These days, stop-start systems are a ubiquitous feature on new cars, and they're a reasonably simple system to comprehend. The mechanism shuts off the engine when your automobile stops, rather than letting it idle. When you release the brake, the engine restarts, and you can continue moving. Although it takes some getting used to—for the uninitiated, it might feel extremely strange for the engine to be entirely dead when all you've done is stop at the traffic lights—no there's denying that it is a sophisticated technology. It is intended to save fuel and lessen pollution, which its two main advantages.

If your engine is not running, it is not using gasoline or emitting pollution. Many would contend that these savings and cuts are so minimal as to be unimportant, yet even a little bit goes a long way, don't you think? The start stop battery is currently not as friendly as the battery, although it is intended to be more environmentally and financially friendly. In actuality, it makes the battery work much harder.

A typical automotive battery also referred to as an LSI (lighting, starting, ignition) battery, is made to start the car's motor reliably several times each day. The same task must be completed repeatedly throughout the day in a stop-start system. That takes effort. Furthermore, additional power is required in addition to the continual stop-start power. Everything else you want to use, including lights, air conditioning, entertainment systems, and a phone charger, gets its power from the battery while the engine is not working, just like in any other car.

A battery with more power is necessary for that kind of labor-intensive lifting. The start-stop batteries are used in this situation.

Types of Stop-start batteries

LiFePo4 Battery

It is clear that the lithium iron phosphate (LiFePO4) battery, commonly referred to as the LFP battery, has significant benefits over lead-acid batteries. Some examples are improved discharge efficiency, longer battery life, and the capacity to deep-cycle while maintaining performance.

ECM (Enhanced Cyclic Mat) battery:

It is also referred to as an Advanced Flooded Battery (AFB) or an Enhanced Flooded Battery (EFB), and it is made to satisfy the standards of entry-level stop-start technology. The typical lead-acid flooded technology used in LSI batteries has been improved with this battery.

It has increased cycle life, and deep cycle capabilities (which allow it to use more of its capacity before losing performance), and is more robust. It also provides for a more steady flow of electricity (the number of times it can be charged and discharged before it expires).

Absorbent Glass Mat (AGM) battery:

The most sophisticated application of lead-acid technology is where the acid is absorbed into fiberglass rather than staying as a liquid. The AGM battery has outstanding deep cycle qualities, is maintenance-free, has fast charging, high power output, improved cycle life, and can continue to produce high cranking power (the kind of power required to start an engine) even at low charge levels.

In electric and hybrid vehicles, regenerative braking systems enable the energy generated while braking using electric motors to be transferred to recharge the battery. AGM batteries can also be utilized with these systems. Although stop-start technology can be employed with either of these battery types, they are not interchangeable. AGM batteries can be used to replace ECM batteries; however, they should only ever be used in AGM-compatible automobiles. You shouldn't even think about using standard LSI batteries.
