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):
OCV, impedance and conductance readings were measured and each battery was “dead short” tested using the test method described above. In theory, with a perfect conductor you are looking at over 2000 Amps. With their test, they saw 1700 Amps. And these are just 33 Amp Hour batteries, small compared to most cars. These are UPS batteries!
The motor can draw quite a lot of current when stalling and I am worried of overdischarging the lead acid battery. 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.
Assuming you have a 12V battery that is in good condition, it can supply up to 30 amps of current. The amount of current that a battery can provide depends on its size and capacity. A larger battery will be able to provide more current than a smaller one. How Batteries are Rated?
The higher the internal resistance, the lower the maximum current that can be supplied. For example, a lead acid battery has an internal resistance of about 0.01 ohms and can supply a maximum current of 1000 amps. A Lithium-ion battery has an internal resistance of about 0.001 ohms and can supply a maximum current of 10,000 amps.
A lead acid battery can provide up to 2,000 amperes (A) of current while a lithium-ion battery can only provide about 700 A. The amount of current that a battery can provide also decreases as the temperature gets colder.

This is the primary factor that limits battery lifetime. Deep-cycle lead-acid batteries appropriate for energy storage applications are designed to withstand repeated …
The lifetime of a lead acid battery, before it wears out, is strongly related to its depth of discharge. That battery rates 260 cycles at 100% DOD, ie to 1.75v. You can double that lifetime if you only discharge to 50%, and x5 if you …
Now that you have seen the estimated amp hours of most car batteries here on the table, you can easily see that 10% or less for most car batteries is going to be in the 2-amp to the 7.5-amp …
In practical terms, a 12V, 35 Ah lead-acid battery can power a device drawing 1 amp for approximately 35 hours under ideal conditions. Conversely, if a device draws 3 …
However, for most standard lead-acid or deep-cycle batteries, a general rule of thumb is that a fully charged 12-volt battery typically has an ampacity around 50-65 amps. …
A typical 12-volt car battery will have a capacity of 48 amp-hours (Ah). That''s the amount of energy it can store, and it tells you how long a battery can provide power at a given …
Cold-cranking amps measure how many amps the jump starter puts out for 30 seconds at 0 °F (-18 °C); while keeping the current of the battery at 7.2 volts. ... If you live in a …
The lead-acid battery is the most common type, and it consists of six cells, each producing about 2.1 volts. Together, these cells provide 12 volts, which is standard for …
lead-acid battery charging current limit. The maximum charging current for a lead-acid battery is 50% and 30% for an AGM battery. But recharging your battery at this much high …
Another important indicator is the battery''s voltage. A fully charged lead-acid battery should have a voltage of around 12.8 volts. If the voltage drops below 12.4 volts, the …
Figuring out how many amps are in a 12-volt battery can be confusing. But a typical 12-volt car battery has a capacity of around 48 amp-hours. Batteries can have different amp-hour ratings, so choosing one that …

The recommended charging voltage for a lead acid battery is between 2.25V and 2.30V per cell. For a 12V battery, this translates to 13.5V to 13.8V. How many amps …
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 …
For lead-acid batteries, the ideal charging current is typically recommended to be between 10% to 30% of the battery''s amp-hour (Ah) capacity. The Battery Council …
Most lead-acid batteries have six cells, each with a nominal voltage of 2.1 volts, which adds up to a total battery voltage of 12.6 volts. Lithium-ion batteries, on the other …
The Ampere-hour (Ah) rating is key for car batteries. It shows how much power a battery can give over time. Most cars have a 48 Ah battery, but it can range from 40 to 110 …
