Capacity. A battery''s capacity measures how much energy can be stored (and eventually discharged) by the battery. While capacity numbers vary between battery models and manufacturers, lithium-ion battery technology has been well-proven to have a significantly higher energy density than lead acid batteries.
Because galvanic cells can be self-contained and portable, they can be used as batteries and fuel cells. A battery (storage cell) is a galvanic cell (or a series of galvanic cells) that contains all the reactants needed to produce electricity. In contrast, a fuel cell is a galvanic cell that requires a constant external supply of one or more reactants to generate electricity.

During periods of low sunlight …
Besides, inside the battery there is basically an acid (the density might be lower compared to a bleacher but, still an acid). A lead acid battery can be stored for at least 2 years with no electrical operation. But if you worry, you should: Fully charge the battery; Remove it from the device; And store at room temperature
In a lead acid battery, there are flat lead plates that are submerged in an electrolyte solution. This electrolyte contains sulphuric acid and water. When the battery is being recharged, electricity flows through this electrolyte, but water loss occurs as a result. If the car battery is low on water, damage can occur.

The battery terminals in each cell should be fully immersed in the liquid. If the electrolyte solution is below the fill line, it''s time to add distilled water.
Furthermore, the NFPA reports that (based on limited information) flooded lead-acid batteries are less prone to thermal runaways than valve-regulated lead-acid batteries (VRLA). That''s because the liquid solution in flooded batteries can inhibit fire better than the materials inside VRLA batteries can.
