Replacement Lithium Battery

This Estry R2R2000 battery is a direct replacement for the original AEC103550 pack. It supplies 3.7V and 1800mAh capacity in a single lithium cell measuring 49.2 x 33.5 x 10.2mm. The unit weighs 57.0g and carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications for safety and quality assurance.

Users Needing Exact Fit

Suitable for owners of devices that require the R2R2000 or AEC103550 part number. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. Buyers who need a different voltage, capacity or physical footprint should verify their device specifications before ordering.

Capacity Decides Compatibility

The 1800mAh rating determines whether this cell matches the runtime and current demands of the original equipment. Confirm that your device specifies 3.7V and 1800mAh; a mismatch in either value means this battery will not function correctly.

Questions about this item

Does the Estry R2R2000 pack include only the 3.7V 1800mAh lithium cell or are tools and adhesive supplied?

The package contains a single 3.7V 1800mAh lithium battery measuring 49.2 x 33.5 x 10.2mm and weighing 57.0g. Installation tools and adhesive are not included.

Which capacity figure should I trust — the 1800mAh in the model name or the 1700mAh shown in the detailed specs?

The manufacturer lists the capacity as 1700mAh with a 6.29Wh rating; the 1800mAh value appears in the product title but the tested specification is 1700mAh.

Will the 6.29Wh rating deliver the same runtime as the original AEC103550 cell in my R2R2000 device?

Yes, the replacement matches the original AEC103550 at 3.7V and 1700mAh (6.29Wh) and includes overcharge, over-discharge, over-voltage and short-circuit protection.
