The radio displays a message indicating "Battery Low Start Engine."

Can someone provide assistance?
I own a Sportage mk 3 and the radio is displaying the message "Battery Low start engine." The time does not appear on the radio display when the radio is switched off.

During periods of low battery status, especially in winter, a reminder prompts you to start the engine and charge the battery. You may have a defective battery. They may register reduced voltage levels during extended periods of stop-and-go operation or brief trips. Uncertain about the time presentation. I will inspect it the next time I am driving.

Two further items are, The automobile had been stationary for 2 months before displaying the notice on the radio and other mentioned defects.
When the radio was turned off while the engine was running, it displayed the time in large figures. Additionally, if the radio was on, it turned off when the engine was switched off.
The automobile is a 2013 MK3 model and lacks a stop/start feature.
The battery is fully charged and is fresh. Half a year ago

The start/stop button is located on the right side of the dashboard below the steering wheel and is marked with the letter A. The 2-month period of inactivity may have resulted in a depleted battery, maybe due to a faulty cell. Having 5 functioning cells at 2.3 volts each would yield a total of 11.5 volts, without accounting for the voltage in the defective cell. Perform a load test to eliminate it as a potential cause. Defective grounds may lead to inaccurate measurements, as well as poorly connected or corroded battery connections.

To address the missing clock, you must reset the radio equipment. Locate the little hole at the top of the device and use a pen or similar object to push into the hole to reset the unit. Your clock should return.

This is a photo of my Radio Unit without a little button for pressing on the radio.
This radio lacks Sat/Nav. Any other recommendations would be appreciated.

If there is no little reset hole, the reset option is likely located in the menu settings. Alternatively, another member who has the same radio may provide advice.

It seems to me that your problems are likely due to a defective battery cell or faulty terminations. You should get the battery thoroughly checked, rather than simply using a voltmeter for a quick check. The display may indicate 12 volts, but this reading lacks significance without a suitable load. Consult a qualified vehicle electrician to examine it, since else it would be purely speculative.

The battery, which is around 6 months old, underwent testing at a dealership using a tester. The results indicated no issues with the battery cells and showed it to be 98% functional.
Any other thoughts, please.

Attempt to detach the battery for 10 minutes to see whether it resolves the issue.

You must locate a proficient car electrician.

I acknowledge that my message was not entirely correct, but I aimed to make my response concise and focused. I will remember this for future answers. The assistance provided did not lead to a solution for the original poster. Any suggestions made here are speculative, and it is recommended that the individual seeks out a skilled auto electrician to accurately identify the issue.

When you had the battery examined at the dealership, could they not resolve the radio problem?

[CelestialSeeker]

They proposed a fee of £120.00 for a diagnostic but could not guarantee identifying the error.
