Figure: Relationship between battery capacity, temperature and lifetime for a deep-cycle battery. Constant
The battery''s AH rating goes down the faster you use it. This is not the same thing as saying you use up what is available faster, but you actually decrease the total overall capacity itself. To ensure that ratings are given in a realistic way, lead-acid batteries have a few parameters on how they get that “AH” rating.
A lead acid battery can supply a maximum of around 1400 amps, depending on its size and specifications. Cold Cranking Amps (CCA) measure the battery''s

Lithium-ion batteries are lightweight compared to lead-acid batteries with similar energy storage capacity. For instance, a lead acid battery could weigh 20 or 30 kg per kWh, while a lithium-ion battery could weigh 5 or 10 kg per kWh.
Sulfation is a key factor in decreased battery capacity, particularly in lead-acid batteries. It occurs when lead sulfate crystals form on the battery plates, blocking the battery''s ability to hold a charge. This reduces the active surface area of the electrodes, limiting the amount of energy the battery can store.

Age of the Battery: Age naturally impacts battery capacity and performance. Lead-acid batteries typically have a lifespan of 3 to 5 years. A significant decline in performance often occurs as a battery approaches the end of its rated life, as noted by the National Renewable Energy Laboratory.
It turns out that the usable capacity of a lead acid battery depends on the applied load. Therefore, the stated capacity is actually the capacity at a certain load that would deplete the battery in 20 hours. This is concept of the C-rate. 1C is the theoretical one hour discharge rate based on the capacity.
Personally, I always make sure that anything connected to a lead acid battery is properly fused. The common rule of thumb is that a lead acid battery should not be discharged below 50% of capacity, or ideally not beyond 70% of capacity. This is because lead acid batteries age / wear out faster if you deep discharge them.
It's best to immediately charge a lead acid battery after a (partial) discharge to keep them from quickly deteriorating. A battery that is in a discharged state for a long time (many months) will probably never recover or ever be usable again even if it was new and/or hasn't been used much.
A battery at 10.5 - 10.8 volts at rest is probably damaged. A lead acid battery should never be below 11.80 volt at rest. ↩ 'bad' battery protection solutions will just start to oscillate as the battery voltage recovers (above the cut-off threshold) when the load is removed.
A typical lead–acid battery contains a mixture with varying concentrations of water and acid. Sulfuric acid has a higher density than water, which causes the acid formed at the plates during charging to flow downward and collect at the bottom of the battery.
The capacity of a lead–acid battery is not a fixed quantity but varies according to how quickly it is discharged. The empirical relationship between discharge rate and capacity is known as Peukert's law.
