The Honeywell Home PROA7BAT2 is a backup battery for the Honeywell Home PROA7, the Resideo PROA7C, the Honeywell Home PROA7PLUS, and the Resideo PROA7PLUSC. This rechargeable battery provides at least 24 hours of backup power in the event that AC power becomes lost or disconnected.
Normally, the ProSeries 7" All-In-One Panel runs on AC power from a plug-in transformer. The backup battery slowly stores power in the background while the panel is running off AC power. Once AC power is lost, the backup battery automatically kicks in and keeps the system running. You can expect the PROA7BAT2 to keep the system running for at least 24 hours.
As is the case with any battery, the Honeywell Home PROA7BAT2 will slowly lose its ability to store a charge over time. Once the battery is unable to hold a sufficient charge, the system will display a low battery warning, and you will need to replace the it with a new one. Most PROA7 users can expect to go at least five (5) years without a battery replacement.
Please note that the PROA7BAT2 is the default battery included with the ProSeries Panels as of March 2021. It replaces the PROA7BAT3, which was the previous default battery. The difference between the two is that the PROA7BAT2 has a lower power rating of 3.6VDC, 5200mAh, compared with the PROA7BAT3 power rating of 3.6VDC, 7800mAh. Both the PROA7BAT2 and the PROA7BAT3 are advertised to provide at least 24 hours of backup power. You can visually identify each one, as the PROA7BAT2 is the smaller 2-cell pack that plugs into the smaller battery port, while the PROA7BAT3 is the larger 3-cell pack that plugs into the larger battery port.
