Lithium ATV & UTV Batteries

Lightweight, High-Performance Battery Replacement for ATVs and UTVs

Looking for the best ATV battery, a long-lasting UTV battery, or a lightweight lithium battery for your ATV or UTV?

EarthX lithium batteries use Lithium Iron Phosphate (LiFePO4 or LFP) chemistry to provide high starting power, low weight, low self-discharge, and long service life.

EarthX batteries are designed for demanding powersports applications, including ATVs, UTVs, side-by-sides, utility vehicles, and off-road vehicles.

Whether you’re replacing a worn-out lead-acid battery or upgrading your ATV or UTV for more accessories and better performance, lithium technology can provide significant advantages.

Why Choose a Lithium Battery for an ATV or UTV?

ATVs and UTVs are often used in demanding conditions. They may need to start in extreme cold, operate winches and snowplows, power lights and stereos, or sit unused for months at a time.

A properly selected EarthX lithium battery can provide:

More Capacity in the Same Space

ATVs and UTVs often have limited battery-box space.

If you’ve added accessories such as winches, snowplows, heated gear, stereos, GPS systems, or additional lighting, your electrical demands may be greater than the original battery was designed to handle.

An appropriately sized EarthX lithium battery can provide increased capacity or higher cranking performance while fitting within the available battery space.

Lightweight ATV & UTV Battery

One of the biggest advantages of lithium technology is weight reduction.

EarthX lithium batteries can weigh approximately 80% less than comparable lead-acid batteries, depending on the battery model.

For performance ATVs, racing vehicles, and UTVs, removing unnecessary battery weight can benefit acceleration, handling, and overall vehicle weight.

For example, the EarthX ETX36D weighs approximately 3.9 pounds and provides 320 CCA. A comparable Yuasa YTX20HL-BS weighs approximately 15.1 pounds and provides 310 CCA.

That is approximately 11.2 pounds of weight savings from the battery alone.

More Usable Battery Capacity

Lead-acid battery voltage drops as the battery is discharged, which can limit the amount of usable energy available to electrical equipment.

EarthX LiFePO4 batteries maintain a higher voltage throughout their discharge cycle, allowing a greater percentage of the battery’s capacity to be used effectively.

This can be particularly useful in an ATV or UTV with accessories that place additional demands on the electrical system.

Higher Resting Voltage

A fully charged EarthX 12V LiFePO4 battery has a typical resting voltage of approximately 13.28 volts, compared with approximately 12.4–12.8 volts for a lead-acid battery depending on its state of charge.

The higher voltage and strong cranking capability of a lithium battery can provide excellent starting performance.

Low Self-Discharge

ATVs and UTVs often sit unused for extended periods.

EarthX LiFePO4 batteries have a very low self-discharge rate of approximately 1–2% per month under normal conditions.

This means the battery can retain most of its charge during periods of storage.

However, the vehicle itself may continue to draw power while turned off. Accessories, alarms, electronics, and other parasitic loads can eventually discharge any battery.

For extended storage, follow EarthX storage recommendations and disconnect the battery when appropriate.

Integrated Battery Management System

EarthX lithium batteries incorporate an integrated Battery Management System (BMS) designed to monitor and protect the battery.

Depending on the model, the BMS can provide protection against:

  • Overcharging

  • Over-discharging

  • Excessive cranking

  • Excessive temperature

  • Short circuits

  • Cell imbalance

Some EarthX batteries also feature an LED indicator that can alert you to certain battery conditions.

The BMS helps protect the battery from conditions that could otherwise shorten its service life.

No Liquid Sulfuric Acid

Unlike conventional flooded lead-acid batteries, EarthX LiFePO4 batteries do not contain liquid sulfuric acid.

There is no liquid acid to spill or leak onto your ATV, UTV, wiring, battery compartment, or other components.

EarthX lithium batteries also do not require adding water and do not sulfate like lead-acid batteries.

Long-Lasting ATV & UTV Batteries

If you’re searching for a long-lasting ATV battery or UTV battery that lasts a long time, battery chemistry is an important consideration.

LiFePO4 batteries can provide substantially more charge/discharge cycles than conventional lead-acid batteries.

A properly maintained EarthX battery can provide a significantly longer service life than many lead-acid batteries. Actual battery life depends on the model, charging system, temperature, storage conditions, depth of discharge, and use.
