How long does a solar panel take to charge a battery?

I tell you, for example, a large panel with a small flooded lead or gel battery, the charging time will be short, no more than a couple of hours when the solar radiation is good. And in another case a small solar panel with a large gel or flooded lead battery will take a long time to charge.

How to know if a solar battery is no longer useful?

If a 12V battery offers a voltage of 10V or less, it means that it is bad or has communicating vessels that alter its correct operation. In a 24V battery system: 25.4V would be approximately the charged battery, while 23.2V would be the discharged battery.

How to know if a gel battery is bad?

Gel batteries, however, are generally more expensive than traditional batteries and cannot be recharged. This also means that gel batteries cannot be tested with a hydrometer. The easiest and fastest way to test your gel battery is with a digital voltmeter.
