Clifford 7752X Remote Start Compatible Battery 3.7V 120mAh

Clifford 7752X / 7752V / 7351V — 3.7V Li-Polymer Replacement Battery

This 3.7V 120mAh lithium-polymer cell replaces the factory battery inside Clifford remote start and keyless entry transmitters — specifically the 7752X, 7752V, and 7351V remotes. At 24.70 x 20.30 x 3.70mm, it slots into the original battery bay without modification. Voltage and footprint match the OEM spec exactly.

• 7752X, 7752V, and 7351V platform: These three remotes share the same 3.7V power rail, battery bay dimensions, and connector orientation. One cell covers all three without any adapter or wiring change.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on the bench. The BMS held voltage within the expected 3.7V nominal range and showed no erratic cutoff behaviour during the test.
• Re-sync after battery swap: Clifford remote start systems lose their pairing handshake when the transmitter loses power. After fitting the new cell, run the programming sequence for your specific Clifford control module before expecting the remote start or entry functions to respond.

Remote start not activating after battery swap

Clifford's remote start control modules use a rolling-code or fixed-code handshake that the transmitter stores in memory. When the battery is removed, that memory loses power and the stored code drops. The module receives a signal from the remote but rejects it because the code no longer matches. Putting the system into programming mode — typically by cycling the ignition or using the valet button sequence — and re-presenting the remote re-establishes the link.

Range noticeably short immediately after fitting a new cell

Li-polymer cells ship at storage voltage — typically around 3.6V — not at a full 3.7V charge. At storage voltage, transmit power is slightly lower, which cuts usable range until the cell reaches full charge. Plug the remote into its charger or charge via the vehicle's native charging method before testing range. After one full charge cycle, the cell settles at its rated voltage and range returns to normal.
