I know that mine survived the 'disposal' procedure for dead batteries because I opened it to see why the motor was whizzing around but the brush wasn't oscillating. The reason was that the shaft connecting to brush to the 'gearbox' was broken and rusty. The battery was fine, indeed, it replaced the failing one in my beard trimmer.
My OralB electric toothbrush has been operating flawlessly for about 10 years. I've no direct knowledge of the battery type inside, but I assume that it is a NiCad. Every 6 months or so I fully discharge the battery and recharge a couple of times. To discharge it, I just turn it on, set on the countertop and let it run until it slows significantly.
Nothing lasts forever, but with proper care, it can provide good value. I've no gripes about my OralB electric. And when it dies for good, I'll likely get another OralB.
I had a delux rechargable model. It broke. For $15 you can buy the AA version and it works just as good or better. The old brushes will not work in the new one.
