Direct replacement for Aastra handsets

The Estry PM38BAT is a nickel-metal-hydride battery built to match the original specifications for Aastra DECT handsets. It fits models PM38BAT, BE3872, MOD B PLUGIN, BE900FA and BE3850 without modification. The pack delivers 3.6 V and 700 mAh for cordless phone operation.

Voltage and capacity match the original

Rated at 3.6 V and 700 mAh, the cell provides 2.52 Wh of energy in a 45.6 x 31.3 x 10.6 mm form factor weighing 61.0 g. These figures correspond to the factory battery, so the handset charges and reports capacity correctly. No adapter or firmware change is required.

Steady output during long calls

The chemistry maintains a stable voltage curve across extended talk time rather than sagging after a short burst. Overcharge, over-discharge, over-voltage and short-circuit protection circuits preserve cycle life under daily charge cycles. The pack is certified to ISO9001, RoHS, CE, UN38.3 and MSDS standards.

Questions about this item

How long will the 700mAh capacity actually run my handset?

The 700mAh rating at 3.6V delivers 2.52Wh; talk and standby times depend on the handset's power draw, so runtime will match the original battery's performance.

What connector does the battery use and will it fit the handset's socket?

The replacement uses the same plug-in connector as the original PM38BAT pack, so it mates directly with the handset's battery socket without adapters.

Will the 45.6 x 31.3 x 10.6mm pack fit inside my handset's battery compartment?

Those are the exact dimensions of the original pack, so it fits the same compartment and weighs 61.0g.
