Just got a new handheld radio scanner, and am using rechargeable NiMH
batteries in it (four AA).
The manual, and the Forums for the radio, really don't provide a decent
explanation for the re-charging
techniques in the radio. I can of course use an external re-charger, but
would like to use the radio's built in one, for now.
The radio apparently just recharges for a specific number of hours, which is
The default is 16 hours. It says that it charges at a current rate of 150
But everytime you turn the radio on and off and then back on again, the
timer resets to 16 hours.
So, it seems very easy to overcharge the batteries.
Any potential problems if the batteries already have a full, or nearly full
charge, and the radio resets and wants to keep charging them (again) for
another 16 hours ?
Sure seems like a poor way of doing it; I would have thought that they would
monitor the voltage of the battery directly, and not use this kind of
scheme. Probably a bit cheaper, though in circuitry.
Any potential over charging problem ? Caveats ?
Thoughts on ?
