Battery Lithium Group 27 100Ah

The Battery Lithium Group 27 100Ah from NOCO is a next-generation lithium-ion power solution engineered for demanding applications where traditional lead-acid batteries fall short. Designed for vehicles, RVs, marine vessels, and off-grid systems, this Group 27 lithium battery delivers dependable starting power and extended cycling capability without the weight penalty or maintenance burden of conventional batteries. Whether you're powering a truck, boat, or backup power system, this 12V lithium alternative provides cranking authority with modern efficiency.

At 100 amp-hours (Ah) capacity with 1400 cranking amps, the Battery Lithium Group 27 100Ah delivers robust starting performance in cold conditions while maintaining high usable energy reserves for auxiliary loads. Lithium-ion chemistry eliminates the sulfation and acid stratification problems endemic to lead-acid units, ensuring consistent voltage delivery across thousands of charge cycles. The interchangeable terminal design allows drop-in replacement into existing Group 27 battery boxes, simplifying installation without bracket modifications. At just 32.55 lbs—roughly one-third the weight of an equivalent lead-acid battery—this unit reduces vehicle weight, improves fuel economy, and eases handling during installation or maintenance.

This lithium battery excels in dual-battery setups, marine auxiliary power, RV house banks, and vehicles exposed to frequent deep-cycle demands. Off-grid solar and backup power systems benefit from the chemistry's superior cycle life and resistance to temperature extremes. The compact 11 × 8 × 13 in footprint and lightweight profile make it ideal for weight-sensitive applications—motorsports, overlanding, and aviation systems where every pound matters. Installation is straightforward for any owner comfortable with basic battery connections; the NOCO NLX27 is compatible with standard battery chargers and monitoring systems designed for lithium chemistry.
