Direct replacement for Ativa handsets

This Estry D5702 battery is a direct replacement for Ativa models D5702, D5772, D-5702 and D-5772. It matches the original 3.6V 700mAh Ni-MH specifications so cordless phones and compatible devices regain their rated talk and standby time. The pack measures 47.0 x 32.0 x 11.5mm and weighs 63.0g.

Low self-discharge Ni-MH chemistry

Ni-MH cells hold charge for months without the memory effect of older chemistries. Built-in protection guards against overcharge, over-discharge, over-voltage and short circuit, keeping the pack stable during daily charging cycles. The 2.52Wh rating stays within postal and airline limits for hassle-free transport.

700mAh capacity decides fit

Capacity is the single figure that determines whether this pack fits your power budget; a handset needing a higher milliampere-hour rating will drain faster, while a lower-draw device simply charges less often. Verify the model list before ordering — no other specification overrides this number.

Questions about this item

How do I install the Estry D5702 battery and what step is often missed?

Match the 3.6V 700mAh pack to the D5702 or D5772 device, align the connector polarity, and secure the 47.0 x 32.0 x 11.5mm pack; the step often missed is verifying the part number on the old cell before fitting.

What maintenance or replacement will the Estry D5702 Ni-MH pack need later?

Expect a gradual capacity drop after several hundred charge cycles; plan to replace the 2.52Wh pack when runtime no longer meets your needs, typically after one to two years of daily use.

What limit appears first during sustained use of the Estry D5702 battery?

The 700mAh capacity sets the runtime ceiling; under continuous load the 3.6V output will sag once the 2.52Wh energy reserve is depleted, ending the operating session.
