Ok, we all agree on NiCad batteries.
Several departments have inquired on a "slug" for their conditioner/analyzer for use with the HT750/1250 radios. These radios use NiMH. Most manufacturers are against using a conditioner on these batteries.
What is good is that they develop no memory and can charge whenever you want. The down side is that, even though they have a higher current output, as their charge rate decreases it isn't a gradual downward linear fall like you have on a NiCad. WHen the NiMH starts to drop, it slowly decreases it's available voltage, then all of the sudden it rapidly drops off. Some price to pay for more power.
What's everyone's input on the conditioning?
NiMH batteries, now

Hi:
With respects to " Conditioning " you may
have as many view points as was directed
with Ni-Cads.
However, my view point is that Conditioning
a Battery Prior to giving a repaired radio
back to the customer is good service
and will certainly make them happy.
Also, conditioning a battery allows one to
" Know " for sure the battery meets specs
at the time it was charged / conditioned.
I have seen <b>Brand New batteries FAIL</b> right out of the BOX due to Primary Cells being defective. That is to say the Battery may work for a Month or two, and then will start giving poor performance. Even happens
with about 15% of the Motorola ones
Most persons who do not have a good analizer,
just use the battery and live with the poor
performance until it dies completely ( hopefully within the warrantee period )
A " good " battery conditioner allows one to
see a digital readout of the current over a
specified period of time. Seeing several
batteries with close results is a indication
of a good battery line, and that the target
battery is probably OK.
NOT all mfg's make good batteries !! Some are
Good, Some are horrible...I will not mention
the ones that are bad since it may offend a select group of persons....but they probably
already know.
Ya, I know, I know, but I do stick with the
Horrible Prices of my Parent company ~//~
only from the stand point of the 18 Month
Warrantee....I guess they finally got the
messages I have been sending for years about
the competition....
Also, Exercising a battery once a month is
a good idea too....These newer batteries tend
to die right after they are made....and they
do have a performance vs shelf life issue.
Its always best ( In my opinion as well as the Factory OEM's of batteries to keep them
in a cool / dry place ) Some have indicated
they have had good results by placing batteries in a Refrigerator or Freezer, which
is truly against my view points as I have tried that too with little to poor results.
This applies to Ion, Ni-cads, Metal Nickle Hydride, ect....I have found batteries really
just do not work well when they are kept cold
and then returned to normal room tempetures.
Most of the time I just ended up with moisture inside the battery case, and corroded contacts....I was not really able to extend the life of the battery....Others
have indicated good results.
