Replacement Battery for SimpliSafe SSDB3 Video

This 500mAh lithium polymer cell replaces the original SimpliSafe PL502535 pack in SSDB3 and U9K-DB3000 doorbell models. It delivers 3.7 volts and 1.85Wh capacity for indoor or outdoor security devices. The pack measures 35.00 by 24.00 by 6.00 millimetres and includes overcharge, over-discharge and short-circuit protection.

Verify Model and Part Number Before Ordering

Check that your doorbell is a SimpliSafe SSDB3, U9K-DB3000 or Video Doorbell Pro and that the original battery carries part number PL502535. Confirm the connector matches the existing lead before fitting the new cell. A mismatched model or connector will prevent proper operation.

Thermal and Power Behaviour in Daily Use

The lithium polymer chemistry operates at 3.7 volts with 500mAh capacity, drawing minimal current during standby and video events. Normal use produces negligible heat and no audible noise from the battery itself. Full performance is reached after two or three complete charge and discharge cycles.

Questions about this item

Does the package include the battery only or are tools and adhesive supplied as well?

The box contains one lithium-polymer cell measuring 35.00 x 24.00 x 6.00 mm with a pre-attached connector; no tools, adhesive strips or mounting hardware are included.

Should I choose this 500 mAh 3.7 V pack or a higher-capacity alternative for my SimpliSafe Video Doorbell Pro?

This replacement matches the original PL502535 specification of 500 mAh and 1.85 Wh; a higher-capacity cell would not fit the 35 x 24 x 6 mm compartment.

What does the 500 mAh rating mean for daily operation once the battery is installed in the doorbell?

The 500 mAh / 1.85 Wh capacity restores the factory runtime, typically powering the Video Doorbell Pro through several weeks of normal motion events before requiring a recharge.
