Lezyne CR2032 Battery - 8 Pack



Make commuting safe.

So, you got a pair of Lezyne Femto Lights and you're ready to start commuting on your bike every night. Femto LEDs last a good long time–60 hours–in Flash mode, but that isn't forever. You'll need some backup power. Lezyne CR2032 Batteries come in an 8-Pack. That should be enough to get you through the spring, summer, and maybe even the fall.

Lezyne replacement batteries come in a machined aluminum tube with rubber end caps for storage and protection from moisture or dirt. The batteries are tested for capacity and quality before they leave the Lezyne factory.

Lezyne CR2032 Batteries are compatible with Femto Front and Rear LED Lights.

Bad batch?

I bought these batteries to use in my power meter as well as my other sensors. I must've gotten a bad batch of batteries because, within a day or two of usage, the battery power ran out and the power meter stopped transmitting data to my head unit. This issue reoccurred with each battery in the pack until I switched back to a CR2032 battery from a more "conventional" battery maker, e.g. Energizer or Duracell. Since then, I've had no further issues. It's possible that this was an anomaly, but thought it would be beneficial for the Backcountry community to know of this particular experience.

These are great to have on hand at all times. I’ve used them in bike lights and watches. No regrets!

What A Deal!

I've used it several times

an 8 pack of batteries that work in my Speed, Cadence and Heart Rate sensor for what I paid for 2 the last time I purchased batteries?!? Sign me up, that is some serious value right there!

Specific Fit

I've put it through the wringer

I have two sets of Femto Drive light pairs and to replace batteries those you will need this version of the CR2032 since they are slightly thicker than store bought versions. Once installed we were back up and lighting it up.

Stock up on power.

Great value, and having a stack of them to keep around the house and in various saddle bags/packs means there's always a battery nearby when the power meter needs a replacement.

They do what they're supposed to. I use em in my Suunto Core Watch and they last a good while
