There are six cells to a 12 volt lead acid battery. A battery cell’s maximum ability to deliver current (amps). The positive plates contain a maximum amount of lead oxide and a minimum of lead sulphate and the negative plates contain a maximum of sponge lead and a minimum of sulphate. The electrolyte is at maximum specific gravity.
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
Lead acid batteries are fantastic at providing a lot of power for a short period of time. In the automotive world, this is referred to as Cold Cranking Amps. From GNB Systems FAQ page (found via a Google search):
The nominal capacity of sealed lead acid battery is calculated according to JIS C8702-1 Standard with using 20-hour discharge rate. For example, the capacity of WP5-12 battery is 5Ah, which means that when the battery is discharged with C20 rate, i.e., 0.25 amperes, the discharge time will be 20 hours.
Generally, the cut-off voltage is 10.5V for a lead-acid battery. Cranking Amps – It is the maximum current that a fully charged battery can supply for 30 seconds without any voltage drop. It is a parameter for measuring the strength of the battery.
This comes to 167 watt-hours per kilogram of reactants, but in practice, a lead–acid cell gives only 30–40 watt-hours per kilogram of battery, due to the mass of the water and other constituent parts. In the fully-charged state, the negative plate consists of lead, and the positive plate is lead dioxide.
How many amperes are there in 10 lead-acid batteries
Battery Reserve Capacity Explained. How much current can lead acid batteries safely supply? Cranking amps are the numbers of amperes a lead-acid battery at 32 degrees F (0 degrees C) can deliver for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12 volt battery).

How much current can lead acid batteries safely supply?
Cranking amps are the numbers of amperes a lead-acid battery at 32 degrees F (0 degrees C) can deliver for 30 seconds and maintain at least 1.2 volts per cell (7.2 volts for a 12 volt battery). A car actually doesn''t need 30 seconds, normally only a few seconds to start, except in very cold weather or other extreme situations.

How do I calculate how many batteries I need ...
When using lead-acid batteries it''s best to minimize the number of parallel strings to 3 or less to maximize life-span. This is why you see low voltage lead acid batteries; it allows you to pack more energy storage into a single string without going over 12/24/48 volts. There are many configurations that could work in the example above:

amperage
For the lead-acid battery, 55Ah would mean 1A for 55 hours. But lead acid batteries don''t last so long if run flat, so it''s best to assume only about half the rated capacity if you want a long life. The 550A is the maximum current that the battery can produce for just a few seconds - such as when starting a car. A battery does not store current.
