The Direct Drop-In Upgrade for Group 24 Applications
Replace your old lead-acid battery without a single modification. Our Group 24 LiFePO4 battery is precision-engineered to fit the exact footprint and terminal configuration of the industry-standard Group 24 size. Experience a seamless transition to lithium power—more energy, zero maintenance, and a fraction of the weight, all in a perfectly familiar package.
Why Our Prismatic Group 24 Battery is a Better Value:
Perfect Fit, Zero Hassle:
Designed to the exact Group 24 (DIN 66) dimensions, ensuring it drops directly into the existing battery tray of your vehicle or equipment without any modifications.
Massive Weight Reduction:
Weighing up to 70% less than the lead-acid battery it replaces, it lightens your load for improved efficiency and easier, safer handling.
True Deep Cycle Capability:
Utilize nearly 100% of the rated capacity without damaging the battery, providing significantly more usable energy than a similarly sized lead-acid battery.
Maintenance-Free Reliability:
A sealed, rugged design means no more watering, no corrosive acid leaks, and no need for equalization charges. Install it and forget it.
