LiFePO4 Batteries In Series Vs Parallel: What Are The Differences?

Connecting LiFePO4 battery in parallel is when you connect two or more batteries together to increase the amp-hour capacity. With a parallel battery connection the capacity will increase, however the battery voltage will remain the same.

For example, if you connect four 12V 100Ah batteries in parallel, you would get a 12V 400Ah LiFePO4 battery system.

When connecting batteries in parallel, the negative terminal of one battery is connected to the negative terminal of the next and so on through the string of batteries. The same is done with positive terminals.

Batteries connected in parallel must be of the same voltage, i.e. a 12V battery can not be connected in parallel with a 6V battery. It is best to also use batteries of the same capacity when using parallel connections.

Connecting batteries in series is when you connect two or more batteries together to increase the battery systems overall voltage, connecting batteries in series does not increase the capacity only the voltage.

For example if you connect four 12V 200Ah batteries you will have a battery voltage of 48V and battery capacity of 200Ah.

To connect a group of batteries in series you connect the negative terminal of one battery to the positive terminal of another and so on until all batteries are connected. You would then connect a link/cable to the negative terminal of the first battery in your string of batteries to your application, then another cable to the positive terminal of the last battery in your string to your application.

To configure batteries with a series connection each battery must have the same voltage and capacity rating, or you can potentially damage the batteries. For example you can connect two 6Volt 10Ah batteries together in series but you cannot connect one 6V 10Ah battery with one 12V 20Ah battery.

What Is The Average Life Of a 12-Volt Car Starter Battery

Understanding the Lifespan of a 12-Volt Car Starter Battery

When it comes to maintaining your vehicle, understanding the lifespan and maintenance of your car’s battery is crucial. The average life of a 12-volt car starter battery varies but typically ranges from 3 to 5 years. However, several factors can influence this, from environmental conditions to usage patterns. In this article, we’ll dive deep into what affects the life of your car battery, how you can extend it, and the benefits of choosing Himax Electronics for your battery needs.

Factors Affecting the Life of a 12-Volt Car Starter Battery

The lifespan of a car starter battery is impacted by numerous factors:

 

Climate: Extreme temperatures can significantly shorten a battery’s life. Heat accelerates corrosion inside the battery, while cold can reduce its capacity to hold a charge.

Driving Habits: Short trips that don’t allow the battery to fully charge can shorten its life. Frequent starting and stopping put more strain on the battery than longer, consistent runs.

Vehicle Demands: Modern vehicles with advanced electronics, such as GPS, heated seats, and multimedia systems, draw significant power from the battery, even when the engine isn’t running.

Maintenance: Poor maintenance can lead to faster deterioration. A dirty or corroded battery can cause a drop in performance and lifespan.

Battery Quality: High-quality batteries, although sometimes more expensive, generally offer longer life and better performance.

How to Extend the Life of Your Battery

Extending the life of your battery not only saves money but also reduces the inconvenience of unexpected battery failures:

 

Regular Maintenance: Check your battery regularly for signs of wear or damage. Clean the terminals, tighten connections, and ensure that the battery is securely mounted to prevent vibration damage.

Keep It Charged: Maintain the battery charge by driving your car regularly. If you use your car infrequently, consider using a battery maintainer to keep the battery charged.

Manage Electrical Load: When your engine is off, try to minimize the use of car electronics that draw power from the battery.

Check the Charging System: Ensure your car’s charging system is functioning properly. Overcharging or undercharging can significantly affect your battery’s lifespan.

Temperature Control: Whenever possible, park your vehicle in a garage to protect the battery from extreme temperatures.

Testing Your Battery

It’s important to test your battery’s health regularly:

 

Voltage Check: Use a multimeter to check the voltage. A fully charged battery should read at least 12.6 volts.

Professional Load Test: Annually, have a professional perform a load test to assess the battery’s ability to hold charge under load.

Replacing Your Battery

Knowing when to replace your battery can prevent you from being stranded with a dead battery. Signs that you might need a new battery include slow engine crank, issues with electrical components, or an old battery (over 3 years).
