Technika SH-Z735 Compatible Battery 3.7V 850mAh Li-ion

Technika SH-Z735 — 3.7V Li-ion Replacement Battery (WGL-0101)

This 3.7V 850mAh (3.15Wh) Li-ion cell replaces the WGL-0101 battery in the Technika SH-Z735 compact digital camera. It matches the original cell's voltage, capacity, and physical footprint — 40.20 x 35.30 x 6.10mm — so it seats correctly in the battery compartment without modification. Voltage and polarity align with the SH-Z735's power rails.

• SH-Z735 fit: The SH-Z735 uses a single-cell Li-ion pack at 3.7V nominal. This replacement shares the same connector orientation and cell dimensions as the OEM WGL-0101, so the BMS in the camera body reads it on the same voltage thresholds it already expects.
• Bench tested on actual hardware: We cycled this cell through charge and discharge under a load profile that replicates shutter actuation, LCD draw, and flash capacitor recharge. The BMS accepted the cell and stepped down correctly at low-voltage cutoff without tripping a hard fault.
• First charge cycle on the SH-Z735: Run the first full charge inside the camera body using the OEM charger or USB charge port if fitted — some compact camera BMS systems only begin accurate battery-remaining calibration after one complete in-body charge cycle from near-empty to full.

Why the SH-Z735 shows a dead battery indicator on a partially charged replacement cell

The SH-Z735 maps its battery-remaining display against the discharge curve of the original OEM cell. A new replacement cell may have a slightly different mid-range voltage profile, causing the indicator to read lower than the actual state of charge. This resolves after one or two full discharge and charge cycles, once the camera's threshold mapping aligns to the new cell's curve. If the indicator still reads erratically after two cycles, charge the cell to full inside the camera body — target a resting voltage of 4.2V before starting a shoot.

Flash not fully recycling between shots on the SH-Z735

The SH-Z735's flash capacitor pulls a short high-current burst from the battery each time it recharges between shots. As a cell ages or sits deep-discharged, internal resistance rises and the capacitor takes longer to reach full charge voltage. On a replacement cell that arrived partially discharged, this can show up immediately as a slow recycle or a flash that fires at reduced output. Charge the replacement cell to full — 4.2V resting — before your first shoot, and the recycle time should return to normal.
