Battery capacity: 144 Wh · Chemistry: li-ion
The Powersports Lithium ATV Battery represents a significant upgrade for riders who demand reliability in demanding terrain and variable weather conditions. Unlike traditional lead-acid batteries that suffer from cold-start struggles and gradual capacity fade, lithium-ion chemistry delivers consistent cranking power whether you're navigating frozen mountain passes or tackling summer desert trails. The lightweight construction means your ATV remains nimble and responsive, while the inherent energy density of lithium compounds ensures you won't be stranded mid-ride due to premature battery drain. This combination makes the battery particularly valuable for remote riding where recovery is difficult and consistency is non-negotiable.
Proper maintenance of your lithium battery begins the moment you receive it and extends through seasonal storage cycles. Lithium-ion cells thrive when kept at moderate charge states during off-season storage rather than left fully depleted or constantly topped up—this simple practice can significantly extend the battery's lifespan and prevent the capacity fade that riders sometimes attribute to defective equipment. Avoid exposing the battery to extreme temperature swings, store it in a cool, dry location when your ATV sits for weeks or months, and consider a smart charger designed specifically for lithium chemistry to prevent overcharging, which can stress the internal cell management system and shorten useful life in the field.
With the fastest charger listed here (Quick charger, 100W) it takes about 2 h 2 min. With the slowest (Standard charger, 30W) it takes about 6 h 47 min. Lightweight lithium battery for ATVs and powersports vehicles offering superior cranking power and extended battery life.
Frequently asked questions
- How long does it take to charge a Powersports Lithium ATV Battery (12V, 12Ah, Li-ion)?
- From 0% to 100% with the standard 50W charger, it takes about 4 h 4 min. Using a faster charger shortens that; using a weaker one extends it, see the table above for exact numbers.
- Why does my lithium ATV battery perform differently in cold weather compared to my old lead-acid setup?
- Lithium-ion batteries are more temperature-sensitive than lead-acid batteries—cold conditions temporarily reduce available power delivery as the chemical reactions inside the cells slow down. However, this is a reversible effect; once the battery warms up through use, full performance returns. The advantage is that lithium maintains its baseline capacity far better than lead-acid over repeated freeze-thaw cycles, so you won't see permanent degradation the way you would with traditional batteries. If you frequently ride in harsh winter conditions, storing the battery indoors and installing it just before use will help maximize starting performance.
- What should I do if my lithium battery sits unused for several months between riding seasons?
- Before storing your ATV for an extended period, charge the battery to a moderate level rather than leaving it fully drained or fully charged. Lithium cells maintain optimal longevity when kept at a balanced state during dormancy, which reduces internal stress and self-discharge. Store the battery in a cool, dry environment away from direct sunlight and extreme temperature fluctuations. When spring arrives and you're ready to ride again, the battery should retain its charge well; simply verify the voltage before reinstalling, and you'll be ready for another season of reliable starting power and ride-time performance.
- How is this charge time calculated?
- We divide the energy needed (144 Wh times the percentage you're charging) by the charger's effective power, which is the charger's wattage times the battery chemistry's real-world charging efficiency (85% for Lithium-ion (Li-ion / Li-Po)). The same formula powers both this page and our API.
