Works fine and worth the price
"I've used CR2016s from Energizer, Sony and Maxell for years and thought I'd give the Renata brand a try. Its low price didn't hurt either. I found the runtimes on a keychain light to be very similar to the other name brand batteries. The Energizer is rated at 100 mAh, while the Renata, Sony and Maxell are all supposed to be 90 mAh. It's no wonder the latter three do not last quite as long as the Energizer. The Energizer and Sony cost more than the Renata and Maxells though. The Renata gives me a fourth option for when I need a button/coin battery in the future."
