Estry 79 Lock Replacement Battery

This Estry battery replaces the original power source for the 79 Lock system. It matches the factory specifications for voltage and capacity to restore reliable operation. The pack is built with Ni-MH chemistry and includes protection against overcharge, over-discharge, over-voltage and short circuits. Certifications include ISO9001, RoHS, CE, UN38.3 and MSDS.

2700mAh Capacity and 2.4V Output

The pack delivers 2700mAh at 2.4V for an energy rating of 6.48Wh. This capacity supports the lock's normal duty cycle and standby current draw. Runtime scales with actuation frequency; very high traffic or extreme temperatures will reduce the interval between charges. The physical envelope measures 51.5 x 33.8 x 17.0mm and weighs 104.0g.

Direct Swap for Part 132-512886

This unit is a direct replacement for part number 132-512886 used in the 79 Lock. The upgrade is worth it when the original pack no longer holds a full charge or shows voltage sag under load. It is not suitable for locks that require a different voltage, connector layout or form factor. Buyers needing higher capacity or a different chemistry must seek an alternative design.

Questions about this item

Will the 132-512886 pack fit my existing 79 Lock without modifying the housing?

The replacement measures 51.5 x 33.8 x 17.0 mm and weighs 104.0 g, matching the original 79 Lock battery dimensions so it slides straight into the same compartment.

How can I confirm the 2.4 V 2700 mAh pack is delivering full capacity after installation?

A healthy pack reads about 2.4 V at rest and powers the lock through multiple cycles; if the lock operates normally and the voltage holds under load, the 6.48 Wh capacity is performing as specified.

Does the box include the 132-512886 battery only, or are screws and wiring harnesses supplied too?

The package contains the Ni-MH 2700 mAh 2.4 V battery pack; mounting hardware and wiring are not included and must be sourced separately if your lock requires them.
