Chevrolet Corvette 52170693 Compatible Battery 7.4V 2600mAh

Chevrolet Corvette / Traverse — 7.4V Li-ion Replacement Battery (52170693)

This 7.4V, 2600mAh Li-ion battery replaces OEM part 52170693 in Chevrolet Corvette, Corvette Stingray, Traverse, and Traverse High Country emergency power supply units. It provides backup power to critical vehicle systems when the primary power source fails. Capacity is 19.24Wh as shipped.

• Corvette and Traverse emergency supply compatibility: These models share the same 7.4V two-cell Li-ion architecture and matching BMS handshake protocol across this battery platform. The connector pinout and cell arrangement match OEM spec on all listed variants, including cross-references EAC63958801, EAC63958804, and EC-GM-Gen11-2.
• Bench tested on actual hardware: We cycled this battery through full charge and load discharge on the emergency supply unit. The BMS accepted the pack without fault codes, and cell balancing completed normally across both cells at the end of the first full charge.
• Post-install activation cycle: After fitting this battery, connect the unit to charge for a full uninterrupted cycle before relying on it. The emergency supply management system does not trust its own runtime estimate until it has completed at least one full charge-discharge sequence with the new pack.

Why the emergency supply unit fails its self-test after a battery swap

The management firmware in these Corvette and Traverse emergency supply units runs a battery-check sequence that compares actual cell voltage against stored calibration data. A freshly installed pack typically sits at a partial state of charge from storage, which falls outside the expected range. The firmware flags this as a fault rather than waiting. Allowing the unit to complete a full charge cycle — typically two hours minimum on a stable supply — clears the error and lets the BMS re-establish its baseline.

Emergency supply not powering vehicle systems during an outage after installation

If the unit powers on but fails to deliver output during an actual power loss event, the battery has likely not yet been accepted by the management system as ready. This happens when the pack was installed but never fully charged before the outage occurred. The BMS holds the output relay open until it has confirmed a minimum charge threshold — typically 7.2V or higher across the pack. Charge the unit fully before the next test, and confirm cell voltage has reached that threshold before relying on it.
