The time it takes to discharge a sealed lead-acid battery can vary depending on the load and the battery’s capacity. It is important to monitor the battery’s voltage during the discharge process to ensure that it does not drop below the recommended threshold.
The charging process of a lead-acid battery involves applying a DC voltage to the battery terminals, which causes the battery to charge. The discharging process involves using the battery to power a device, which causes the battery to discharge.
Charge a lead acid battery before storing. Lead acid batteries can be stored for up to 2 years. It is generally advisable to periodically monitor the battery voltage and charge it when it falls below 70 percent state-of-charge (SoC); however, lead batteries typically have brand specific readings.
Proper maintenance of sealed lead-acid batteries involves regular charging and discharging cycles, keeping the battery clean and dry, and avoiding exposure to extreme temperatures. It is also important to check the battery’s voltage regularly and to replace it when necessary. What is the charging and discharging process of lead acid battery?
Sulphuric acid is consumed and water is formed which reduces the specific gravity of electrolyte from 1.28 to 1.18. The terminal voltage of each battery cell falls to 1.8V. Chemical energy is converted into electrical energy which is delivered to load. The lead-acid battery can be recharged when it is fully discharged.
The following are the indications which show whether the given lead-acid battery is fully charged or not. Voltage : During charging, the terminal voltage of a lead-acid cell When the terminal voltage of lead-acid battery rises to 2.5 V per cell, the battery is considered to be fully charged.

What is a safe max. discharge rate for a 12V lead acid battery?
$begingroup$ I have a 12 volt 9 amp hour battery pack and I use it mostly for charging my phones and a light and a radio but I have used it to run my 2.7 amp water pump from time to time. I noticed it doesn''t go down but maybe halfway. After a 15 min shower the battery bank go down maybe from 13.6v to 12.8v I have been living on batteries for the past 5 years.

Battery discharge time depending upon load
In many types of batteries, the battery cannot be fully discharged without causing serious, and often irreparable, damage to the battery. Manufacturers usually specify the depth of discharge (DOD) of a battery, which determines the fraction of power that can be withdrawn from it. For example, most car batteries have a DOD of 20%, so only 20% of capacity can be withdrawn.
