Direct Replacement

The Estry P0871365 is a nickel-metal hydride battery built to match the original specifications for Nortel equipment using part number P0871365. It delivers 3.6V and 1200mAh capacity in a 50.43 x 42.54 x 14.4mm form factor weighing 90.3g. This unit suits technicians restoring cordless handsets or base stations that require this exact pack. Buyers needing a different voltage, chemistry or connector layout should look elsewhere.

Low-Heat Operation

Ni-MH chemistry runs cool during typical charge and discharge cycles, so the pack adds negligible thermal load inside the handset enclosure. No active cooling or ventilation changes are required when swapping the original cell. Overcharge, over-discharge, over-voltage and short-circuit protection circuits limit stress on the cells during normal use. The 4.32Wh energy rating supports extended talk time without excessive temperature rise.

Certified Safety

The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming compliance with quality management, substance restrictions and transport safety standards. These marks mean the battery has passed mandatory electrical and environmental tests before shipment. No additional software, firmware updates or configuration tools are bundled or required for installation. The protection circuitry is self-contained and transparent to the host device.

Questions about this item

How do I install the Estry P0871365 battery in my Nortel handset and which step do people often get wrong?

Power off the handset, open the battery compartment, disconnect the old pack, then connect the new 3.6V 1200mAh unit matching the polarity markings before securing the cover; the step most often missed is verifying the connector orientation to avoid reverse polarity.

What maintenance or replacement will the Estry P0871365 Ni-MH pack need later?

Ni-MH chemistry self-discharges; recharge the 4.32Wh pack every few months during storage and plan to replace it once runtime noticeably shortens after extended cycling.

What limit appears first when the Estry P0871365 battery is used continuously in a Nortel phone?

Sustained talk time drains the 1200mAh capacity until voltage drops below the handset cutoff, ending the call before thermal limits of the 50.43 x 42.54 x 14.4mm pack are reached.
