Most solar batteries have LED lights, digital displays, or voltmeters that directly report the state of charge. If the indication reading is 100%, then the battery is fully charged.
Getting accurate charge readings and ensuring you don't over- or undercharge your battery is just one element of prolonging your battery's life. The simplest way of knowing whether your solar batteries are fully charged or not is to use your charge controller or inverter to check the battery's voltage.
You need to use a shunt resistor to also measure the solar panel's current while measuring the output voltage. You do not say how you know whether the battery pack is being charged or not. With your solar panel, if it has sufficient power to charge at all, it may take days of bright sunshine to charge the battery pack.
Solar charge controllers are designed to regulate the charging process of solar batteries, preventing overcharging and ensuring optimal battery life. They often incorporate various indicators to provide information about the battery's charge status. Here's how to determine if a solar battery is fully charged using a solar charge controller:
Step 3: Identity the fully charged LED: The controller should have a specific LED that indicates a fully charged battery. This is often the green or blue LED. Step 4: Assess the battery charge level: If the fully charged LED is illuminated, the battery is considered fully charged. If not, the battery needs more charging.
Measuring stationary solar batteries with a DMM voltmeter is best, but portable handheld voltage testers also work well. Built-in analog volt meters eliminate guesswork by reporting the actual battery voltage, which maps to the state of charge levels. However, the relationship between volts and charge percent varies by battery chemistry.
Charging time depends on: Under ideal sun conditions, size compatibly matched panels and batteries refill charge in 4-8 hours for lead acid or 2-3 hours for lithium ion.

Sealed lead acid batteries need to be kept above 70% State of Charge (SoC). If you are storing your batteries at the ideal temperature and humidity levels then a general rule of thumb would be to recharge the batteries every six months. However if you are not sure then you can check the voltage as follows:
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
So many lead acid batteries are 'murdered' because they are left connected (accidentally) to a power 'drain'. No matter the size, lead acid batteries are relatively slow to charge. It may take around 8 - 12 hours to fully charge a battery from fully depleted. It's not possible to just dump a lot of current into them and charge them quickly.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
Lead acid batteries should never stay discharged for a long time, ideally not longer than a day. It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating.
Even in storage, lead-acid batteries naturally lose charge over time, and failure to periodically recharge them can result in irreversible damage. 8.
