Lead–acid batteries designed for starting automotive engines are not designed for deep discharge. They have a large number of thin plates designed for maximum surface area, and therefore maximum current output, which can easily be damaged by deep discharge. Repeated deep discharges will result in capacity loss and ultimately in premature failure, as the disintegrate. A lead-acid battery usually has a capacity of 100 kWh. Its usable capacity varies with depth of discharge (DoD). At 50% DoD, the usable capacity is about 50 kWh. [pdf]
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.
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. The most important lesson here is this:
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.
Lead acid batteries often can't use all available solar power to charge because they just can't charge any faster, no matter their capacity. This means that even though there would have been enough energy available to fully charge the batteries, it was not available long enough to fully charge the batteries.
This article describes the technical specifications parameters of lead-acid batteries. This article uses the Eastman Tall Tubular Conventional Battery (lead-acid) specifications as an example. Battery Specified Capacity Test @ 27 °C and 10.5V The most important aspect of a battery is its C-rating.

Generally, the negative electrode of a conventional lithium-ion cell is made from . The positive electrode is typically a metal or phosphate. The is a in an . The negative electrode (which is the when the cell is discharging) and the positive electrode (which is the when discharging) are prevented from shorting by a separator. The el. The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh. Lithium battery cells can have anywhere from a few mAh to 100 Ah. [pdf]
Lithium ion battery capacity is the utmost quantity of energy the battery can store and discharge as an electric current under specific conditions. The lithium ion battery capacity is usually expressed or measured in ampere-hours (Ah) or milliampere-hours (mAh).
The capacity of a cell is probably the most critical factor, as it determines how much energy is available in the cell. The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh. Lithium battery cells can have anywhere from a few mAh to 100 Ah.
Here we will look at the most important lithium ion battery specifications. The capacity of a cell is probably the most critical factor, as it determines how much energy is available in the cell. The capacity of lithium battery cells is measured in amp-hours (Ah) or sometimes milliamp-hours (mAh) where 1 Ah = 1,000 mAh.
Even when they are the same size, different types of lithium-ion batteries can have different capacities. A lithium cobalt oxide (LCO) battery, for example, may have a greater capacity than a lithium iron phosphate (LFP) battery of the same size. The capacity of a battery can also be affected by its design, such as its size and number of cells.
1. Battery Capacity (Ah) Battery capacity is a critical indicator of lithium battery performance, representing the amount of energy the battery can deliver under specific conditions (such as discharge rate, temperature, and cutoff voltage), usually measured in ampere-hours (Ah). For example, a 48V, 100Ah lithium battery has a capacity of:
Occasionally lithium battery cells are marketed with just a C rating and not a maximum current rating. This can make it easier to compare the power level of battery cells of different capacities. As long as you know the capacity of the cell, you can use the C rate to quickly calculate the maximum current rating of the cell.
