Estry M550S 2.4V 2000mAh standard battery

Direct Replacement Battery

The Estry M550S is a nickel-metal hydride pack rated at 2.4 volts and 2000 milliampere-hours. It matches the original AS037 part number and fits IMET M550S Wave L, Wave S, I060-AS037 and BE5000 models. The cell delivers 4.8 watt-hours and weighs 92.0 grams in a 53.3 by 39.3 by 20.8 millimetre case. Built-in safeguards protect against overcharge, over-discharge, over-voltage and short circuits.

Suitable for Exact Model Owners

This pack suits owners who need a like-for-like swap for a depleted AS037 cell in the listed IMET devices. Buyers whose equipment uses a different voltage, capacity or physical footprint should look elsewhere, as the connector and dimensions are specific to the M550S series. The one-year battery-pack coverage applies only when the correct model match is confirmed before purchase.

Steady Output Under Load

Nickel-metal hydride chemistry provides a stable voltage plateau through most of the discharge cycle, so connected hardware sees consistent power until capacity nears empty. The protection circuitry interrupts current if a fault develops during extended use, preventing cell damage. With 2000 milliampere-hours available, runtime scales directly with the host device’s average current draw.
