire. How do you recharge it?

I put it into the calculator and just charge it normally by connecting the usb cable to the TI calculator.

Does this battery come fully charged??

About half charged. I recommend you charge it fully before using it. This replacement battery worked great for me.

Can this be used the replace model #3.7L1060SP?

No, you will need to purchase the same model of battery as in your Nspire. They use different connectors so they are not interchangable.

Super easy install.

Super easy to install. Accidentally left it on the entire day and only lost around 25% of my battery. Great for saving money by replacing the battery instead of buying a new one.

Did the trick!

My TI-84 plus CE calculator was acting up after not using it for a whole semester. When I charged it, it kept flashing and could not hold a battery. Since my 1 year warranty was already up, I took a chance buying this replacement. As you can see in the photo, no more flashing and my calculator is functioning properly again. I did not need to charge the calculator after installing the replacement battery because it had some power in it as it was delivered.

Brought my failed device back to life

It brought my TI-84 back to life. It was stuck in Validating OS, and no amount of resets worked. The old battery was dead as it had not been charged for a long time.
