A lead-acid battery’s internal resistance becomes higher the deeper it is discharged. So, the charging algorithm is designed to slowly charge the battery at lower voltage levels. Conversely, the constant current algorithm of lithium batteries is preferable due to the high efficiency and low internal resistance.
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.
Another aspect that distinguishes Lead-acid batteries is their maintenance needs. While some modern variants are labelled 'maintenance-free', traditional lead acid batteries often require periodic checks to ensure the electrolyte levels remain optimal and the terminals remain clean and corrosion-free.
The overall pros and cons for both battery types are:. Higher energy density allows for lighter, more compact designs. Longer lifespan, often outlasting lead acid counterparts. Reduced maintenance needs, translating to potential time and cost savings. Greater energy efficiency with faster and consistent discharge rates.
The core principle of a Lead-acid battery is based on a series of chemical reactions. When the battery discharges, the lead dioxide (positive plate) and the pure lead (negative plate) react with the sulfuric acid electrolyte to produce lead sulfate and water.
Myth: The worst thing you can do is overcharge a lead acid battery. Fact: The worst thing you can do is under-charge a lead acid battery. Regularly under-charging a battery will result in sulfation with permanent loss of capacity and plate corrosion rates upwards of 25x normal.
ELI5: why are there different sized batteries (aaa-D, etc) if ...
The size of the battery changes the capacity (how much total power is stored) rather than voltage. A large D-cell battery will run longer than a AA-cell for the same power draw. The voltage is dictated by the chemistry inside of the battery. Basically, different elements or molecules have different electro-chemical potentials. That''s why ...
