I just got my HX350S battery back from primecell. I really like the
handheld, even if it's a bit heavy.

They replaced the NiCd with a NiHh and claim that the battery life
will
be double or more. Anyone seen this or have experience with
rebuilds?
It
sure was a lot cheaper than replacing the whole handheld.

On Ham Radios, NiHh has been outperforming the old NiCd for some
years
because it has far less tendency to gain a "memory". A NiCd that
originally has 1000Ah capacity (for example) will quickly drop to
half
that if only half discharged before being recharged.



Hey Vito... you're right, and I've noticed that with other devices.
This
particular VHF battery (the original) was fairly incredible (perhaps
it
was
the radio itself). It never seemed to die. Then, suddenly it wouldn't
hold
a
charge.

Nicads can grow metal crystals which short across the electrodes. It
is possible to fuse these with a short, heavy burst of charging
current and get your battery back.



You mean internal to the battery pack right...

Inside a cell between anode and cathode.

the electrode seats inside
the VHF are fine as far as I can tell.



Ah... thanks for the clarification. All know/care when I need it is it's
charged and it works.

Interesting... I would have to open the battery case though?

I have the charger that originally came with the VHF, but I don't recall if
it's a fast or slow charger.
