Replacement Ni-MH Pack

The Estry MH120AAAL4GC is a 4.8V 150mAh nickel-metal-hydride battery built to match the original dimensions of 31.3 x 21.56 x 11.04mm and a weight of 40.4g. It delivers 0.72Wh and includes overcharge, over-discharge, over-voltage and short-circuit protection. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Upgrading From Worn Cells

This pack replaces a depleted MH120AAAL4GC unit when run-time has fallen or the original no longer holds a charge. The jump is worth it when the device shows reduced operating time, unexpected shutdowns or a swollen case. It restores the factory voltage and capacity without requiring hardware changes.

Build Integration

The battery fits the existing compartment and connector, so no adapter or wiring modification is needed. Its certified protection circuit frees the host device from managing charge limits externally. Confirm the model number MH120AAAL4GC on the old pack before ordering to ensure physical and electrical compatibility.

Questions about this item

Will the 31.3 x 21.56 x 11.04 mm pack fit the MH120AAAL4GC compartment?

Yes, the replacement matches the original dimensions of 31.3 x 21.56 x 11.04 mm and weighs 40.4 g, so it seats directly in the same battery bay without modification.

How do I install the 4.8 V 150 mAh Ni-MH pack, and what step is often missed?

Remove the old pack, align the connector polarity exactly as the original MH120AAAL4GC, press the plug in fully until it clicks, then charge for a full cycle before first use; skipping the initial full charge is the common error.

When will the 0.72 Wh Ni-MH battery need replacing, and what certifications cover its lifespan?

Expect roughly one year of service per the maker's rating; the cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, so replace when runtime drops below useful levels.
