The TET LiFePO4 Group 49 is a lithium iron phosphate battery that delivers 80 amp-hours of capacity and an extraordinary 1800 cold cranking amps in a package that weighs roughly half of what a comparable AGM battery would weigh. The 12.8-volt nominal voltage and Group 49 form factor (13.95 by 6.93 by 7.5 inches) require careful verification against the Fusion’s battery tray dimensions, as this is a larger footprint than the standard Group 47. The built-in Battery Management System protects against overcharge, overdischarge, and short circuits.

Lithium iron phosphate chemistry offers a service life of over 1500 cycles at 100 percent depth of discharge, which represents a significant durability advantage over the 500-cycle typical lifespan of AGM batteries. The weight savings of roughly 20 pounds compared to a lead-acid battery can make a noticeable difference in overall vehicle weight distribution. The TET battery also features near-zero self-discharge, meaning it can sit unused for months and still start the engine instantly.

The key trade-offs are the upfront investment and the group size compatibility question. The Group 49 case is physically different from the Group 47 that most Fusions use, so modifications to the battery tray or hold-down may be necessary. The lithium chemistry also requires the vehicle’s charging system to be compatible — most modern alternators work fine, but older or poorly regulated systems can trigger the BMS protection. For enthusiasts willing to work through fitment and charging compatibility, the performance benefits are substantial.
