Upgrade your mowing experience with the TYKOOL U1-M-480 Lithium LiFePO4 Battery, the high-performance 12V 12Ah power source designed for the modern North American lawn. With a staggering 480 CCA, this battery provides the reliable "first-time" start that John Deere, Craftsman, and Cub Cadet owners demand. IMPORTANT SAFETY NOTICE: Many older-generation riding mowers lack a stabilized charging system. To protect your investment, this lithium battery requires a regulated output of less than 15.0V. For machines without a rectifier, we recommend disconnecting the charging lead and using a dedicated external lithium charger. TYKOOL replaces traditional BCI Group U1, U1-7, and U1-9 lead-acid batteries with a unit that is 70% lighter and lasts up to 10 times longer. The integrated LCD display keeps you informed of your battery's charge level, while the IP66 waterproof design ensures it survives the toughest garden conditions. Say goodbye to acid leaks and terminal corrosion forever.
