Battery imbalance
The normal imbalance for a 12v lead batteries is less than 0.5v when charged and way less (less than 0.1v) in intermediate state of charge. p.s. I expect brand-new lead batteries to be of equal (near-100%) state of charge. Getting two unbalanced batteries means something is not absolutely OK.

Maintaining Your Lead-Acid Battery
Sealed lead acid batteries need to be kept above 70% State of Charge (SoC) during storage. If you''re storing your batteries at the ideal temperature and humidity levels, then a general rule of thumb would be to recharge the batteries every six months. However, if you''re unsure, you can check the voltage to determine if a recharge is necessary.
Wiring Balance Leads For Balancer And BMS
Over time as a lithium-ion battery is used, the cells age at different rates. The BMS in the lithium-ion battery will shut the battery off when any one cell group goes past a certain threshold. When a cell group is out of balance, it can cause energy to be wasted because it can cause the BMS to shut off sooner than it otherwise would have.
An Eco-balance of a Recycling Plant for Spent Lead–Acid Batteries
This study applies Life Cycle Assessment (LCA) methodology to present an eco-balance of a recycling plant that treats spent lead–acid batteries. The recycling plant uses pyrometallurgical treatment to obtain lead from spent batteries.

Approaching proper LFP charging with Lead-Acid chargers; 1. Correct/Standard charge model for a LFP Cell ... The ideal (and most time consuming) way to do initial top-balance for a battery will always be to take each Cell, subject it to standard charge model as mentioned above and then connecting all such cells to yield a top-balanced battery ...
Battery balancing
The individual cells in a battery pack naturally have somewhat different capacities, and so, over the course of charge and discharge cycles, may be at a different state of charge (SOC). Variations in capacity are due to manufacturing variances, assembly variances (e.g., cells from one production run mixed with others), cell aging, impurities, or environmental exposure (e.g., some cells may be subject to additional heat from nearby sources like motors, electronics, etc.), and c…
Why Lead batteries do not need balancing?
In fact, sealed lead acid batteries need very strong balancing on every charge cycle --- in order of 100 to 1000 times stronger than what li-ion needs. 6-cell (12V) SLA is the biggest usable unit that can balance itself through the slow recombination of H2 and O2, but even then you need to regulate voltage and current very carefully.

BU-403: Charging Lead Acid
The lead acid battery uses the constant current constant voltage (CCCV) charge method. A regulated current raises the terminal voltage until the upper charge voltage limit is reached, at which point the current drops due to saturation. The charge time is 12–16 hours and up to 36–48 hours for large stationary batteries.
