Stop in for a cup of coffee

Good morning,

Is it right of me to assume this battery was delivered May - 2018 ? But what does 26R mean ?

I tried to start the car today, and the battery was totally dead. It seems to me it does not hold the power over a bit of time, like a week or more. But it is awfully fast to charge again, and the engine spins fast and starts easily.
I need to put my amp meter between the battery post and minus clamp and see if anything is going on there with all the consumers switched off. If I can read anything I have a leak, so that will explain why the battery goes dead.
