What's in the box:
- (1) EarthX ETX18F
- (2) Terminal adapters
- (2) 6mm screws
- Foam for proper fitment
- Made in the USA. Why it matters:
- Superior craftsmanship; rigorously tested; high-quality parts.
- Full Battery Management System (BMS): Built-in circuitry guards against over-discharge, over-charge, short circuits, excessive cranking heat, and cell imbalance — all automatically.
- 340 Peak Cranking Amps in a 2.2 lb Package: More cranking power than comparable lead-acid batteries at a fraction of the weight, for faster and more reliable starts.
- Up to 80% Lighter Than Lead-Acid: At just 2.2 lbs, the ETX18F saves meaningful weight over standard batteries for better handling and performance on every ride.
- Up to 4,000 Charge Cycles: Rated for more than 10 times the cycle life of a lead-acid battery, with a potential service life of up to 8 years.
- 2-Year Full Coverage Warranty: Non-prorated, factory-direct; your battery is fully covered, not replaced at a discounted rate like many competing brands offer.
- Engineered and Assembled in the USA: Built with nontoxic, nonhazardous LiFePO4 chemistry: No lead, no acid, and no environmental guilt.
Product Description
Is your battery the thing you dread dealing with every spring? Maybe it's given up in the middle of a ride, or sat all winter and simply refused to come back. The EarthX ETX18F lithium powersports battery was built for riders who are done with that cycle. It's a direct-fit LiFePO4 replacement for most standard motorcycle and powersport batteries, and it's engineered to outperform and outlast what came before it.
Why Riders Make the Switch
Heat kills lead-acid batteries. So does sitting unused for months. The ETX18F handles both without complaint. It holds a charge through an entire off-season (over six months) without needing a trickle charger. And because its resting voltage sits higher than a lead-acid battery, your engine cranks faster right from the first turn of the key.
The weight difference is just as noticeable. At 2.2 lbs, this battery is dramatically lighter than the one it replaces. That's real weight removed from your bike, in a location where it matters for balance and handling.
What Makes EarthX Different From Other Lithium Batteries
Here's where it gets important. Most lithium batteries on the market skip the protection electronics and then void the warranty when the battery fails because of it. The ETX18F includes EarthX's fully integrated Battery Management System (BMS), which protects your cells from the most common causes of premature battery failure: over-discharge, over-charge, excessive cranking heat, and cell imbalance. It does all of this automatically, with no special charger or seasonal maintenance required on your end.
This BMS is the same technology EarthX originally developed for the experimental aircraft market, where reliability isn't optional. That engineering pedigree is exactly why riders in demanding climates — desert heat, mountain winters, year-round commuting — choose EarthX over the alternatives.
Long-Term Value Worth Considering
A standard lead-acid motorcycle battery typically gives out after three to four years, sometimes sooner in hot or cold climates. The ETX18F is built to go the distance and comes with a 2-year full coverage warranty (not the prorated kind that leaves you splitting the cost of a replacement). For riders who want to stop thinking about their battery, this is the battery to buy once and move on.
Fitment and What's in the Box
Every ETX18F ships with terminal adapters, 6mm screws, and foam spacers for a proper fit. It replaces a range of common OEM sizes, including the YTX9-BS, YTZ10S, and YT12A-BS, making installation straightforward in most applications. If your bike uses front-mounted terminals, the included A/B/F terminal adapter handles that too.

Frequently Asked Questions
Is the EarthX ETX18F compatible with my motorcycle or powersport vehicle?
A: The ETX18F cross-references to several common OEM battery sizes, including the YTX9-BS, YTZ10S, YT12A-BS, TX9, TX10S, STX9-BS, DTX9-BS, and ES9BS. Terminal adapters, foam spacers, and mounting screws are included to assist with fitment. If you want to confirm compatibility for your specific year, make, and model before ordering, our team is happy to help — just give us a call or use the live chat.
Do I need a special charger for the ETX18F?
A: The ETX18F's built-in BMS allows it to work with most modern "smart" lead-acid chargers. Older unregulated chargers should be avoided, and for the best long-term results EarthX recommends a lithium-compatible charger. One important note: do not attempt to jump-start this battery using a large automotive battery or heavy-duty jump pack, as the voltage spike can damage the cells.
What's the difference between the ETX18F and the ETZ14C?
A: Both batteries use Case F dimensions (5.9" x 3.4"), but they're built for different priorities. The ETX18F (230 CCA / 340 PCA, 2.2 lbs) includes the full BMS with over-discharge and excessive cranking protection, and carries a 2-year warranty. The ETZ14C (330 CCA / 690 PCA, 2.5 lbs) delivers higher cold-cranking output and is designed specifically for cold-weather starts, but its BMS does not include over-discharge or excessive cranking protection, and it comes with a 1-year warranty. For most street, touring, and all-season riders, the ETX18F is the better fit.
Will the ETX18F hold up during winter storage or a long off-season?
A: Yes. The ETX18F has a very low self-discharge rate and can hold its charge for six months or more without needing a maintainer — making it a solid choice for seasonal riders. One exception: if your bike has a continuous parasitic draw (common on some Harley-Davidson models with always-on electronics), you may still want to connect a compatible maintainer during storage to prevent deep discharge over time.

Customer Reviews
Literally so light that I almost couldn't believe it was a battery. Cranks my bike faster than the old lead battery at a third the weight and it fit perfectly with a little padding (that came in the box). Great product.
