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.

- Q & A
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.
- Familiarity: I've used it several times
They do what they're supposed to. I use em in my Suunto Core Watch and they last a good while
