A battery tender is a must have ?
Purchased a low mileage 2002 FLHTCUI last summer. Put a new HD battery in it and ran great all summer. Went to start it after sitting about a month and the battery was totally dead. Do i have a problem or do these bikes require a battery tender when parked for a period of time ? I do not know what to think. Thank you for any replies that i might get.

You have a problem. Tender is a great thing for keeping the battery at peak charge and will likely extend life of the battery. Your battery should not be dead after only a month though.
Here is how I would go about finding your problem. Get the battry up to full charge, most important thing. If it will not hold a full charge, and likely it wont, do not buy a new battery just yet. You need to figure out and fix your problem first, or you will just keep killing batterys. Get yourself an amp-meter and hook it in series with the battery/cable[s]. most go into the negative side as it is safer in regards to arching. Go to fuses and pull one out at a time until the amp-meter drops to a normal range. You just narrowed it down to which circuit the problem is in. Problem is, you still have to find it from there, but as of now, this is were you are at, and If I were you, that is what I would do.

I know my battery is going to be draining because of the alarm, etc. There is a constant drain on the system even when not in use.
I use a Battery Tender whenever I think I am not going to be able to ride for a few weeks ( although I find I am sometimes more optimistic then I should be ) , but especially when it starts getting cold.
My bike was new on the showroom floor, and when I bought it the battery was stone dead from them demonstrating the alarm, radio, etc.! Dealer charged it before delivery and ( knock on wood ) so far still have that same battery in the bike, and when I put it on the tender last week for the first time this year it only took about five minutes for the indicator light to turn green.
I don’t know what kind of accessories you have on the bike, or if you have an alarm, etc., or what kind of draw an ‘02 has vs. my ‘09, but these are the thing you should consider before condemning the battery. IMHO.
