Lead batteries operate in a constant process of charge and discharge When a battery is connected to a load that needs electricity, such as a starter in a car, current flows from the battery and the battery then begins to discharge. As a battery begins to discharge, the lead plates become more alike, the acid becomes weaker and the voltage drops.

This increases the weight, and thus reduces the specific energy. But in addition, other passive components add significant amounts of weight, as is always the case in practical batteries. Values of the practical specific energy of lead-acid batteries are currently in the range of 25–40 Wh/kg.
Furthermore, Li-ion batteries have higher specific power (500–2000 W/kg [], 400–1200 W/kg [], 150–3000 W/kg []) than Ni-Cd batteries (150–300 W/kg []) and lead …
Most lithium-ion batteries are 95 percent efficient or more, meaning that 95 percent or more of the energy stored in a lithium-ion battery is actually able to be used. Conversely, lead acid batteries see efficiencies closer to 80 to 85 percent. Higher efficiency batteries charge faster, and similarly to the depth of discharge, improved ...
Restoring a lead-acid battery can boost its performance and lifespan. One method is equalization charging, applying a controlled overcharge to break down sulfation. Alternatively, desulfation devices or additives dissolve sulfate crystals on battery plates. Note, severe damage may render restoration ineffective.

A bigger battery is like a bigger barrel, because it holds more energy (water). You might see a 2-volt battery that is rated to store 1100 amp-hours. That means the battery can put out 55 amps for 20 hours. At 2 volts, that means the battery would be making 110 watts at any given time (2 volts x 55 amps = 110 watts).
Efficiency. Lead–acid batteries typically have coulombic (Ah) efficiencies of around 85% and energy (Wh) efficiencies of around 70% over most of the SoC range, as determined by the details of design and the duty cycle to which they are exposed. The lower the charge and discharge rates, the higher is the efficiency.

11.5: Batteries. Page ID. 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 ...
