Along with the maximum continuous power of the motor, this defines the top sustainable speed and acceleration of the vehicle. • Maximum 30-sec Discharge Pulse Current –The maximum current at which the battery can be discharged
On lead-acid batteries, there is a parameter called "maximum initial current" which is generally written on it. I have added some pictures of it at the end of the question. My confusion is how to interpret it? Is it: The battery can demand more but I should maintain constant current below that limit. OR. The battery will never draw more than
For example, a fully charged 12V lead-acid battery typically has an OCV of 12.6 to 12.8 volts, while a 50% SOC corresponds to around 12.0 volts. Understanding the SOC-voltage correlation helps. There is so much about different battery voltages and how their state of charge relates to their voltage levels.
4. Measuring Maximum Current – having estimated the maximum current it is good practice to check this data against the actual cell. It is advisable to approach this value rather than push the cell too far and damage it. All of these measurements are going to take time as the maxumum current is dependent on lots of parameters.
Understanding lead acid battery discharge levels is essential for users who rely on these batteries for various applications. The charging process of lead acid batteries involves applying an external current to reverse the chemical reactions that occur during discharge. Some manufacturers may advise a maximum discharge of 80% for

If you were to stand the vehicle then the trickle would be a must in order to maintain the battery logevity as long periods of discharge are not welcomed in a lead acid battery. The rated capacity could be measured and this would typically be at a much lower C Rate probably 0.2 - 0.5C at 20 degress.
I have read many recommendations that a 12 V lead acid battery should not be discharged to a voltage lower than 10.5 V. Why is this. Does it have to do with the acidity of the electrolyte which may determine the temperature at which the electrolyte freezes? Or at lower voltage levels does the power demand increase current flow to a harmful level?

Avoiding the full discharge of a lead acid battery is crucial for maintaining
Lithium Battery Cycle Life vs. Depth Of Discharge. Most lead-acid batteries experience significantly reduced cycle life if they are discharged below 50% DOD. LiFePO4 batteries can be continually discharged to 100% DOD and there is no long-term effect. However, we recommend you only discharge down to 80% to maintain battery life. Lithium Battery
Victron VRLA batteries have exceptional discharge recovery, even after deep or prolonged discharge. Nevertheless repeatedly deep and prolonged discharge has a very negative effect
Although this varies cycle to cycle, the maximum depth of discharge for lead acid batteries is typically at or below 50%. The cycle life of lead acid batteries is highly dependent on the State of Charge (SoC) that the battery is cycled at.
First if all when I searched about discharge rate of this kind of battery I found this "The sealed lead-acid battery is rated at a 5-hour (0.2) and 20-hour (0.05C) discharge".
So for example, a lead acid battery might have a capacity of 600Ah at a discharge current of 6A. With a higher discharge current, of say 40A, the capacity might fall to 400Ah. In other words, by increasing the discharge current by a factor of about 7, the overall capacity of the battery has fallen by 33%.
Discharge rate can usually exceed charge rate if required. Recommended operating range 10 to 25°C. Lead acid batteries are highly affected by temperature. The lifetime of lead acid batteries is cut in half for every 10°C rise in operating temperature over 25°C, due to rapid increases in the corrosion rate of the internal components of the battery.
