Replacement battery for 1ICP/18/650 packs

This Estry lithium cell is built to match the original 1ICP/18/650 1S1P specification. It delivers a nominal 3.7 V output and a rated capacity of 3000 mAh. The pack measures 66.5 x 21.65 x 18.6 mm and weighs 76.8 g. Integrated protection guards against overcharge, over-discharge, over-voltage and short circuits.

Suits devices using the 1ICP/18/650 part number

Buyers should verify their device lists this exact part number before ordering. The cell is not intended for applications requiring a different voltage, capacity or form factor. Users needing higher energy density or a multi-cell configuration will not be served by this single 1S1P unit.

Certified to ISO9001, RoHS, CE, UN38.3 and MSDS

The bundle includes the battery cell only; no charger, cables or mounting hardware are supplied. Compliance paperwork supports safe transport and regulatory acceptance. The certifications confirm manufacturing quality and material restrictions but do not alter the electrical characteristics of the cell.

Questions about this item

What device connector does the 1ICP/18/650 1S1P pack require to fit correctly?

The pack uses the original 1ICP/18/650 1S1P part number; match that number to your device’s battery compartment to ensure the connector and pin layout are identical.

Will the 66.5 x 21.65 x 18.6 mm dimensions and 76.8 g weight let it sit in the same bay as the old cell?

Yes — those are the exact measurements of the original pack, so it occupies the same space and adds the same mass as the cell you are replacing.

How can I verify the 3.7 V 3000 mAh cell is delivering its rated 12.4 Wh after installation?

Charge fully, then run a discharge test at the rated current; a healthy pack will yield about 12.4 Wh before the protection circuit cuts off.
