battery is dead quickly on 2009 Honda Civic Hybrid

if lights, even a dome light gets left on for 1/2 an hour, the battery goes completely dead- shouldn't the battery last longer than this? car had just been driven for 2 hours straight at 65mph just before this happened. it has happened a coupla times-just curious.

This happened to me too. Then the engine runs roughly for a while as it charges the battery in the front. It is weird but i can confirm this happens!
yes, sounds suspisious that the battery is not holding a charge. have it checked for load ability.

thanx for the quick response ;>)
