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.

26R is group and size for that Batt. Yes, you might have a small draw on the battery when not in use. Could be in the alt. A bad diode. Use a test light to check for a draw. Take the clip, hook it to the positive battery cable, removed from the battery, and take the pointed probe to the positive post on batt. It should not light at all. If it does, there is a draw. The brighter the light the more drain.
