All depends on how good the battery charger is. The best treatment for a lead acid battery is to maintain a trickle charge after recharge. The best treatment for a lithium ion battery is to cut the charge to zero. The charger could be doing either and still be drawing 20mA for its own purposes.

Electrolyte: The electrolyte in a lead-acid battery is a mixture of sulfuric acid and water. It serves as the medium for ions to move between the positive and negative plates during charging and discharging. The concentration of the electrolyte affects battery performance; a fully charged battery has a higher acid concentration.

I have a question: John Fetter sugested a method to see if a battery is fully charged: "If you want to know if a lead-acid battery is fully charged or not, simply put it on a C/50 charge and watch the voltage. The voltage of a fully charged battery will rise to a plateau which will be in the region of 2.55 to 2.65 volts per cell.

When charging lead acid batteries, it is crucial to start the day fully charged and charge the battery every day after 15 minutes or more of use. Failure to allow the batteries to fully charge before the next use will diminish the life of the battery.

The length of time it takes to fully charge a sealed lead-acid battery using a float charger will depend on the capacity of the battery and the output of the charger. Generally, it can take anywhere from several hours to several days to fully charge a battery. Is there any risk of overcharging a sealed lead-acid battery with a float charger
Learn MoreLead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems) With the CCCV method, lead acid batteries are charged in three stages, which are constant-current charge, topping charge and float charge.
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.
Below is a chart I found of the changing resistance of a lead acid battery compared to state of charge, however, the charge acceptance is higher when it is discharged compared to when it is charged. How does this happen with a higher resistance that gradually gets lower? I'm also assuming a constant charging voltage from an alternator.
The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries. With higher charge currents and multi-stage charge methods, the charge time can be reduced to 8–10 hours; however, without full topping charge. Lead acid is sluggish and cannot be charged as quickly as other battery systems. (See BU-202: New Lead Acid Systems)
Lead acid batteries need a specific 3-stage charge process 6 in order to preserve their condition. In practice, if you don't discharge a battery beyond 50%, it takes less time to recharge the battery 7. It can be a good idea to hookup unused batteries permanently to a 'tricklecharger'.
The charging voltage should also be adjusted according to the battery's temperature, as higher temperatures require lower voltages to prevent overcharging. When it comes to charging a new lead acid battery, it is important to use the right charging current to ensure a longer lifespan and optimal performance.
