After owning a new 125 for about two weeks I decided to see what kind of charging rates and/or drain the unit has while plugged in to a power source. This was a very basic test but it ended up pointing out to me a potential problem with either the scanner's charging circuit or the batteries. Here it goes.
The start of the test was using a cigarette lighter adapter for the USB chord and the screen light was "off". Was in the SCAN mode and receiving signals. Power level in upper right corner indicated 3.95. After about 20 minutes of scanning the power level was 3.90. The unit was actually discharging while in use.
Changed to the HOLD mode (monitor only one channel). After about 15 minutes the power level went from 3.90 to 3.87 with the USB chord still plugged in. Still discharging while in use.
Went home and plugged USB chord into a USB wall adapter and charged the scanner over night. Approximately 10hrs. Screen said CHARGE COMPLETE . Turned unit on and the power level was 3.90. (Less than what I started with the day before.) Then I turned scanner off. About three hours later turned scanner on. Power level stated 3.85. Unit seems to be draining the batteries even when off.
Plugged unit back into the cigarette lighter adapter but after about 15 minutes noticed the back of the battery compartment warm to the touch. Unplugged everything. Took batteries out. Double checked the battery setting. It is set to NiMH. Put batteries back in and plugged USB charger back in. After about five minutes screen said BATTERY ERROR.
Unplugged charger and checked power level. Screen said 3.90. Turned scanner off. About 30 minutes later checked power level again. Now it was 3.67. Batteries discharging at a faster rate now when scanner is off.
Thought I had one bad battery. Checked battery level on meter. One was 1.25v the other was 1.27v.
I am at a loss and am asking for advice. Back to Uniden for repair or try new batteries? I am using the batteries that came in the box.
