AND.....you still haven't told us how old your RT is.......or how old the battery is.

It is highly likely that your battery has just reached the end of it's useful life.
After you get a new battery installed, which has been fully charged first, you need to measure the battery voltage with the bike running.......to be sure your charging system is working.

A healthy battery should easily sit for a couple of weeks without any kind of charger attached.
But if you must, a fully automatic one is required.
The total capacity isn't that important because that is under worst conditions and if it really is automatic, the charging rate won't get anywhere near the max. capacity of the charger.
