Hello all.

I have a question about charging voltage on a X5105. Mine when on the charger reads 13.9vdc input. But after 12-24 hours charging the battery voltage reads 11.9vdc and never gets any higher. It has always been this way since new. The radio works fine and battery life appears to be fine and the battery holds its charge for long periods of time. So my question for the group is does this seem normal or is there a problem in the making? Is the fully charged battery suposed to be 12vdc or hugher? The radio is about 4 years old with 3.0 firmware installed. Anyone else expierence this issue?
Thanks in advance,
Rick

I may be wrong but seems like someone determined that the battery voltage readout in the radio is in error.?

Hi Rick,

For the times I’ve used in on internal battery only, it goes to about 13.0VDC on a full charge and I recharge it at about 11.5VDC. Fairly wide range with no variation in performance.

The radio works fine until the battery gets down to around 9vdc and then it shuts down.

That sounds like it's better than one might expect.? 9 V. is a lot lower than 12.? I've been an electronics technician and repair man for about 50 years, and shutting down at 9 V. sounds completely normal to me.

A car battery at 9 volts is seriously low, wouldn't be able to start a car, and probably not even light the lights.
