Replacement battery for Simon Xti panels

The Estry 6.0V 2500mAh Ni-MH pack matches the original voltage and capacity for the Simon Xti alarm panel. It measures 84.28 x 51.92 x 16.88mm and weighs 220.0g. The unit delivers 15.0Wh and carries ISO9001, RoHS, CE, UN38.3 and MSDS certifications. Confirm the model and part number before purchase.

Steady output during long standby

Ni-MH chemistry provides stable voltage across extended standby periods typical of security panels. Overcharge, over-discharge, over-voltage and short-circuit protections help maintain capacity through continuous trickle charging. The 2500mAh rating supports the panel’s monitoring and communication cycles without rapid voltage sag. Certifications confirm compliance with transport and environmental standards.

Direct fit with screw terminals

The pack dimensions match the factory battery compartment for a direct mechanical fit. Installation requires connecting the existing leads to the corresponding terminals; polarity must be observed to avoid damage. No soldering or adapter cables are needed. The main risk is ordering the wrong part number, so verify compatibility against the panel label before fitting.

Questions about this item

Does the 6.0 V Ni-MH pack generate noticeable heat during continuous monitoring duty?

The 2500 mAh cell is rated at 15.0 Wh, and the supplier confirms built-in over-charge, over-discharge, over-voltage and short-circuit protection to limit excess current and keep temperature stable.

What existing hardware must be in place for this battery to function?

It is a direct replacement for the Simon Xti Alarm Panel; the panel itself and its original wiring harness are all that is required.

Will the 84.28 x 51.92 x 16.88 mm dimensions fit the original compartment in an older Xti unit?

Yes, the pack matches the factory footprint and weighs 220.0 g, so it seats in the same bay without modification.
