My dad asked me for help with his. I'd bought several Maxell CR1620 for him a few years ago for his 2008 Nissan key remote. They made it really, really small so that the electronics weren't much larger than a normal key base, but man that thing is tiny, not terribly powerful, and eats through batteries like crazy.
I remember he paid for a battery maybe last year because my mom stashed away the batteries I got and couldn't find them. But they found them and asked me to help when it didn't work last weekend. I didn't have a tester or voltmeter, but we tried every single battery and none worked except the one in one remote. Looking at the date code is was clearly a Maxell CR1620 that I got for them a few years ago. My mom barely uses that car so her remote was barely used. But all of the other ones didn't do anything. I was kind of frustrated because the date code showed it was made March 2018 and the package says they expire in 2023.
Just venting. I ordered another pack (5 for maybe $4) of these things but shipping is going to take a few days. I get that these also tend to be more expensive than larger and more common CR2025/CR2032. I get that they use them to be thinner, but a larger one would have been nicer for a longer use, more power, and longer storage life.
