Charging characteristics of lithium iron phosphate batteries
The full charge open-circuit voltage (OCV) of a 12V SLA battery is nominally 13.1 and the full charge OCV of a 12V lithium battery is around 13.6. A battery will only sustain damage if the charging voltage applied is significantly higher than the full charge voltage of the battery. This means an SLA battery should be kept below. It is very common for lithium batteries to be placed in an application where an SLA battery used to be maintained on a float charge, such as a UPS system. There has been some concern, whether this is safe for lithium batteries. It is. If you need to keep your batteries instorage for an extended period, there are a few things to consider as thestorage requirements are different for SLA and lithium batteries. There. It is always important to match your charger to deliver the correct current and voltage for the battery you are charging. For example, you wouldn't use a 24V charger to charge a 12V battery.

Most lead-acid batteries charge at a constant 14 4 volts, so charging several in parallel is really just a charge-current issue. If the charger cannot supply enough current it will likely lower the charge voltage to protect itself.
Can a lead acid battery be connected in parallel?
In theory it is OK to connect them in parallel with two conditions: Each battery must be in a state where it can be voltage charged. This is fine for lead acid batteries unless they are very run down. Very discharged lead-acid batteries have to be charged with fixed current until they get to a minimum voltage, then they can be voltage charged.
Can You charge lead acid batteries together?
Charge them separately with a good (3 or more stage) battery charger and see if they hold their charge for a day (setlling at about 12.6 or 12.7 V), or if they charge at all. If they do, you can probably safely charge them together. There are always risks involved when charging lead acid batteries. Keep them well ventilated and fused.
What voltage should a lead acid battery be charged at?
Lead acid batteries will not be properly charged at just 13.8 V. All (not some) lead acid batteries I know need a “bulk” charge voltage over 14 Volts (look up the datasheet of any lead acid battery to confirm this). 13.8 V is just to maintain the charge (“float voltage”).
