Direct Visonic MCS-740 and SR-740 PG2 replacement

This Cameron & Co DS-CS-VPX740BT battery is built for Visonic alarm system models MCS-740 and SR-740 PG2. It matches original part numbers 103-304742-2 and 2XER18505M. Installers and system owners use it to restore primary or backup power in compatible panels. The black Li-SOCl2 cell is non-rechargeable and ships new.

Replaces depleted original cells in installed panels

The unit replaces the factory-fitted battery when its voltage drops below the level needed for reliable supervision. A swap is worth it when the panel reports a low-battery fault or after the service interval recommended by the installer. It is not for systems that require a rechargeable chemistry or a different form factor.

3.6 V 4000 mAh capacity delivers 14.40 Wh

The lithium thionyl chloride chemistry provides 3.6 V and 4000 mAh for long standby duration in alarm applications. It comfortably handles the periodic supervision transmissions and siren activation currents specified for the MCS-740 and SR-740 PG2. The cell runs out when the panel indicates end-of-life or after the rated capacity is exhausted.

Questions about this item

What are the exact dimensions of this DS-CS-VPX740BT battery so I can confirm it fits the Visonic MCS-740 housing?

The battery measures 50.90 x 37.10 x 19.00 mm, matching the original Visonic MCS-740 and SR-740 PG2 compartment specifications.

How do I correctly install the battery and which polarity step is commonly missed?

Insert the single black Li-SOCl2 pack observing the marked + and – terminals; the step often missed is verifying both 3.6 V cells read 3.6 V each before closing the cover.

When will this non-rechargeable 4000 mAh Li-SOCl2 pack need replacement in a Visonic alarm sensor?

Expect several years of service; replace when the panel reports low battery or voltage drops below 3.6 V per cell, as the 14.40 Wh capacity cannot be recharged.
