Scott, I wonder if you have ever dismantled a ordinary Laptop battery and replaced the cells?

A while ago I split one open and found it had industry standard 18650 battery cells installed!

Is it feasible to replace just the cells with a soldering iron? I noticed at the time that the 18650 cells included in that laptop had quite a low AH rating, so wondered about using higher rated ones for more battery life.

Yes indeed, several of them.

No. After researching the subject online, and after seeing the cost of equivelant quality replacement cells plus the work required to solder them in, considered against the cost of discounted OEM replacements, I decided it wasn't worth it.

For my ThinkPads I use only Lenovo OEM batteries, I don't trust many of the lower cost (and quality) replacements due to potential fire and explosion hazards as well as hit-or-miss performance. I've been buying genuine Lenovo batteries at discounted prices from ServerSupply.com for several years now and have never been dissapointed.
