Lead–Acid Batteries
This type of lead–acid battery is designed to have high power density, but it has low total energy content and is not designed for applications that require energy delivered for long periods of time. It can also not handle deep discharge. The car battery normally operates with depth-of-discharge (DoD) of only 20%.

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.
BU-403: Charging Lead Acid
Hi, I am making an adjustment to my house alarm so the 2 external siren boxes are powered by one lead acid battery (using in total about 25m of cable). Previously the siren boxes each ran on 6 D cells. I have a 6v 4ah lead acid battery, and a 3 stage (with float) 750ma charger which will be connected permanently to the battery.
What''s the difference between a normal car battery and a deep …
A deep cycle battery can provide a surge when needed, but nothing like the surge a car battery can. A deep cycle battery is also designed to be deeply discharged over and over again (something that would ruin a car battery very quickly). To accomplish this deep discharge, a deep cycle battery uses thicker lead plates.

50% Depth of Discharge for Lead Acid Battery
During these 7 hrs of recharge, the battery would only be at 80% SoC. When the power-cut occurs, the battery will start to discharge further from the 80% SoC whereas ideally we would have liked the battery to discharge from 100% SoC. Thus the battery didn''t get enough time to recharge to 100% which will accelerate the sulfation …
