The idea of a tender is to keep the battery charged at all times.

I have gone through several of them on my car in the racecar hauler. Nothing like going out to pull the car out in the spring and find that the tender failed and the battery...and OBD readiness...are stone dead.

I bought one of these (NOCO GENIUS2D on-board charger) on Black Friday sale for $29, but haven't had a chance to install it yet:
