Unlike LiPo batteries with have a maximum current rating, the lead acid battery only stated the "initial current", which is used for charging. The label stated not to short the battery. Hence, may I know what/how to find out the safe current to draw? How will the battery fail if I draw too much current (explode/lifespan decreased/?)? Thanks

Below is a chart I found of the changing resistance of a lead acid battery compared to state of charge, however, the charge acceptance is higher when it is discharged compared to when it is charged. How does this happen with a higher resistance that gradually gets lower? I'm also assuming a constant charging voltage from an alternator.
Lead acid batteries are actually the most complicated of all the common rechargeable battery types. They have lots of little quirks you have to pay attention to if you want to get the best possible life out of them. However, they do reasonably well in float service and are much cheaper than any lithium or nickel chemistry battery.
Many of the float charge and discharge voltages of lead-acid batteries in UPS power systems have been adjusted to their rated values at the factory, and the discharge current increases with the increase of the load. The load should be adjusted reasonably during use, such as control of the number of computers and other electronic equipment.

Invented by the French physician Gaston Planté in 1859, lead acid was the first rechargeable battery for commercial use. Despite its advanced age, the lead chemistry continues to be in wide use today. There are good reasons for its popularity; lead acid is dependable and inexpensive on a cost-per-watt base.
Cost is another important factor to consider when choosing a lead-acid battery. Here''s how the different types compare: Flooded Lead-Acid Battery: The most affordable option, but requires regular maintenance and can be messy. Sealed Lead-Acid Battery: More expensive than flooded batteries, but maintenance-free and leak-proof.
Sealed lead-acid batteries can ensure high peak currents but you should avoid full discharges all the way to zero. The best recommendation is to charge after every use to ensure that a full discharge doesn''t happen accidently.
Float charging works by providing a constant low-level current to the battery, just enough to keep it fully charged. The charging current is typically less than 5% of the battery''s capacity, and it is adjusted based on the battery''s temperature and state of charge. The charging voltage is also adjusted to prevent overcharging and to compensate for changes in the …
