Their lightweight design, long cycle life, and self-heating capabilities make them ideal for cold climates and demanding automotive applications, offering superior reliability and efficiency compared to traditional lead-acid batteries.
What Are the Key Specifications of the 12V 40Ah and 36Ah LiFePO4 Car Starting Batteries with 400A CCA?
These batteries operate at a nominal voltage of 12.8V with capacities of 40Ah and 36Ah, respectively, providing energy outputs around 512Wh and 460.8Wh. They offer a robust 400A CCA rating to ensure reliable engine starts, even in cold weather. The maximum continuous charge current is typically 80A, with discharge currents up to 150A. Compact and lightweight—around 5 kg—with dimensions approximately 198 x 128 x 200 mm, they fit easily in various vehicles. Designed for over 4000 charge cycles at 80% depth of discharge, these batteries feature an IP65-rated ABS case, self-heating technology, and operate efficiently within temperature ranges from -30°C to 75°C.
How Does a 400A CCA Rating Affect Starting Performance in LiFePO4 Batteries?
Cold Cranking Amps (CCA) measure a battery’s ability to deliver a high current burst to start an engine in cold conditions. A 400A CCA rating means the battery can supply 400 amps at -18°C for 30 seconds without dropping below a critical voltage. This ensures quick, reliable starts in cold weather, reducing engine strain and improving vehicle reliability. LiFePO4 batteries maintain higher CCA performance in low temperatures compared to lead-acid batteries, making the 12V 40Ah and 36Ah models excellent choices for cold climates.
Why Is LiFePO4 Technology Superior to Lead-Acid for Automotive Starter Batteries?
LiFePO4 batteries offer multiple advantages over lead-acid batteries:
-
Longer Lifespan: Over 4000 cycles at 80% depth of discharge versus 300-500 cycles for lead-acid.
-
Lighter Weight: Approximately 60% lighter, reducing vehicle weight and improving fuel efficiency.
-
Faster Charging: Can handle higher charge currents for quicker recharge.
-
Stable and Safe Chemistry: Lower risk of thermal runaway and no toxic heavy metals.
-
Better Cold Weather Performance: Retains high CCA at sub-zero temperatures.
-
Lower Self-Discharge: Holds charge longer during storage.
These benefits translate into better reliability, lower maintenance, and total cost savings over the battery’s life.
Which Vehicles Are Best Suited for the 12V 40Ah and 36Ah LiFePO4 Starter Batteries?
These batteries are ideal for:
