HP 32SII success and woes

I suggest you use all 3 cells in series but install a series silicon diode to drop the voltage by about .6 volts. That will net you about 3.9 volts and keep the low battery indicator from turning on and the cells tight in the battery compartment. The low battery indication is set to about 3.5 volts in the 32sii.

Thank you for this suggestion. I'll have to explore where to place the series diode and do some practice soldering before embarking on replacing the capacitor as well.
