Battery Drain: LifeSafer L250 vs. Intoxalock 1001A
Third-party testing conducted in July/August 2023 found that the LifeSafer L250 draws 4x less battery drain while the vehicle is off compared to the Intoxalock 1001A.
This difference matters because IIDs continue drawing power from the vehicle battery even when the car is turned off. Over time, excessive parasitic battery drain can contribute to dead batteries, especially during cold weather or when a vehicle is not driven regularly.
For drivers already dealing with the stress of a DUI program, a dead battery can create additional problems, including missed appointments, lockouts, or potential compliance concerns.
LifeSafer’s lower battery drain helps reduce the risk of unexpected battery issues and gives drivers additional peace of mind during their IID program.
LifeSafer also includes features that further protect the vehicle battery, including:
- Automatic sleep mode when the vehicle is off
- Programmable warm-up settings up to three times per day
- Efficient internal heaters designed for cold-weather performance
These features are especially important for drivers living in colder climates or for people who do not drive their vehicle every day.

Which Is the Best Ignition Interlock Device: LifeSafer or Intoxalock?
LifeSafer is the better IID for most drivers because it offers less battery drain, no deposit in many cases, a simpler blow pattern, and transparent pricing. Third-party testing found that the LifeSafer L250 draws 4x less battery power when the vehicle is off compared to the Intoxalock 1001A, and LifeSafer’s straightforward pricing and user-friendly design can help simplify the ignition interlock process.
When comparing the overall experience of using an IID every day, the details matter. Drivers want a device that’s easy to use, reliable, discreet, and backed by responsive customer support.
LifeSafer stands out because it combines several advantages into one program. The device itself is compact and user-friendly; the blow/hum testing pattern is simpler than the blow-inhale-blow pattern used by Intoxalock, and third-party testing showed significantly lower battery drain while the vehicle is off.
Pricing transparency is another major differentiator. LifeSafer provides clear billing information and, in many cases, does not require a deposit, helping drivers avoid surprise charges during an already stressful process.
Customer support also plays a major role in choosing the best interlock device. Drivers may need assistance with installation scheduling, monitoring appointments, lockouts, or compliance questions. LifeSafer offers 24/7 customer support and convenient online scheduling to help simplify the process.
To maintain an objective comparison, it’s important to note that Intoxalock does have some advantages. Intoxalock has a larger overall installation network, and some drivers may prefer the one-button design.
However, for most drivers comparing Intoxalock vs LifeSafer, LifeSafer’s advantages in battery protection, pricing transparency, easier blow pattern, customer reviews, and user experience outweigh those differences.
