I like the Hakko design; there's basically a collar that goes over the whole tip so you've got tons of threading holding the tip to the iron.

As for battery chargers it depends on the chemistry and whether or not the charger is some horribly unsafe piece of chinese shit.

NiMH is pretty robust compared to Li-Ion so it's not too picky about how you charge it. Constant current, tapering current or pulsed charging all work. Pulsed is probably best since it discourages dendrite formation. The one thing they all have in common is that the charge voltage is 1.4V.

Most "smart" chargers will periodically stop charging and check the battery open circuit voltage to see if it has reached 1.4V, at which point they stop charging.

You could also monitor resistance and look for a sudden spike that would signal the battery's end of charge, but this is a lot more involved and requires a sensitive detector.

It means it'll draw 100mA if you hook it up to a 12V power source.
