Lead acid batteries can be divided into two distinct categories: flooded and sealed/valve regulated (SLA or VRLA). The two types are identical in their internal chemistry (shown in Figure 3). The most significant differences between the two types are the system level design considerations.
Lead acid batteries have been around for more than a century. In the fully charged state, a 2V electric potential exists between the cathode and the anode.
Lead Acid versus Lithium-ion White Paper Lead acid batteries can be divided into two distinct categories: flooded and sealed/valve regulated (SLA or VRLA). The two types are identical in their internal chemistry (shown in Figure 3). The most significant differences between the two types are the system level design considerations.
Partial charging as a function of cycle for lead-acid cells charged with constant, standard wind or low-frequency wind protocols. The second trend we notice is that the batteries accept more charge at a constant rate than variable, and at a 1 Hz frequency than 0.1 Hz.
Typical lead-acid battery packs are sized for only 50% DOD, but a LFP pack could operate over the full range without accelerating aging and could be sized without needing to account for large future capacity loss. The LFP electrode is also much more stable and therefore safer than LCO-NMC and LCO cells.
The initial lead-acid cell capacity ranged from 3.50 to 3.58 Ah, with the exception of one 3.68 Ah cell which remained an erratic outlier for the remainder of the cycling tests and is not considered in the final analysis. The capacity of the LFP cells ranged from 2.0 Ah to 2.08 Ah.
CONCLUSIONS The purpose of this work was to revisit Peukert’s equation and examine its validity with modern lead acid and lithium batteries. Experimental data suggests that Peukert’s exponent for individual lead acid batteries is not constant but it is a function of battery capacity and discharge current.

Lead Acid versus Lithium-Ion WHITE PAPER. 3.2 Rate Performance . When determining what capacity of battery to use for a system, a critical consideration for lead acid is how long the system will take to discharge. The shorter the discharge period, the less capacity is available from the lead acid battery.
