M5070A is the universal Philips battery, fits OnSite, Home, AND FRx. We maintain ONE battery SKU across 14 buildings instead of three separate inventories. 4-year shelf life. Snap-in tool-free installation. Most affordable Philips replacement option.

Reliable Philips battery with cross-model compatibility. One star off because non-rechargeable means at 4 years you replace, no refurbishment option. But cost per year over the 4-year life is reasonable.
