From what I understood about lead acid batteries their capacity is related to the current drawn: the more current I draw from a battery, the less "effective" capacity I obtain, which mean... $begingroup$ That makes sense: as the battery discharges, the internal resistance increases and conversely the resistance of the load decreases in order …
LiFePO4 batteries typically require a specific charging algorithm, different from traditional lead-acid or other types of lithium batteries. This includes understanding the correct voltage limits, current rates, and the stages of charging specific to LiFePO4 chemistry.
High surge current: Lead-acid batteries can provide high surge current levels, making them suitable for applications that require a sudden burst of power. Recyclability: Lead-acid batteries are highly recyclable, with up to 99% of the battery material being Cons of
The discharge state is more stable for lead–acid batteries because lead, on the negative electrode, and lead dioxide on the positive are unstable in sulfuric acid. Therefore, the chemical (not electrochemical) decomposition of lead and lead dioxide in sulfuric acid will proceed even without a load between the electrodes.

Lead acid batteries have much shorter lifespans, charge and discharge less efficiently, and typically only have 50% usable capacity. LiFePO4 batteries used to be much more expensive. But, in recent years, lithium battery prices have plummeted to the point that budget LiFePO4 batteries are now cheaper than comparable lead acid batteries.
All lead-acid batteries discharge when in storage, so the right environment and active maintenance are essential. Sealed lead-acid batteries can be stored for up to 2 years, but it''s important to check the voltage and/or specific gravity and apply a charge when the battery falls to 70% state-of-charge.
