Toshiba laptops are a wildcard. They have used "buried" primary batteries (must fully disassemble the notebook), some are easy like my mom's Toshiba L755 (cheap junk, I don't miss it) where it was under the RAM door. Others (Read: low-cost new, often "disposable"; these were absolutely designed to be evil to maintain on purpose) use a soldered CMOS battery. These soldered batteries are a absolute PITA to replace for non-techies (then again, we RUN from these). 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 truly vintage ones in nice condition - think anything up to Pentium II and MAYBE PIII. PIV and up are "modern".
- 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 spot welder), and you need to make sure it isn't rechargeable. On some of these, the cell is "rechargeable" rather than being 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. It's nonsense like this why Toshiba is not missed since they left the market.

@nick ,
Wouldn't recommend a welder.
The battery model number should be printed on the battery, so it should be easy to find using that information.
Cheers
@jayeff Yeah her Toshiba with the DMCA abuse years ago ruined Toshiba for me. I despised that thing, and was quick to dump it when she was willing to part with it. In hindsight, yeah I thought mentioning Toshiba's nonsense would clarify throwing her old laptop out was a welcome day would suffice :/.
She still prefers "consumer grade" for the warranty, but she's seen what a proper business class laptop is built like... Aluminum chassis all-around (not mixed), magnesium or a mix. In some cases, CFRP and magnesium like some of the really nice Dells before they started soldering the 7000 series components down to the wireless card. If they bring the magnesium/CFRP chassis to the 5000 series as a premium option, I'd be happy with that compromise.
Sadly, we're still stuck with these "unserviceable CMOS battery" laptops because people bought them without checking, and Toshiba loved the soldered tabbed cells on a lot of the cheap laptops, for years. Unless the new owner is willing to pick up a soldering iron, these will enter the waste stream as the coin cells die. Ugh, I hate that Toshiba ever decided to freaking solder a WEAR ITEM to the motherboard. Sockets are what? $1-2 in small amounts, so it would be fractions of a cent to make the battery serviceable. You could modify these with a CR2032 socket and 2 wires (tack down the socket in an area where the board and palmrest won't disagree), but it doesn't change the fact that you need to fix the unserviceable design (and in many cases, the laptops aren't worth the trouble).
