Start Stop Car Battery: Lead-acid Battery vs. Lithium-ion Battery

-

In 1859, French physician Gaston Planté pioneered the commercial use of lead acid — the first rechargeable battery. In recent years, lead-acid batteries have been optimized in numerous applications for its reliability and inexpensive cost-per-watt base but there remain certain new shortcomings facing the lead-acid battery manufacturers —an increase in the amount of faulty modes.

Types of Lead-acid Batteries

●Batteries with flooded or excess electrolyte.

●Low-maintenance lead-acid batteries with a large excess of electrolyte.

●Batteries with immobilized electrolyte and a pressure-sensitive valve usually referred to as absorptive glass-microfibre (AGM) valve-regulated lead-acid (VRLA) batteries.

 

Advantage

Disadvantages

●Inexpensive and simple to manufacture; low cost per watt-hour

●Low self-discharge; lowest among rechargeable batteries

●High specific power, capable of high discharge currents

●Good low and high temperature performance

●Low specific energy; poor weight-to-energy ratio

●Slow charge; fully saturated charge takes 14-16 hours

●Must be stored in charged condition to prevent sulfation

●Limited cycle life; repeated deep-cycling reduces battery life

●Flooded version requires watering

●Transportation restrictions on the flooded type

●Not environmentally friendly

Overview of Lithium-ion Batteries

Lithium-ion began to surface in the 1970s, yet these immediate batteries are not rechargeable. Thus in the 1980s, rechargeable versions were manufactured. Nowadays, it's the most common battery in commercial use. Lithium is lightweight in contrast to other metals and the highest density per kilogram. Therefore, lithium is the most ideal for batteries since it contains significant amounts of energy and has the greatest electrochemical potential.

How to Charge a Deep Cycle Battery in a Car?

Deep cycle batteries   are designed to provide a continuous flow of power over an extended period. Unlike starting batteries that deliver a quick burst of energy to start an engine, deep cycle batteries are built to withstand deep discharges and subsequent recharges. They are commonly used in car, marine, golf cart, and renewable energy applications. Steps to Charge a Deep Cycle Battery in a Car Step 1: Safety precautions Before attempting to charge a deep cycle battery, it's essential to take safety precautions. Make sure you are in a well-ventilated area, wear protective gloves and safety goggles, and keep any open flames or sparks away from the battery. Step 2: Assess the battery condition Before charging, inspect the battery for any signs of damage or leaks. Ensure the battery terminals are clean and free from corrosion. If you notice any issues, it's advisable to address them before proceeding with the charging process. Step 3: Determine the battery's state of charge T...

Lithium batteries replacing sealed lead acid in float applications

  It is extremely typical for lithium batteries to be positioned in an application where a shantytown battery used to be maintained on a floating fee. There has been some problem, whether this is secure for lithium batteries. It is usually appropriate to make use of a basic continuous voltage SLA charger with our lithium batteries, as long as it abides by particular requirements. As a side note, some clever or multi-stage shanty town battery chargers have an attribute that detects an open-circuit voltage (OCV). An over-discharged lithium battery that is in defense mode will have an OCV of 0. This type of charger would presume this battery is dead as well as would not attempt to charge it. A battery charger with a lithium setup will attempt to recuperate or "awaken" an over-discharged lithium battery. Long term storage space If you need to maintain your batteries in storage for a prolonged duration, there are a few things to think about as the storage space needs are various f...

How Does Car Start/Stop Technology Work?

-

Starting a car eats up more fuel than letting it idle for an hour. While cold starts tend to suck down a fair amount of gas when you first turn the ignition key, it’s the exact opposite when the engine is at optimal running temperature. This is why so many new car manufacturers are incorporating start/stop technology into their automobiles. The Society of Automotive Engineers ran a study that found that modern stop/start systems actually help increase fuel economy by over eight percent when running in heavy traffic. Over time, this can add up to a tremendous amount of fuel—and money—savings. Read on to learn more about how to stop/start technology works and one critical component of that system that uses more power than you may realize.   Start/Stop Technology While each car manufacturer has its own proprietary system, they all work very similarly. When you apply the brakes, and your car comes to a complete stop, the ECU cuts both fuel and spark, thereby instantly shuttin...
