What is a safe max. discharge rate for a 12V lead acid battery?

Ideally the manufacturer supplies the discharge rates on the battery datasheet. A quick point: You mention you have a 12 V 2.4 A SLA (sealed lead acid) battery, but batteries are rated in amp-hours not amperes. Therefore I suspect you have a 12 V 2.4 Ah battery.

Characteristics of Lead Acid Batteries

In addition to the depth of discharge and rated battery capacity, the instantaneous or available battery capacity is strongly affected by the discharge rate of the battery and the operating temperature of the battery. Battery capacity falls by about 1% per degree below about 20°C. However, high temperatures are not ideal for batteries either as these accelerate aging, self …

What is lead acid battery thermal runaway?

Sealed Lead Acid (SLA) batteries all have a small amount of natural self-discharge simply from the behavior of the chemistry. This phenomenon is described in greater detail in our technical manual for SLA batteries. Natural self-discharge occurs at an extremely low rate – usually less than 3% per month. During a thermal runaway event, the ...
