Lithium Vs. Lead Acid: Battery Capacity & Efficiency
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. That means you are able to ...

Six test cells, two lead–acid batteries (LABs), and four lithium iron phosphate (LFP) batteries have been tested regarding their capacity at various temperatures (25 °C, 0 °C, and −18 °C) and regarding their cold crank capability at low temperatures (0 °C, −10 °C, −18 °C, and −30 °C). During the capacity test, the LFP …
Heat Effects during the Operation of Lead-Acid Batteries
Thermal events in lead-acid batteries during their operation play an important role; they affect not only the reaction rate of ongoing electrochemical reactions, but also the rate of discharge and self-discharge, length of service life and, in critical cases, can even cause a fatal failure of the battery, known as "thermal runaway." This contribution …
