Review on 10 Pack CELEWELL CR2032 Lithium Coin Cell Battery - High Capacity 230MAh, 3 Volt Button Battery For Devices - ECR2032 Replacement - 5-Year Warranty (Not Suitable For Thermometers) by Ruth Haiar

I bought these batteries for an elementary STEM enrichment class that I teach. These were inexpensive and perfect for our circuits project. They came packaged in a box so it is store the remaining batteries of another project. Shipment was prompt and I appreciated the email reminder about the dangers if swallowed. The batteries in my sample project have last 3 days so far with the LEDs constantly on. I can’t speak to the rest of the batteries since I sent them home in the student projects, but they all worked perfectly in class while the students were working. I will buy thes again when I run out.
