The Estry lithium replacement cell delivers 5200mAh at 3.7V for Micro CA25, CA-300 and CA-100 inspection cameras.

The pack weighs 175.0g and is rated at 19.24Wh.

Ideal for Camera Operators Needing a Direct Swap

Technicians who rely on the listed Micro inspection models will find a plug-compatible power source with certified safety marks. Users of other camera brands or devices requiring a different voltage, capacity or physical size should select a battery matched to their specific equipment.

Steady Output During Extended Inspections

The lithium chemistry maintains a stable 3.7V through long recording sessions rather than sagging after a brief burst. Protection circuits prevent deep discharge when the camera runs unattended, preserving cycle life across repeated daily use.

Questions about this item

Which Micro inspection camera models does the Estry 5200mAh 3.7V lithium battery replace?

The Estry battery replaces the original power pack in the Micro CA25, CA-300, Micro CA-300 Inspection Camera, CA-100, and units marked 37888 or 40798.

Will the Estry battery fit if I keep my original Micro CA-300 chassis and battery door?

Yes, the replacement pack measures 71.4 x 39.45 x 21.0 mm and weighs 175.0 g, matching the factory dimensions so the original battery door closes normally.

How can I verify the Estry battery is delivering the rated 5200mAh capacity after installation?

Run the inspection camera until it shuts down, then recharge fully; a healthy pack should power the device for a runtime consistent with the 19.24 Wh rating.
