3.6V 600mAh Ni-MH chemistry

The single specification that decides fit is the 3.6V 600mAh nickel-metal hydride chemistry in the stated dimensions. If the original battery label shows a different voltage, capacity or chemistry, this pack will not work.

Questions about this item

Will the 42.45 x 29.77 x 14.37 mm pack fit the handset battery compartment?

Yes, those exact dimensions match the original EL42408 pack so it seats correctly in the same cavity.

How do I install the pack without damaging the connector?

Align the two-pin plug with the socket, press straight in until it clicks, and avoid bending the pins sideways.

When should I replace the 600 mAh Ni-MH pack?

Expect roughly one year of daily charge cycles; swap it when talk time drops noticeably below the original runtime.
