I've been having issues with my car constantly need to have a jump in order to drive it. i bought a new battery and its still on. If I jump start, van runs fine for hours but once I turn if off it odes not start.
It could potentially be the battery cables, if the starter cable doesn't have a good connection, or it may have too much voltage drop not allowing a strong enough current. Some factory made cables don't use 100% Copper, they use Aluminum Copper Alloy which has 60% conductivity on top of the natural voltage drop. We do offer high quality cables, the thicker the cable the less voltage drop, we also use 100% Copper, and our Copper is twisted internally, allowing optimal conductivity. I recommend getting a thicker cable with 100% copper for your starter cable.
