They hold their charge for months, ensuring your bike fires up the first time, every time. We understand the "outdoors" isn't just about the water; it's about the trail and the open road. We’re committed to providing the technical info you need to choose the right cold-cranking amps (CCA) for your ride, backed by the personal support only a founder-led company can provide.
Questions About Motorcycle Lithium Batteries?
The biggest advantage is the Power-to-Weight ratio. A standard lead-acid motorcycle battery can weigh 10–15 lbs, while a Thor Lithium equivalent weighs as little as 2–3 lbs. Beyond the weight savings, Thor Lithium provides a much stronger, more consistent cranking voltage, which leads to faster, crisper engine starts, especially on large-displacement V-twins.
Yes. Lithium cells are much denser than lead-acid, meaning we can pack more power into a smaller footprint. Our motorcycle-compatible models often come with modular spacers or are designed to match standard OEM case sizes (like YTX series), ensuring a snug fit in your factory battery box without needing custom brackets.
No. Most traditional motorcycle Battery Tenders have a desulfation mode that can damage lithium cells. To protect your investment, you should use a Thor Lithium-optimized charger.
However, because Thor batteries have an incredibly low self-discharge rate, you likely won’t even need a tender during the off-season—just disconnect the negative terminal and it will stay charged for months.
Lithium batteries actually wake up as they are used. If your bike is sluggish on a cold morning, turning on your headlights for 30–60 seconds will actually pull a small amount of current, warming the internal cells and increasing the battery’s cranking output.
For riders in extreme cold, our Heated Series technology ensures the battery is ready to rip regardless of the temperature.
Absolutely. Many touring riders prefer Thor because our LiFePO4 chemistry handles the constant draw of accessories better than lead-acid. Because Thor Lithium maintains a steady voltage throughout the discharge cycle, your heated gear and electronics will perform at 100% until the moment you turn the bike off.
Yes. Unlike traditional lead-acid batteries that contain liquid acid which can leak if the bike is laid over or the battery is mounted at an angle, Thor Lithium is a solid-state design. There is no liquid inside, meaning you can mount it in any orientation—sideways, upside down, or at an angle—without any risk of leaks or damage.
