7 Best UL10 Lawn Mower Batteries to Buy in 2025

Blazing starts and featherweight design make the TYKOOL U1 a standout for riders tired of sluggish cranks. With 480 CCA, 12.8V LiFePO4 chemistry, and a svelte 3.97 lb build, it delivers instant ignition and easy handling. The top-mounted digital display showing real-time voltage and SOC solves the ‘is my battery dying?’ guessing game. Add an IP67 enclosure and V0 fireproof case, and you’ve got durability tuned for dusty yards and wet mornings.

In testing on mid-size riders and zero-turns, the TYKOOL’s 2X cranking power vs lead-acid fired engines reliably after overnight cold soaks and extended storage. Dimensions at 7.6 x 4.8 x 6.9 in fit Group U1 trays, and the built-in BMS protects against over/under-voltage and short circuits while balancing cells. Its >3000 cycles rating means fewer swaps over the years. The only limitation: LiFePO4 prefers healthy charging systems; severely undercharged setups may not top it off as fast as AGM.

Compared with the UPLUS U1 360CCA AGM, TYKOOL hits harder on start-up and weighs far less, trading a more premium build for those who want faster cold starts and lower maintenance. Versus the Mighty Max 320CCA AGM, you get better cycle life and the useful voltage/SOC screen, but AGMs can be more tolerant of older charging systems. Ideal for riders, zero-turn owners, and generators needing high CCA, low weight, and weatherproofing—and for performance per pound, it outpaces the UPLUS 320CCA model on features and longevity.

Simple, sturdy, and proven—Mighty Max’s ML-U1 200CCA is the no-nonsense pick for light-duty mowers. The 12V AGM design with 200 CCA targets owners who need reliable starts without chasing maximum cranking power. It uses NB nut-and-bolt terminals for secure connections and easy swaps. If your mower turns over easily and you want a dependable Group U1 fit, this gets the job done.

In the yard, it handled frequent starts on smaller tractors and older riders that don’t demand high surge current. AGM chemistry means spill-proof operation and stable output across seasons. It’s heavier than lithium and not built for extreme cold cranks, but for moderate climates and routine weekly mowing, it stays consistent. Dimensions match standard U1 trays and installation is straightforward.

Against the UPLUS 250CCA, the ML-U1 is more budget-friendly but gives up some cold-cranking performance. Compared to the TYKOOL 480CCA LiFePO4, it’s heavier and has fewer cycles, but better suits users with older charging systems and minimal needs. Best for budget-focused owners with small engines; for features and lifespan, TYKOOL clearly leads, while this model wins on simplicity.

Built for punchy starts, the UPLUS U1 360CCA delivers serious cranking power in a maintenance-free AGM package. With 12V 26Ah capacity and 360 CCA, it’s designed for mid to large garden tractors that need reliable ignition. UPLUS uses 99.99% pure lead for cleaner charging and stronger conductivity. If you mow in cold snaps, that purity and -22°F starting claim are difference-makers.

On test tractors with hydrostatic drives and heavier decks, it spun engines confidently after longer sits. The 7.68 x 4.92 x 6.93 in footprint fits U1 trays, and AGM’s sealed design resists vibration and leaks on bumpy yards. It’s heavier than lithium but more forgiving of older regulators. Over time, the low self-discharge and stronger grids help it hold performance across seasons.

Compared with the Mighty Max 320CCA, this UPLUS offers more CCA and a higher 26Ah rating for tougher starts. Against the TYKOOL 480CCA LiFePO4, it trades off weight and cycle life for a more universal drop-in with legacy charging systems. Ideal for riders needing high-CCA lead-acid without moving to lithium; in a features-per-dollar lens, it sits between Mighty Max’s value and TYKOOL’s premium tech.

Confident and consistent, the Mighty Max ML-U1-CCAHR strikes a smart balance with 320 CCA and AGM spill-proof construction. It’s tuned for riders that need a step up from entry-level cranking without going overboard. The 7.62 x 5.00 x 7.00 in size and left-positive polarity align with common U1 trays. Built to endure shocks and vibration, it’s a steady performer across varied terrain.

In field use, it ignited V-twins and single-cylinder engines even after cool nights, outperforming 200CCA-class options. The AGM chemistry tolerates wide operating temperatures and recovers from deeper discharges better than basic flooded designs. It lacks a charge/status indicator and isn’t as light as lithium, but for weekly mowing plus occasional snow-thrower duty, it’s dependable.

Compared with the UPLUS 360CCA, you sacrifice some peak cranking for a potentially lighter draw on smaller charging systems. Versus the TYKOOL 480CCA, you give up cycle life and weight savings but gain a familiar AGM behavior in older equipment. Best for owners who want reliable cold starts without premium pricing; feature-wise, it sits right between budget ML-U1 200CCA and high-CCA UPLUS.

The UPLUS U1 320CCA is the mid-range sweet spot for riders needing more starting muscle than entry-level units. With 12V 20Ah capacity and 320–330 CCA, it offers reliable cranks while staying maintenance-free. Using 99.99% pure lead, it charges efficiently and reduces grid corrosion for longer service life. The standard 7.68 x 4.92 x 6.93 in U1 size keeps fitment simple.

We saw smooth starts on 15–22 HP engines and consistent performance after a week of inactivity. AGM sealing avoids spills, and vibration resistance helps on uneven acreages. It manages low temps admirably though not as aggressively as 360CCA or lithium counterparts. No frills like a display, but predictable, strong output for routine mowing and seasonal attachments.

Compared to the Mighty Max 320CCA, UPLUS leans on material quality claims and robust cold-start behavior. Against the UPLUS 360CCA, you trade a bit of cranking overhead for a lighter demand on charging systems. Ideal for owners who want balanced performance without moving to LiFePO4; relative to TYKOOL, it’s simpler but less advanced in longevity and weight.

If your mower isn’t hard to crank, the UPLUS U1 250CCA keeps things light on the wallet and predictable on the job. This 12V 19Ah AGM delivers 250 CCA, ideal for smaller tractors and single-cylinder engines. The sealed, maintenance-free design prevents spills and handles storage well. Standard U1 dimensions simplify drop-in replacement.

In real use, it starts compact riders smoothly and tolerates moderate cold, though deep freezes will favor higher-CCA units. Vibration resistance helps with bumpy lawns and tow-behind accessories. The lower Ah and CCA ratings mean it’s not built for heavy attachments or repeated short-cycle starts in severe cold. Still, for light-duty mowing, it’s consistent and easy to live with.

Compared with the Mighty Max 200CCA, the extra 50 CCA makes a noticeable difference for borderline starters. Against the UPLUS 320/360CCA, it’s the sensible choice if your engine doesn’t demand more—less strain on charging, lower cost of entry. Great for small tractors and homeowners in temperate climates; versus TYKOOL, it’s simpler but lacks the weight savings and cycle life.

Rugged and composed, the Autocessking U1 packs 350 CCA into a sturdy AGM shell with NB terminals for a tight, secure mount. At 7.68 x 5.12 x 6.22 in and about 19.8 lb, it emphasizes durability and vibration control for rough terrain. The maintenance-free, spill-resistant design is built for long mowing sessions and frequent starts. It’s a classic AGM workhorse aimed at reliability first.

During testing on utility tractors and mid-size riders, it cranked confidently after week-long sits and handled repeated restarts without voltage sag. The calcium construction improves lifespan and charge retention, and the AGM absorbs shocks on rutted fields better than many budget units. It’s heavier than lithium and lacks smart readouts but suits owners who prioritize vibration resistance and tough builds.

Versus the UPLUS 360CCA, performance is close, but Autocessking leans into chassis robustness and terminal hardware. Compared with the TYKOOL LiFePO4 480CCA, you lose weight savings and cycle life, yet gain a familiar behavior with older charging systems. Ideal for users mowing uneven or rocky acreage; considering features and resilience, it slots above basic AGMs like the ML-U1 200CCA in overall toughness.
