Re: Do NiMH packs come with fuses? Nope!!


 

Mike,

The OPP was my first choice but after 2 weeks, Gigaparts still doesn't
have
any stock of them. Heck, we're all in the same town too!
I ordered mine direct from W4RT Electronics and had it in a few days. Have
you checked with GigaParts recently? I talked to George at GigaParts
Tuesday on another matter and understood that they were either in stock or
expected shortly.

Would be curious to know what kind of failure you had. I'd bought the Maha
drop-in charger (C888?) for my HTs before and used it to charge one of the
RS packs last night. There was a little bit of smell that made me believe
that it was getting hot inside.
My Maha C777plus goes to 22.3 volts within seconds after the termination of
the 3 minute surface charge application with several different NiMh packs.
I didn't wait around for the smoke :-) It is now on the way back to Maha
for warranty repair.

The worst part of charging in the radio is that is time-based and doesn't
give an indication of when the batteries are fully charged. I'm wondering
if some of the temperature sensitive labels could be applied to the
battery
door to pick up the sharp temperature increase that occurs when the
battery
is fully charged. A temp sensor and a piezo beeper might work as well.
Mike, I'm just too impatient and short of time to watch labels on the door.
Even a piezo beeper triggered by a temp sensor means that I have to be on
the scene to hear it. I guess this is an individual value judgment and
others may or may not share my views.
