What buyers say about Energizer CR2450 Lithium Battery, 3v ECR2450, Qty 6
I bought one at the pharmacy for $5.98 and it was really easy to use, but you need to use the process my husband showed you.
I bought some batteries from Cheap Batteries Co., and so far they seem legit, but I will have to wait and see if the % drops too fast.
They now have 3 parallel batteries, the original, and 2 Energizer CR2450's, so there's a good chance the amplifier will work, even though it's over 15 years old.
I bought some batteries from Cheap Batteries Co., and so far they seem legit, have printed expiration dates, and two of them have proper voltages.
I used these for my smartThings sensors for a year and they work great. I bought cheaper batteries to try to save money, but I had to replace them 30 days later.
