Hi.

This is primarily for Mark, although other HTX202 users might find it 
useful, as well.

I was on Batteries America's web site this afternoon 
(http://www.batteriesamerica.com).

For the Radio Shack HTX202, they have a large number of battery packes, 
both NiCad and NiMH types, and two battery chargers listed.

They have a wall charger for $12.95 if you don't mind slow charging the 
battery, or if you want fast charge capability they have a drop in smart 
charger for $54.95.

Those who remember the Icom BC35 or the Mr. NiCad BC350 might shudder at 
the mention of the fast charger as these older chargers used a thermal 
couple to sense when the battery was fully charged by sensing when the 
battery was starting to get hot.  The problem with these older chargers is 
that you had to overcharge the battery to a degree to get the battery hot 
enough to shut the charger off, and sometimes the battery would get hot 
enough to melt the plastic in the case causing the charging contacts to 
migrate into the battery case, permanently shutting the battery charge off!

Well, this newer charger actually uses smart charging technology that 
measures the charge on the battery and switches the charge rate down to a 
trickle charge when the battery is fully charged.  It does not use the 
thermal couple and should be much less destructive to the battery.

So, there you go, Mark.  The answer to your problem.
