The Hidden Cost of Dead Batteries

16 September 2019

Home security systems have dozens of battery-operated sensors: door and window sensors, glass break sensors, motion sensors, smoke detectors and more.

Inevitably, one of these batteries starts to run out. Then another. Then another. It’s an annoyance. The alarm system may ‘complain’. Replacing a battery may be easy or it may require purchasing a special battery and climbing on a ladder. Some people have a service contract, but there might be a “deductible” cost for this service call.

Because of this, some people replace the depleted batteries and some decide to just disable or disregard that particular sensor.

The problem is that with every disabled system, the value of the home security system is reduced. Last month, it protected give rooms, now it protects four. Last year, it was monitoring smoke, now it does not. This is, of course, a risk for the consumer. But the hidden risk is to the security provider. It keeps collecting monthly fees for a system that is becoming less and less valuable to the customer. Ultimately, some customers decide that it is no longer worth paying these monthly fees.

The lifetime revenue loss to the service provider is orders of magnitude higher than the cost of a battery. But then again, proactive visits to the customer to replace batteries have drawbacks as well.

Wireless power can stabilize this slippery slope. By ensuring that all sensors are fully charged, the value of the home security system does not decrease. Wireless power, in this case, helps protect the homeowner, but it also helps protect the revenue for the service provider.
