This does not mean I am remaining exclusively with Dell has been my practice. Extra batteries from Dell are three times the perfectly good third-party replacements found on Amazon. I will be doing a little more investigation into other companies like Lenovo and HP. If they allow for generic replacement batteries to be used without a BIOS block, then they are definitely a better investment.
I did spend some time yesterday evening disassembling an official Dell battery (which was dead). I thought maybe I could either swap out the actual lithium-ion packs or extract whatever circuitry which identified the units as officially Dell. The batteries are not a something that can be simply disassembled. Neither of those theories were feasible.
