Just bought a new battery 1 month ago. Everything has been running fine. Parked the bike since the weekend and fired it up today, only to find the bike clicking when trying to turn it on. At first i thought it was about to turn over but after a few more attempts it was only clicking and the lights were dimming. Used a charger to charge the battery and plugged it back in. Used a voltage multimeter and these are the values i got;

Sitting = 12.90 volts
Idle = 14.30 volts
start = 9.90 volts
RPM@4K= 13.95 volts

When i turn the bike off it starts at 13.40 volts and goes down 0.01 volts every 3 seconds till it equals out to 12.90 in about 4 minutes.

Read through a few forums but couldnt really find anything concrete. Any help on what the cause of the sudden dead battery be?
