02 viper battery is always dead if i leave it for a weak or so , 3 new batteries in 3 years , dealer has looked at it and stillthe same when you test for a draw at the battery there is none, has any one seen this
 
do you have any accesories wired in? Maybe a electric shield? Some aftermarket wiring contains diodes, resistors or capacitors that will drian the battery even if the accessories arent connected. if you have a digital or analog meter with a ampmeter funtion try testing the battery load with the the key off. you should not have a draw on the wiring.

You can always try a optimate charger/condiitioner. I have 7 sleds (6 with accsories) they range from a 97 sx 600 throu 04 viperr and warrior. all are on the original battery except the 88 inviter. I only occasionally use the optimate on the warrior.
 
You are probably leaving your key on and using the kill switch to shut off the engine. The key still powers the fuel gauge when the engine is off.
Some of those batteries were duds but not likely 3 in a row.
 
I am also a fan of that optimate charger, and keeping that on when you are not running your sled.
Do you have a period during the year where the battery sits unattended for a month or more? A battery that gets left uncharged for even a little while may not hold a charge correctly ever again.

If you use a charger but it is a conventional one, you could be over charging it which will ruin it also. and yes like above use the key to turn it off.
