Drop-in Ni-MH replacement

The Estry RQ-SX43 is a 1.2V 1200mAh nickel-metal-hydride cell built to match the original battery specifications for a wide range of portable devices. It suits users who need a direct, new-condition swap without soldering or adapter cables. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certification for regulated safety and environmental compliance.

Low self-discharge chemistry

Ni-MH construction delivers stable voltage through the discharge cycle and generates negligible heat during normal charge and discharge rates. No active cooling is required and the cell operates silently, making it suitable for enclosed battery compartments in compact electronics. Built-in protection guards against overcharge, over-discharge, over-voltage and short-circuit events.

Fits listed models without modification

The cell measures 66.78 x 16.7 x 5.96mm and weighs 50.0g, matching the footprint of part numbers including RP-BP61, RP-BP62, RP-BP105, RP-BP80H and RP-BP140H. It replaces OEM packs such as HHF-1PSC, HHF-AZ201S, HHF-AZ09, HHF-AZ01 and HHF-AZ01T directly. Buyers whose device uses a different voltage, capacity or physical layout should verify compatibility before ordering.

Questions about this item

How do I install the Estry RQ-SX43 battery and which polarity step is often missed?

Slide the pack into the device compartment matching the 1.2V label to the positive terminal; the step users skip is verifying the 16.7mm width and 5.96mm thickness align before closing the latch.

What maintenance or replacement will this 1200mAh Ni-MH pack need over time?

Expect to recharge after each full discharge; the 1.44Wh cell typically lasts one year of daily cycles before capacity drops enough to warrant a fresh RQ-SX43 replacement.

What limit appears first during sustained high-drain use of this 1.2V battery?

The 1200mAh capacity depletes quickly under continuous load, so runtime ends before the over-discharge protection engages, requiring a recharge to restore output.
