When “5 Years” Turns Into 7, 8… Even 10 Years!

“How long do the batteries last in our flow meters?”

Our standard answer has been conservative:

Approximately 5 years under normal use.

But recently we had two meters come back for battery replacement that lasted much longer! One customer’s battery lasted about 9 years. Another customer’s water meter ran for roughly 7–8 years before needing service. We asked Garret (the original owner of MIC Meter) about these two long-lasting battery situations. He told us that 7–9 years of battery life is actually pretty normal in real-world applications, but he always preferred to quote a more conservative estimate because operating conditions vary from installation to installation.

Why Do Our Batteries Last So Long?

A big part of it comes down to how the meters are designed.

Our flow meters are built to be:

• Efficient

• Simple

• Reliable

• Easy to read without unnecessary power draw

We’re not trying to cram flashy features, Wi-Fi modules, bright backlights, or power-hungry electronics into these units. Instead, the focus has always been on dependable long-term operation in the field.

Real-World Reliability Matters

When a flow meter battery lasts nearly a decade, it means:

• Less maintenance

• Less downtime

• Fewer service interruptions

• Lower long-term operating costs

For many customers, the meter simply gets installed… and quietly does its job year after year.

That’s exactly what we want.

A Conservative Rating — By Design

We’ll probably continue to state “about 5 years” on the website because we’d rather under-promise and over-deliver.

Battery life depends on several factors, including:

• Usage frequency

• Environmental conditions

• Storage conditions

• Temperature extremes

• Installation specifics

But it’s always rewarding to hear from customers whose meters have been running strong for nearly a decade before finally needing a battery replacement.

Built for the Long Haul

At Midwest Instruments & Controls, LLC, we believe industrial equipment should be designed for durability and longevity — not disposability. These recent battery replacements were a great reminder that thoughtful engineering and quality components still matter.

And yes… we’re pretty proud of that. 🙂
