Lithium Battery Depth of Discharge, State of Charge & Capacity

This is also not the case with lead-acid batteries which have significantly reduced capacity of up to 50% as the rate of discharge increases. Lithium batteries provide 100% of their rated capacity, regardless of the rate of discharge, while lead-acid batteries typically provide less usable energy with higher rates of discharge.

Battery Acid Specific Gravity

However, it has been demonstrated that battery acid when the battery is fully charged has the maximum density at 800F or 26.670C as the temperatures drop below 800F, the battery will contract increasing the specific gravity of the acid. As temperatures raise above 80 0 F, the battery acid expands lowering the specific gravity of the acid.

@Ann Yes, if its a lead acid battery there should be permanent damage if you stored it for two years and never charged it. As you can see, all lead acid battery have a natural discharge rate between 1% to 20% monthly, so at 20% monthly your battery would be 100% discharged in just 5 months and that is using the worst case scenario discharge …
