If you are running a real gel cell battery (not AGM or Lithium) that may be your problem.
Gel batteries have a very different charging program then the usual batteries used on bikes and they also need a specialized charger. They have been typically used in the past on race bike total loss systems, but IMHO are really a poor choice for a street bike.
The AGMs work very well and lots of people use them. I am currently running a lithium-ion battery with a Typanum reg-rect on my TR6C. So far no problems since June, but it is experimental.
What is the exact information on your battery..brand name and model number? It sounds like it is rapidly self discharging which is a prelude to failure.
Start by testing your battery. Charge it up to a least 12.8 volts no load, let it sit for an hour and check it. Now let it sit for a couple of days and check it again.
