I bought a Light & Motion Arc HID headlight system in September 2005. I figure I have used it about 300 hours since then. The battery was advertised to have around 3 hours of power using the low light setting. Well, this year it only lasts about an hour before running out of juice. The problem is my ride home takes an hour and 5 minutes, so I either have to hammer every night or ride the last few minutes with no headlight. Why did the battery life decrease? I figure the answers are either (1) the reduced battery life is normal; (2) I did something to screw the battery (I thought the charging system was idiot-proof); or
(3) the battery is defective and maybe L&M should replace it.
Any thoughts or suggestions are welcomed. I'm getting tired of my nightly time trial.
