Replacement Ni-MH battery pack

This Estry SP-N2 replacement pack uses nickel-metal hydride chemistry rated at 2.4 volts and 650 milliampere-hours for 1.56 watt-hours. It matches the original dimensions of 45.0 by 20.7 by 10.6 millimetres and weighs 50.0 grams. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuits. The cell carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications.

Suitable devices and limitations

The pack fits equipment that specifies the SP-N2 model or an equivalent 2.4 volt Ni-MH pack of the same physical size. Devices requiring a different voltage, chemistry, capacity or connector layout will not work with this unit. Buyers needing longer runtime or a higher voltage platform should look for an alternative power source.

Deciding specification

The 2.4 volt, 650 milliampere-hour Ni-MH rating is the single figure that determines compatibility. Confirm the original battery shows exactly these values before ordering.

Questions about this item

How long can the 650mAh capacity sustain a typical cordless phone before the voltage drops below 2.4V?

The 650mAh rating delivers 1.56Wh at 2.4V; actual talk time depends on the handset current draw and will shorten as the pack ages.

Does the Ni-MH pack stay cool and quiet during continuous charging or heavy daily use?

Ni-MH chemistry runs silently and generates only mild warmth; the built-in protection circuit prevents over-voltage and short-circuit heating.

What must I already own for this SP-N2 pack to work in my device?

You need a handset or base station designed for the SP-N2 form factor (45.0 x 20.7 x 10.6 mm) with matching polarity contacts.
