That describes the experience quite accurately ;-) > On the charging settings for the battery, it seems to use a constant > voltage mode for at least the latter part of the charging, Yes, there are three phases: - qualification, where it tries to find out if the battery is any good - constant current - constant voltage There's a nice diagram in the PCF50606 manual, figure 41, on page 62. If you skip the qualification, you can just use a lab supply as charger. Very convenient ;-) - Werner
