Lawrence, how did you measure that 16.5 volts? Is that the charger's open
circuit voltage, or is that the peak voltage you measure at the battery
terminals when it's on charge?

Should have grabbed one of those $25 Iotas from Electronic Goldmine while
they were around, those regulate voltage.

A simple resistor won't limit the output voltage when the current tapers
off. (When the load resistance becomes larger.) It will still go to 16+
volts and ruin your battery.
A simple solution might be to place two, perhaps three, large diodes
(rectifiers) in series with the output.
You can

Lawrence, can you trace
