Samsung Digimax L55 Replacement Battery 3.7V 1230mAh SB-L1237

Samsung Digimax L55 / L55W / L85 — 3.7V Li-ion Replacement Battery (SB-L1237)

This is a 3.7V, 1230mAh (4.55Wh) lithium-ion battery that replaces the Samsung SB-L1237 and SLB-1237 cells. It fits the Digimax L55, Digimax L55W, and Digimax L85 compact digital cameras. Same voltage, same form factor, same connector as the original.

• Digimax L55, L55W, and L85 compatibility: All three models share the same battery bay dimensions, 3.7V rail, and contact layout. The SB-L1237 footprint and connector pin-out are identical across the range, so one SKU covers all three bodies without modification.
• Bench tested on actual hardware: We cycled this cell through charge and discharge on a Digimax L55 body. The BMS accepted the cell without rejection flags, voltage reporting tracked correctly through the discharge curve, and the low-battery cutoff triggered at the expected threshold.
• First-use charge cycle on the Digimax L55: Run one full charge cycle through the camera body or OEM charger before your first shooting session. The Digimax BMS maps battery-remaining display against a charge curve it calibrates on first use — skipping this step can cause the indicator to read inaccurately from the start.

Battery percentage jumping erratically on the Digimax L55 display

The Digimax L55 maps its battery indicator against fixed voltage thresholds calibrated to the original cell's discharge curve. A new replacement cell may have a slightly different discharge profile, causing the indicator to jump — for example, dropping from 75% to 40% in a single shot. This is not a cell fault. Run two full charge-discharge cycles through the camera body and the BMS will re-map its thresholds to the new cell's curve. After that, the indicator stabilises and tracks accurately through the full discharge range.

Camera showing dead battery icon immediately after inserting a charged replacement

Some Digimax L55 bodies reject a new cell on first insertion if the cell voltage sits outside the narrow window the BMS expects at startup. This triggers a false dead-battery warning even on a fully charged replacement. Remove the battery, insert it again, and power on — most cases clear on the second insertion attempt. If the warning persists, place the cell in an OEM charger until the charge LED confirms a full charge, then reinsert. The camera should read the cell correctly at 4.2V full charge.
