I bought a D3400 from summit racing in june 2011 to replace a five year old optima yellow top thats in a show car not a daily driver. The last time I drove the car was on fourth of july and yesterday went to bring the car out for black friday and it diddnt start. I put it on charge and the charger said it was at 5% so I let it charge for two hours then went to check it out and it was at 57% so I left it for another two hours and it says bad battery. I then did a load test and it was less than 6V and says to replace battery. I only got a year out of this battery that I thought was better then the optima.
So my question is, how long are these batteries lasting for you guys? I would like to try out another xspower battery but I feel like I got ripped off.
