Starter Batteries vs Deep Cycle Batteries, What are the Differences?
Info
March 21, 2023 By 0 Comments

Starter Batteries vs Deep Cycle Batteries, What are the Differences?

We delve into the critical distinctions between starter batteries and deep cycle batteries, empowering you to make informed decisions based on your energy needs.

What is a Starter Battery?

A starter battery, also referred to as a vehicle battery, serves a crucial role in starting engines with a powerful surge of electricity. Typically, these batteries are designed to provide a short burst of energy to crank the engine, after which the alternator takes over to recharge the battery. The energy discharge during engine start-up typically only depletes the battery by a minimal 1% to 3%. This minimal discharge ensures that starter batteries maintain their capacity for frequent and reliable engine starts over an extended period.

Ideal Uses for Starter Batteries

Starter batteries are ideal for:

  • Gasoline-powered vehicles
  • Motorcycles
  • Small engines where quick bursts of power are essential

Redway Power Lithium Starter Batteries: Innovation in Starting Power

At [Your Company Name], we offer Redway Power Lithium Starter Batteries, revolutionizing vehicle power solutions with advanced lithium technology. Unlike traditional lead-acid batteries, our lithium starters deliver superior performance and durability. They are specifically engineered to provide maximum cranking power with minimal weight, ensuring reliable starts even in harsh conditions.

Understanding Deep Cycle Batteries

Unlike starter batteries, deep cycle batteries are designed to provide sustained power output over extended periods. These batteries are ideal for applications requiring continuous and reliable energy, such as marine, solar storage, and home backup systems. Deep cycle batteries can withstand frequent deep discharges without significantly impacting their lifespan, making them a reliable choice for off-grid and renewable energy solutions.

Benefits of Redway Power Lithium Deep Cycle Batteries

  • Offer significantly longer cycle life (2000–5000 cycles)
  • Allow deep discharges up to 10% of capacity without damage
  • Provide up to twice the usable power compared to conventional lead-acid batteries
  • Weigh half as much, making them ideal for applications where weight savings are critical

Moreover, our lithium iron phosphate (LiFePO4) chemistry ensures exceptional efficiency in storing solar energy, achieving up to 96% energy utilization compared to 76% with sealed lead-acid batteries.

Applications of Redway Power Lithium Deep Cycle Batteries

We specialize in large capacity 12 Volt lithium batteries ranging from 10 amp-hours to 170 amp-hours and beyond. Our batteries are tailored for:

  • Solar energy storage
  • Marine and RV applications
  • Home backup power systems

Dual Purpose Batteries: Versatility and Performance

Dual purpose batteries combine the characteristics of both starter and deep cycle batteries, offering flexibility and high performance. These batteries are designed to provide both cranking amps for engine starting and deep cycle capabilities for continuous power supply.

Redway Power Lithium Dual Purpose Batteries

Our dual purpose batteries, such as the 12V 135Ah model, deliver:

  • 135 amp-hours of deep cycle capacity
  • 1000 cold cranking amps for reliable engine starting

Comprehensive Guide to Charging Lithium and LiFePO4 Batteries

Welcome to our ultimate guide on charging lithium and LiFePO4 batteries. This article provides detailed instructions, best practices, and essential knowledge to ensure your batteries are charged efficiently, safely, and effectively. Our goal is to help you maximize the lifespan and performance of your lithium batteries, whether you are using them in vehicles, solar power systems, or other applications.

Understanding Lithium and LiFePO4 Batteries

What Are Lithium and LiFePO4 Batteries?

Lithium-ion batteries are a type of rechargeable battery commonly used in various electronic devices and vehicles. Lithium Iron Phosphate (LiFePO4) batteries are a specific subtype of lithium-ion batteries known for their safety, thermal stability, and longer lifespan.

Charging Lithium and LiFePO4 Batteries

Do You Need a Special Charger for Lithium Batteries?

Yes, lithium and LiFePO4 batteries require a specific charger designed to provide the appropriate voltage and charging profile. Standard lead-acid battery chargers are not suitable as they do not deliver the required higher voltage and precise control needed for lithium batteries.

Recommended Voltage for Charging

  • LiFePO4 Batteries: Charge at 14.4 – 14.8 Volts.
  • NMC (Nickel Manganese Cobalt) Batteries: Similar voltage range as LiFePO4.

Using a charger that delivers these voltages ensures that your lithium batteries reach their full capacity and perform optimally. Lead-acid chargers typically only charge lithium batteries to 60-80% of their capacity.

Choosing the Right Charger Brand

For optimal performance, we recommend using chargers specifically designed for LiFePO4 batteries. Some reliable brands include:

  • Redway Power Lithium Chargers: Provide optimal voltage and undergo rigorous quality control.
  • Victron Energy: Known for their efficient and reliable chargers.
  • Battle Born: Offers robust chargers designed for LiFePO4 batteries.

Charging with Solar Panels

Direct Connection for Small Panels

For solar panels less than 60 watts, you can directly connect the panel to the battery. The Battery Management System (BMS) will prevent overcharging.

Using a Solar Charge Controller

For larger solar setups (100 watts or more), a solar charge controller is essential. The controller optimizes the voltage and increases charging efficiency. Recommended models include:

  • Victron SmartSolar MPPT 75/15
  • Renogy Rover MPPT

Solar Panel Size for Charging

Here’s a size chart for recommended solar panel capacities to charge different lithium batteries:

Battery Size (Ah) Recommended Solar Panel Capacity (Watts) Solar Charge Controller
12V 7Ah 20 None
12V 10Ah 50 None
12V 23Ah 50 None
12V 54Ah 100-200 15 Amp MPPT
12V 100Ah 100-200 15 Amp MPPT
12V 200Ah 200 15 Amp MPPT
12V 400Ah 300 15 Amp MPPT

Charging with Onboard Chargers

Onboard chargers can be used if they have a lithium setting or can be set to 14.4V. For marine or AGM onboard chargers without a lithium setting, they will not fully charge the battery.

Charging with Alternators

Lithium and LiFePO4 batteries designed for automotive use can be charged directly by an alternator. However, for deep cycle batteries, a DC-DC charger is recommended to prevent damage and ensure proper charging.

Why Use a DC-DC Charger?

DC-DC chargers regulate the alternator’s power output to match the battery’s charging needs. They prevent overcharging and potential damage to both the battery and the alternator.

 

 

Battery Maintenance and Troubleshooting

Should You Use Float Chargers or Battery Maintainers?

No, float charging or maintaining is not recommended for lithium batteries. They should be disconnected once fully charged to prevent metal plating and reduced lifespan.

Checking Charging Status

Use the indicator lights on your charger. Typically:

  • Red Light: Charging
  • Green Light: Fully charged

Troubleshooting Charging Issues

If your battery isn’t charging:

  1. Check Voltage: Use a voltmeter to test the battery and charger.
  2. Reset BMS: If the voltage is <1V, the BMS may have triggered. Connect to a lithium-specific charger to reset.

Battery Specifications and Performance

Voltage Levels

  • Fully Charged: 14.4V
  • Discharging: Steady from 13.4V to 12.8V, then drops rapidly at end.

Battery Management System (BMS)

The BMS monitors and manages charging, discharging, and safety protections. It prevents overcharging, overheating, and short circuits.

Resetting BMS

To reset, connect to a lithium charger. This will re-activate the battery and allow it to recharge.

Calculating Run Time

To estimate run time:

Run Time (hours)=Battery Capacity (Ah)Power Draw (A)\text{Run Time (hours)} = \frac{\text{Battery Capacity (Ah)}}{\text{Power Draw (A)}}

Operating and Storage Conditions

Temperature Ranges

  • Discharging: Safe below freezing, with up to 70% power output.
  • Charging: Optimal in ambient temperatures up to 149°F.

Storage

Store batteries in a cool, dry place. They have a low self-discharge rate (<5% per month), so long-term maintainers are unnecessary.

Conclusion

Properly charging and maintaining your lithium and LiFePO4 batteries is crucial for ensuring their longevity and performance. By using the correct chargers, monitoring charging status, and following recommended practices, you can make the most out of your battery investments.
