Hikvision H13 Thermal Camera Compatible Battery 3.7V 5000mAh

Hikvision H13 / H16 Series — 3.7V Li-ion Replacement Battery (E097-13-1S1P26650)

This is a 3.7V, 5000mAh (18.5Wh) Li-ion replacement battery for the Hikvision H13, H13 Pro, H16, and H16 Pro handheld thermal imaging cameras. It matches the OEM part number E097-13-1S1P26650 and slots into the same battery compartment. If your original cell is no longer holding charge during field inspections, this is a direct swap.

• H13 and H16 platform compatibility: The H13 and H16 series share the same battery bay, connector pinout, and BMS handshake protocol. Both models draw current from a single 26650-format cell, so one battery covers the full range — including Pro variants — without any hardware modification.
• Bench tested on actual hardware: We ran this cell under combined load — detector heating element active, display at full brightness — and monitored the BMS across full discharge. Protection tripped at the correct low-voltage threshold with no premature cutoff or false full-charge readings.
• Thermal detector warm-up after swap: After fitting a fresh battery, power the camera on and wait 60 seconds before taking any measurements. The uncooled detector needs the internal electronics to stabilise thermally before it can establish an accurate baseline. Readings taken in the first 30 seconds will drift.

Thermal accuracy affected at low state of charge

The H13's microbolometer detector and its associated signal processing circuit are sensitive to supply voltage. As the cell discharges below roughly 3.5V, the detector bias voltage drops slightly, which shifts temperature readings by as much as 2–3°C before the low-battery indicator appears on screen. This is not a camera fault — it is a voltage-supply issue. If measurements start drifting or losing sharpness in cold conditions, check cell voltage rather than recalibrating the camera. Swap the battery when resting voltage drops below 3.5V under load.

Camera shuts down mid-inspection despite showing partial charge

The H13 runs two constant loads simultaneously — the detector heating element and the display backlight — which together pull more current than casual use estimates. An ageing or degraded cell can show 40–50% charge on the indicator but trip the BMS protection circuit the moment both loads spike simultaneously during image refresh. The result is an abrupt shutdown with no low-battery warning. A fresh cell resolves this: at 5000mAh and a stable internal resistance, the BMS has enough voltage headroom to handle the combined draw without hitting the protection threshold prematurely.
