I put these in my emergency torches, and I know they'll be ready to go when I need them, thanks to the PCB.
The extra cost is minimal for the added protection. I recommend these over bare cells to all my friends.
These kept their charge for 6 months in storage. I was amazed when I tested them and they still showed 3.9V.
I use them in my remotes, clocks, and flashlights around the house. They last a long time between charges.
I learned my lesson with unprotected cells. These are the only kind I'll buy for my sensitive gear now.
