Direct replacement for Acare Pulse AH-MX

The Estry standard battery matches the LB-03 part number and fits the Acare Pulse AH-MX device. It supplies 3.7 V nominal voltage with a rated capacity of 1700 mAh and an energy content of 6.29 Wh. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits.

Upgrade from depleted or aged original cells

When the factory pack no longer holds a useful charge this single lithium cell restores the original run time. The jump is worth it if the device still meets your clinical needs but the old battery drains too quickly or shows swelling. No higher-capacity version is offered in this listing.

Limited to devices accepting the LB-03 form factor

The cell measures 50.1 x 48.9 x 13.5 mm and weighs 99.2 g, so it only fits equipment designed for that exact footprint. It carries ISO 9001, RoHS, CE, UN 38.3 and MSDS certifications but provides no charge-management circuitry beyond the integrated protection board. Buyers needing multi-cell packs or different connector layouts cannot use this unit.

Questions about this item

Will the 50.1 x 48.9 x 13.5 mm case fit the Acare Pulse AH-MX battery compartment?

The replacement cell matches the original LB-03 dimensions of 50.1 x 48.9 x 13.5 mm, so it seats directly in the Pulse AH-MX cavity without modification.

What is the correct orientation when inserting the 3.7 V 1700 mAh pack into the Pulse AH-MX?

Align the pack’s labelled side and connector polarity exactly as the original LB-03 sat; the keyed plug prevents reverse insertion, but forcing it can bend the socket pins.

How long before the 6.29 Wh lithium cell needs replacing under daily use?

The ISO9001, RoHS, CE, UN38.3 and MSDS certified pack is rated for hundreds of charge cycles; capacity fade becomes noticeable after roughly two to three years of regular daily charging.
