The Enexer DL-12100 12V 100Ah deep cycle lithium iron phosphate (LiFePO4) battery is engineered for unwavering durability, safety, and peak performance. 

This 12V deep-cycle battery revolutionizes energy storage and power delivery. It utilizes premium quality Grade A UL1642 certified lithium iron phosphate cells and a smart battery management system, all packed into a space-efficient IP67 casing.

It outperforms traditional lead-acid batteries in every way. You get a lifespan of over 10 years, charging that's up to five times faster, and a battery that weighs 60% less. That makes it a great choice for marine use, RVs, solar PV systems, electric vehicles, trolling motors, and reliable backup power.

This battery requires zero maintenance and is built to thrive in extreme conditions, ensuring reliable energy storage and power with zero upkeep. Enexer is committed to providing only the highest quality products that last and offers a 10-year warranty on this battery.

Frequently Asked Questions

How long will a 12V 100Ah LiFePO4 battery last?

The battery is rated for 4000 cycles at 80% Depth of Discharge (DoD), providing 10+ years of reliable power depending on usage patterns and proper maintenance.

Can I use the 12V 100Ah Group 31 lithium battery as a starter battery?

No, this is a deep-cycle battery and cannot be used for starting engines.

Can I connect multiple 12V 100Ah batteries together?

Yes, it supports a maximum of 4 in series or 4 parallel configurations, but only uses identical Enexer model batteries.

What is the difference between AGM and Gel 12V 100Ah batteries?

Both are 12V 100Ah sealed lead-acid batteries. The primary difference lies in how they fix the electrolyte. AGM batteries use a fiberglass mat to soak up the acid, while Gel batteries use a silica-based paste to create a jelly-like substance.
