How to Choose the Right Start-Stop Car Battery

Start Stop technology places a lot of demand on the battery and requires a specially formulated one. These batteries are often made with maintenance free AGM technology and have increased cycle capability for the frequent charge and discharge of the battery.

A normal lead acid battery cannot deal with this increased energy demands and will deteriorate quickly. It is therefore essential that the correct battery is used.

Enhanced Flooded Battery (EFB)

Conventional flooded batteries are a convenient way to start your car and power your radio. However, as we add more bells and whistles to our cars the power demands of these devices can require a higher-performing battery.

That’s where the EFB or enhanced flooded battery comes in, which is an upgraded version of standard flooded technology. These batteries feature a movable cover that allows you to add distilled water to adjust the electrolyte concentration. This helps to improve cyclic durability for the battery and can increase its lifespan to up to 3 to 5 times longer than conventional flooded products.

They also feature designs that increase thermal stability for use in engine compartments and hot climates, as well as high-density plates made from thicker lead for improved cyclic performance. Additionally, they’re designed to support the high number of engine starts and long periods of engine-off operation found in vehicles with Stop-Start technologies.

These batteries are ideal for drivers who have a tough driving schedule and a vehicle with multiple accessories installed. They also help you get more from your vehicle with regenerative braking and passive boost capabilities. With more than 500% increase in the number of electrical devices in modern cars, it’s important to understand your battery’s abilities and choose the right one for your car’s power needs.

Absorbent Glass Mat (AGM)

AGM batteries have made a big impression in recent years. Also known as dry cells, AGM batteries are maintenance-free and powerful alternatives to traditional wet cell batteries. They’re well-suited for start-stop vehicles that require a lot of power to operate electronic systems for long periods of time.

The key difference between an AGM battery and a standard wet lead acid battery is the electrolyte. While a wet cell battery has liquid electrolytes, an AGM battery contains electrolyte inside thin fiberglass mats that are start-stop car battery compressed and welded together. The glass mats absorb the electrolyte mixture, making the battery non-spillable and allowing it to be shipped without hazardous materials restrictions.

AGM car batteries also have thicker plates than standard SLA batteries, which results in less active material shedding and longer battery life. They also offer a higher charging rate than conventional wet cell batteries, although overcharging can affect their lifespan.

AGM batteries are commonly found in electric vehicle service, uninterrupted power supply systems and even off-grid renewable energy applications such as wind and solar systems. They can withstand high electrical loads and are highly versatile. They can be recharged at a faster rate than flooded lead acid batteries, though overcharging is still a concern. They also have a smaller physical footprint than other types of batteries, so they can be fitted into tight spaces.

ECM (Electronic Control Module)

The ECM is the heart of your engine’s operation, monitoring a host of sensors and inputs that allow it to optimize your car’s performance. From fuel-to-air ratios to ignition timing and emissions control systems, your ECM manages all the moving parts to help ensure that you get optimal power while maintaining emissions levels and ensuring safety.

It also helps your vehicle meet compliance standards, by tracking and regulating exhaust gas systems such as diesel particulate filters (DPFs) and selective catalytic reduction systems. By logging emissions data and monitoring conditions such as temperature, pressure and chemical composition of the exhaust, your ECM can automatically adjust operations like fuel injection and ignition timing to reduce pollutants.

Finally, the ECM helps make sure your car is safe to drive by constantly monitoring and managing braking system functions. It determines if a wheel is about to lock up and modulates the brake pressure accordingly, helping maintain maximum road safety. opzv battery suppliers It also monitors and manages other safety systems, such as airbags and seatbelt pre-tensioners.

If something goes wrong, your ECM records diagnostic trouble codes that can be retrieved with the use of professional tools and code charts. This allows mechanics to quickly identify and fix problems, reducing time and expense for you and your dealer. This is particularly beneficial for fleet vehicles, as it keeps your entire crew on the road while minimizing the need for costly downtime.

Conventional Battery

Conventional lead acid batteries have been the industry standard for decades and provide powerful cranking energy. However, they are prone to damage from repeated deep discharges and short cycle use. This is especially true for start-stop applications that demand frequent short bursts of power to activate engines and electrical accessories.

Conventional flooded batteries are available in a range of sizes with different voltages to match your vehicle’s needs. They are also often referred to as maintenance free or sealed lead acid (SLA) batteries. These are not leaking and do not require the addition of water but they do need to be fully charged when first installed in your car.

If the battery electrolyte level drops after the initial charge, you can add distilled water/demineralized water to the battery at the filler plugs. However, normal tap water/battery water should not be used because it contains minerals that can damage battery plates.

When a conventional battery recharges, electricity splits the water in the electrolyte into hydrogen and oxygen, which mostly gets reabsorbed back into the electrolyte but some escapes through vents in the case. This water loss is why regular batteries need to be occasionally topped up with distilled water. AGM batteries have a one-way valve that regulates how much oxygen and hydrogen can escape when the battery charges, making them less prone to water loss. This is why they are the better choice for start-stop applications.
