NShi IS900 replacement battery

The NShi IS900 is a 3.7V lithium polymer battery rated at 5250mAh and 19.43Wh. It serves as a direct replacement for the original power pack in Pax A920 and A920C devices. The cell chemistry matches the factory specification for safe integration.

Capacity and headroom

The 5250mAh capacity restores the original runtime for daily transaction processing on the Pax A920 series. It supports typical shift-length workloads without mid-day recharging. Heavy continuous printing or maximum screen brightness will deplete the reserve faster than light use.

Thermals noise and power draw

Lithium polymer construction generates minimal heat during normal charge and discharge cycles. The battery operates silently with no moving parts. Power draw follows the device's own management profile, adding no extra load beyond the original design.

Questions about this item

Will the IS900 battery work inside my older Pax A920 terminal without any modification?

The IS900 is listed as a direct replacement for both the Pax A920 and A920C, so it fits the existing battery compartment and connector without modification.

How can I verify the IS900 is delivering the rated 3.7 V and 5250 mAh after I install it?

After installation, power on the terminal and check the battery information screen; it should report 3.7 V and a capacity close to 5250 mAh or 19.43 Wh.

Does the package include only the IS900 battery, or are tools and cables also supplied?

The supplier data lists only the IS900 lithium-polymer battery itself; any opening tools or charging cables must be sourced separately.
