Certified safety under load

Overcharge, over-discharge, over-voltage and short-circuit protection circuits guard the cell during panel operation. The pack carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications, confirming compliance with international transport and substance rules. Normal standby and alarm cycles run within the designed thermal envelope.

Compact form fits the panel chassis

Dimensions of 50.0 x 43.0 x 11.64mm and a weight of 77.0g match the factory battery cavity. The two-wire connector aligns with the existing header, so installation only requires opening the panel cover and plugging in.

Questions about this item

How is the Estry 2600 mAh 3.7 V battery installed in the IQ Panel 2 Plus, and what step do people often miss?

Power down the panel, open the rear battery compartment, disconnect the old pack, connect the new pack matching the polarity, close the cover, then power up and verify the panel reports 11.1 Wh.

What maintenance or replacement will the Estry 2600 mAh 3.7 V pack need later?

The sealed lithium pack has no user-serviceable cells; when run-time noticeably shortens, replace the entire 50.0 x 43.0 x 11.64 mm unit.

What limit appears first on the Estry 2600 mAh 3.7 V battery during sustained backup use?

The 2600 mAh capacity sets the total energy at 11.1 Wh, so extended outages will drain the pack until mains power returns.
