I have a Sony D-150 (US equivalent is D-15) that I adjusted carefully according to the service manual. But it is still very sensitive to shock: it skips when I knock it lightly. Someone recommended me to replace the spindle motor, what I did, but no improvement. The eye signal and the laser current is within tolerance. Is the shock sensitivity normal at this early model? My other question is the lead-acid battery BP2-EX (4V, 600mAh), is there any alternative for replacement?

Vintage cd players like D15 can tolerate a certain shock from outside. But only a little shock it can prevent. I think maybe you hope too much for it if your adjustment is correct. Motor should be replaced only when music track skips. In most situation replacing motor is unnecessary.
There is a solution about your dead battery. It can be replaced by a Li-On battery, uses same battery cartridge with the original battery. Common capacity is 4.2V 1000MA. Considering to its special demension, maybe it's hard for you to find one. If more than 10 batteries are needed, I'll consider to prepare a batch for you guys. Accordingly, charger circuit should be modified and maybe your transformer will be asked to check whether it will qualify for chargering a Li-on battery.

Sorry if I'm stating the obvious here, but Sony players are common enough at thrift stores and yard sales that the cheapest solution may be to swap the spindle/pickup assembly from another player. If the assemblies are the same shape, they probably interchange, so you can keep a rarer model (wired remote, digital out, backlit car model, whatever) going by sacrificing a more basic model.

Good suggestion! If they still contain some valuable components without aging.
