Toshiba laptops are a wildcard. They have used "buried" primary batteries (must fully disassemble the notebook), and some are easy (such as my like mom's old L755 (this was cheap junk, I'm glad it kicked the bucket) where it was under the RAM door. Others (Read: low-cost new, often "disposable"; these were unserviceable by design) use the soldered CMOS battery :-(. It makes CMOS battery repairs a complete PITA.
This variation is why the expert response is this:

• Avoid all Toshibas that are new enough to have this garbage (how I do it)
  • The exception is vintage ones in nice condition - think anything up to Pentium II and MAYBE PIII. PIV and up are "modern" or are in the process of cooking their guts due to high CPU temperatures (or are already dead).
• Look up the motherboard and base it on that (not always possible to see both sides, but if it's not visible on the bottom, it's often soldered)
• Negotiation if it is (I don't bother)

This one has a soldered CMOS battery -- not an easy DIY job! If you want to do this, you need a tabbed battery (or a battery and spot welder to transfer the tabs), and make sure it isn't rechargeable. On some of these, the cell is "rechargeable" rather than a "primary" battery like the socketed ones. If the motherboard expects a rechargeable one and it's replaced with a non-rechargeable primary, it will explode. This was a routine issue with Toshiba for years.
