Also is your starter in good condition?
Cables all new- thanksHow old are your battery cables? They can deteriorate under the insulation to the point where they cannot cope with cranking amps.
I do have kill switch- always a good idea, and about to swap my cheapo solar trickle charger to something more heavy duty!That's a very good point, i fitted a new starter last year and the difference in cranking speed and power is night and day on the same battery.
Also something else to bare in mind, a battery will hold a charge far far longer if the Neg or Pos is entirely disconnected when the car is not in use.
I have one of those battery cut off things fitted and the car sits in storage over winter for approx 5 months, but it has started the car for the last few years no problem, even before i renewed the starter motor!
