Solar trickle charger q.

I plug in a small solar panel into the cigarette lighter socket and I
measure 19 volts at the battery cables. (disconnected)
but the battery ( new ) seems to be losing . I do listen to the radio.
why is this not charging the battery?
TIA

With the battery disconnected, the voltage could be anything.
What does it measure with battery connected?

With a fully charged battery, you need about 13.5V just to keep it
charged for long term non-use.

I doubt that the solar cell will provide enough amps to re-charge
a discharged battery.

It seems to be connected properly.
How many Watts is the solar pannel?
It is possible that it gives less amps than what you consume with the radio.

A typical 5-6Watt sollar pannel will provide 0.45 to 0.5 Amps to a 12V
battery, on a sunny day, with the pannel perpendicular to the sun's rays.
If not perpendicular it will provide less than that.
A typical radio will consume a bit more than 0.5 Amps (a high power stereo
system will consume much more than that).
