Fragnance , i am not the big battery fun, but if not wrong in early days Pb batteries measured by applying load to fully charged batter and measuring voltage drop (internal impedance) . You should test each individual battery in pack - try to charge them to charged state (full charge voltage should be stated for each battery type) and apply load test. Also battery failures could be specific to particular battery type.

If wrongly used battery could get reduced capacity due to battery memory effect . In most cases it is possible to regain battery capcity by training - specific charge/discharge cycles.

Try to find battery type - cell characteristics (charged discharged voltages ..) should not be different among same battery types .
