When the battery is fully charged, the acid is concentrated, and it has a specific gravity of around 1.265. As the battery discharges, the acid becomes less concentrated, and its specific gravity drops. When the battery is fully discharged, the acid has a specific gravity of around 1.120. Battery Casing. The battery casing is the outer shell of the lead-acid battery. It …
Do not deep discharge the battery less than 1.7V per cell. To store a lead acid battery, it needs to be completely charged then the electrolyte needs to be drained. Then the battery will become dry and can be stored for a long time period.
Therefore, it is essential to check the voltage and/or specific gravity of the battery and apply a charge when the battery falls to 70 percent state-of-charge, which reflects 2.07V/cell open circuit or 12.42V for a 12V pack. What is the best way to maintain a lead-acid battery during storage?
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:
All lead acid batteries discharge when in storage – a process known as ‘calendar fade’ – so the right environment and active maintenance are essential to ensure the batteries maintain their ability to achieve fill capacity. This is true of both flooded lead acid and sealed lead acid batteries. The ideal storage temperature is 50°F (10°C).
The batteries should be charged in a well-ventilated place so that gases and acid fumes are blown away. The lead-acid battery should never be left idle for a long time in discharged condition because the lead sulfate coating on both the positive and negative plates will form into hard crystals that will be difficult to break up on recharging.
On the other hand, storing batteries in a cold environment can cause them to freeze, which can also damage the battery plates and lead to reduced capacity. Therefore, it is essential to store your lead-acid batteries in a dry and temperature-controlled environment to prevent damage.

Figure 4: Comparison of lead acid and Li-ion as starter battery. Lead acid maintains a strong lead in starter battery. Credit goes to good cold temperature performance, low cost, good safety record and ease of recycling. [1] Lead is toxic and environmentalists would like to replace the lead acid battery with an alternative chemistry. Europe ...
Lead acid batteries must always be stored in a charged state. A topping charge should be applied every 6 months to prevent the voltage from dropping below 2.05V/cell and causing the battery to sulfate. With AGM, these requirements can be relaxed. Measuring the open circuit voltage (OCV) while in storage provides a reliable indication as to the state-of-charge of …
5 Lead Acid Batteries. 5.1 Introduction. Lead acid batteries are the most commonly used type of battery in photovoltaic systems. Although lead acid batteries have a low energy density, only moderate efficiency and high maintenance requirements, they also have a long lifetime and low costs compared to other battery types.
7. Storage Considerations for Lead-Acid Batteries. Proper storage is essential for maintaining the health of lead-acid batteries, particularly when they are not in use for extended periods. Store Fully Charged: Always store lead-acid batteries fully charged. If a battery is stored in a partially discharged state, sulfation can occur, which will ...
In cold ambient batteries need to be fully charged as fully charge batteries safer than the empty batteries in respect of freezing. Do not deep discharge the battery less …
To charge a sealed lead acid battery, a DC voltage between 2.30 volts per cell (float) and 2.45 volts per cell (fast) is applied to the terminals of the battery. Depending on the state of charge (SoC), the cell may temporarily be lower after discharge than the applied voltage. After some time, however, it should level off. During charge, the lead sulfate of the positive plate becomes lead ...
Lead 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 [1] constant-current charge, [2] …

This article examines lead-acid battery basics, including equivalent circuits, storage capacity and efficiency, and system sizing. Stand-alone systems that utilize intermittent resources such as wind and solar require a means to store the energy produced so the stored energy can then be delivered when needed and the resources are unavailable.
A fully charged lead acid battery can be stored for 6 to 12 months under optimal conditions. During this time, the battery will gradually lose charge due to self-discharge rates. …
Charge your battery in a well-ventilated location. Select a location like a garage or large shed. Open a door or window if you can. Good ventilation is important because, during the charging process, a mixture of gases builds up in your battery, and if the battery is overcharged or shorts out, these gases may vent out of the battery.

Primary alkaline and lithium batteries can be stored for up to 10 years with only moderate capacity loss. There is virtually no self-discharge below about 4.0V at 20 C (68 F); storing at 3.7V yields amazing longevity for most Li-ion systems. Finding the exact 40–50 percent SoC level to store Li-ion is not that important.
Sealed lead-acid performance and longevity are unpredictable. Use flooded batteries with pure lead grids. Float at 2.23 V per cell. You can, theoretically, store a FULLY charged sealed lead-acid in a deepfreeze at minus 20-30 degrees C …
