Lithium Power

Batteries last 5 years and provide protection in power outages

Lithium powercells for
long-lasting protection

SimpliSafe wireless sensors run on lithium batteries, ensuring your security system is running even when the electricity grid fails.

Because lithium powercells provide long lasting power, you don't need to think about replacing them for up to 5 years.

When you do need to replace them you can easily purchase them at your local drugstore or from us.

Power outage protection

SimpliSafe offers you protection even when your electricity grid fails you. During a power outage, the Base Station pulls power from its rechargeable backup battery, so your alarm system remains fully functional for up to 24 hours.

Once power is restored, the Base Station will re-charge its backup battery, so you don't have to worry about replacing them before the next power outage.
