$begingroup$ Your question is unclear, you probably mean not only using them together (different batteries used separately in the same device, that''s OK) but you also want to connect them together (in parallel or series). That last one is a big NO.NEVER connect batteries with different chemistries together. For example, the charging requirements of Lead …

The Fig. 6 is a model used to explain the ion transfer optimization mechanisms in graphene optimized lead acid battery. Graphene additives increased the electro-active surface area, and the generation of −OH radicals, and as such, the rate of −OH transfer, which is in equilibrium with the transfer of cations, determined current efficiency.
If the lead acid batteries you will use are of the starter type (and not of the deep cycle type, as used e.g. in UPSs) they are designed to provide current pulses that are even hundreds times greater than their normal current rating (e.g. a 50A rated battery could provide 1000A pulses for a couple of seconds). This is a problem with LiIon cells, which usually can''t …

Overcharging: Lithium batteries are sensitive to overcharging, which can cause overheating, gas buildup, and even thermal runaway. This can lead to battery damage, reduced capacity, or, in extreme cases, fires or explosions. Undercharging: On the other hand, a lead acid charger may not provide enough voltage or current to fully charge a lithium battery.
