Many that have golf carts, small EV's, RV's, or solar power banks for homes have a number of 12V lead acid batteries to maintain and this circuit will help protect your investment while not using these batteries. When stored, batteries will self discharge, and if left for too long, will self-discharge to a damaging level.
The terminal voltage of the Lead Acid battery should be with in the range of 12.5 to 13.5 volts. If the battery voltage reduces below 10 volts for long period, battery will not accept any charging current. Similarly if the terminal voltage exceeds above 14 volts, battery will be destroyed.
... lead-acid battery, a voltage is produced when reaction occurs between the lead electrodes and sulfuric acid and water electrolytes . The schematic view of lead-acid battery is depicted in Figure 2.
With the above component values it will cut out at 11.2V and re-activate at 12V, which is good for most sealed lead acid batteries. There is also second comparator – this is purely acting as a logic inverter, because I needed a negative logic output. If you don't need it, leave it out.
A low voltage cutoff circuit is an electronic circuit that monitors the voltage of a battery and disconnects the load when the voltage drops below a predetermined threshold. This prevents the battery from being over-discharged, which can lead to reduced performance, shorter lifespan, and even permanent damage.
