I am giving this battery one last chance.....weighs way less than oem.....800cca......Optima Batteries 8003-151 34R RedTop Starting Battery

I accidentally drained the battery after leaving car parked one week with no trickle charger......it has not performed well ever since....shorter reserve time and less crank juice.......just bought a new one and will make sure to trickle charge with the optima charging unit.....should be fine since I've had the battery on other cars with good success
