## Product: BACtrack S80 Breathalyzer
**Brand:** BACtrack

Hey! If you're curious about the battery life of the BACtrack S80 Breathalyzer, here's the scoop: the manufacturer says you can usually get around 1,000 tests on a single set of AA batteries. 

Keep in mind, though, that actual battery life can vary depending on how you use it and the environment it's in. 

Something to keep in mind is that it's powered by two AA batteries. From what we've found, using high-quality batteries like [lithium batteries](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dlithium%2Bbatteries%26tag%3Dssw.ans.tx-1-20) or [premium alkaline batteries](https://www.shopsavvy.com/redirect?url=https%3A%2F%2Fwww.amazon.com%2Fs%3Fk%3Dpremium%2Balkaline%2Bbatteries%26tag%3Dssw.ans.tx-1-20) can help stretch the time between battery changes.

On a related note, while it's not really about battery life, the device does need to be calibrated every 6 to 12 months to maintain its accuracy. If you skip this step, it might not be as accurate, so it's something to plan for.

And just a small heads-up: some folks have mentioned a 'FLO error' that pops up if you don't blow into it quite right. So following those instructions can definitely help with getting consistent results.

Overall, the BACtrack S80 does seem like a good option, but make sure to keep up with battery replacements and the occasional calibration to get the most out of it.
