modern batteries stop taking a charge ten percent per year...so look 'pon the top of the battery...the "knock-off" labels will indicate the month and year of the batteries first charge...it's all downhill from there~...seriously you may have a parasitic drain...you could follow eric the car guy's video~ http://www.youtube.com/watch?v=KF1gijj03_0
