About this replacement
Samsung SMX-C14 / SMX-C20 Series — 3.7V Li-ion Replacement Battery (IA-BH130LB)
This is a 3.7V, 1300mAh (4.81Wh) lithium-ion battery built to the IA-BH130LB specification. It fits the Samsung SMX-C14, SMX-C10, SMX-C20, and SMX-C24 compact camcorders, along with over 34 additional SMX-series models. Voltage and connector pinout match the OEM part exactly.
- SMX-C and SMX-F series compatibility: These Samsung compact camcorders share the same 3.7V single-cell architecture, battery bay dimensions, and three-pin contact layout. One cell covers the full range — no adapters, no modified connectors.
- Bench tested on actual hardware: We ran this cell through the SMX-C20 body. The BMS handshake completed on first insertion. Charge acceptance via the OEM cradle charger was normal, and the battery-remaining indicator tracked consistently through the discharge curve.
- First charge protocol on SMX-series bodies: Charge this battery through the original Samsung cradle charger or directly in the camera body before your first recording session. Some SMX bodies calibrate the fuel gauge against charge current from within the body — skipping this step can cause the indicator to display erratic percentages during early cycles.
Battery percentage jumping erratically on the SMX-C14 display
The SMX-C14 maps battery percentage to a fixed voltage-threshold table tuned to the original cell's discharge curve. A new replacement cell — even a correctly specced one — has a slightly steeper voltage slope early in its life, which causes the indicator to skip levels or read low. This is not a cell fault. After two to three full charge and discharge cycles, the indicator settles and tracks accurately. If it persists past three cycles, check that the first charge was done in-body or via the OEM cradle at 4.2V termination.
SMX camcorder shows dead battery icon immediately after inserting a charged cell
This happens when the BMS in the camera body fails to complete its authentication handshake on cold insertion — typically because the cell voltage sits just below the body's wake threshold after shipping or storage. The fix is to place the battery in the OEM cradle charger for at least 15 minutes before inserting it into the body. The cradle charges without a handshake requirement, bringing the cell to approximately 3.9V, which is above the SMX body's minimum detection threshold. After that, the body recognises and accepts the cell normally.
