As a general rule, the higher the voltage, the more charge the battery has. However, the relationship between voltage and state of charge is not always linear. For example, a fully charged 12-volt lead-acid battery will have a voltage of around 12.8 volts, while a partially discharged battery may have a voltage of 12.2 volts or less.
If the battery voltage is not increasing rapidly, the battery is dead. Which means it should go from close to 0V to 0.5/0.8V in just a few minutes (measured when it is not charging). I recommend not doing this if you do not know what current limiting is or if you do not have any means to achieve and verify the actual current limit
