- [Reliable 400A Starting Power] Upgrade your equipment with 400A Cold Cranking Amps (CCA). Specifically engineered for residential riding mowers, this U1 lithium battery ensures a consistent, rapid engine ignition that outperforms standard lead-acid units, even after long idle periods.
- [10-Year Service Life & 3000+ Cycles] Stop the cycle of annual battery replacements. Powered by automotive-grade LiFePO4 cells, the TYKOOL S-400 provides over 3,000 deep cycles. It is a cost-effective, long-term power solution that lasts up to 10X longer than traditional AGM batteries.
- [Smart LCD Display & BMS Safety] Monitor your power levels in real-time with the built-in digital LCD screen showing Voltage and State of Charge (SOC). The internal Smart BMS provides 5-layer protection against overcharge, short circuits, and thermal risks.
- [V0 Fireproof & IP66 All-Weather Build] Designed for the rugged reality of American backyards. Features a V0-rated flame-retardant enclosure and IP66-rated waterproof housing. Reliable performance in humid mornings, light rain, and dusty gardening environments.
- [Advanced Winter Storage Performance] Ideal for seasonal use. Our lithium technology features an ultra-low self-discharge rate, maintaining its charge throughout the off-season. No trickle charger is required—simply disconnect for winter and it's ready for the spring mow.
- [Eco-Friendly & Maintenance-Free] Eliminate acid leaks and corrosion. TYKOOL’s non-toxic LiFePO4 chemistry is 100% lead-free and cobalt-free. Replaces multiple lead-acid battery cycles, reducing long-term ownership costs and environmental waste.
- [Mandatory Compatibility & Fitment Check] Size: 7.6x4.8x6.9 in | Polarity: [+ -]. Verified fit for 725-1707D & U1-9. But NOT for 725-17335. MUST Requires a regulated charging system (13.8V-14.6V). Attention: Please verify your mower’s voltage output before purchase.
