Charging three lead acid batteries in parallel with a single 14V
Charging Lead-Acid batteries in parallel is not a problem, but a larger battery charger that feeds up to 6A, when equally divided by your 3 batteries of 9Ah, would give 2A/battery, in the best case. Sealed-LA batteries maximum charging current usually is 10-20% of rated capacity. For a 9Ah, I_max = 1A ~ 2A.

I knew about voltage safety and making sure the batteries matched/equalized charge, etc. At any rate, I''ll probably use a larger AH battery and an inverter (probably more economical), or if I can get the batteries cheap enough, charge them in parallel and run them in series using relays to switch which "mode" they''re in.
6 FAQs about [Charge the lead-acid batteries in series and parallel]
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 a lead-acid battery in parallel?
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.
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”).
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.
How do I charge a sealed lead acid battery?
Power Sonic recommends you select a charger designed for the chemistry of your battery. This means we recommend using a sealed lead acid battery charger, like the the A-C series of SLA chargers from Power Sonic, when charging a sealed lead acid battery. Sealed lead acid batteries may be charged by using any of the following charging techniques:
