Resideo ProSeries: Batteries Used and Why

In this video, John from Alarm Grid explains why the PROA7 and PROA7PLUS panels seem to have different types of batteries. When the ProSeries panels were engineered, they were made to work with a two-cell approximately 5,000 mAh battery. This battery provides the required standby power in the event of a power failure. The UL requirement is that the battery be able to power the panel for at least 24 hours.

At the time the panels were released, due to COVID-19 and supply chain issues, Resideo (the manufacturer of the ProSeries panels) was unable to source the two-cell batteries. For that reason, they were forced to release them with a three-cell approximately 7,500 mAh battery. Obviously, this battery would also supply the necessary power to support the panel for at least 24 hours during an extended power outage. However, this is not the battery that was intended to be used with the panel, and I'm sure it was also a more expensive option, so once the supply chain issues were resolved and the original two-cell battery was available, Resideo stopped offering the higher-capacity battery option. This is why, if you purchased a panel when they were first made available and you've since purchased a replacement battery, the replacement looks different than your panel's original battery.
