Before directly jumping to know the concepts related to lead acid battery, let us start with its history. So, a French scientist named Nicolas Gautherot in the year 1801 observed that in the electrolysis testing, there exists a minimal amount of current even when there is a disconnection of the main battery.
This circuit prevents over-discharge of a lead-acid battery by opening a relay contact when the voltage drops to a predetermined voltage (lower voltage threshold). When the battery is recharged to a second predetermined higher voltage (upper voltage threshold), the relay contact automatically re-closes and power again flows to the load.
Lead Acid Battery Example 1. A lead-acid battery has a rating of 300 Ah. Determine how long the battery might be employed to supply 25 A. If the battery rating is reduced to 100 Ah when supplying large currents, calculate how long it could be expected to supply 250 A. Under very cold conditions, the battery supplies only 60% of its normal rating.

The idea seems to be to draw power from the battery at a steady rate (hence the L2-C4 decoupling circuit) and release it back to the battery in pulses. [EDIT: if you want to redesign the circuit around an Arduino, I''d design it around an N-channel logic level mosfet, which means inverting the sense of the mosfet/L1/L2/C4 combo.

Usually the capacity of a battery is quoted at a C/20 discharge rate. So an 12 amp hour battery sealed lead acid battery will actually put out a steady 0.6 amps for 20 hours. However, if you discharge the same battery at 12 amps, you would expect to run an hour, but you will only last for 22 minutes.
