Hard to remove and re-connect the nylon straps on my new Quantum RW28 house batteries. I replaced these with white cable ties -- available at Home Depot, Lowes, etc. Thread the cable tie through one side of the slot that the nylon straps used.
I've had dozens of boats, RVs and cars through the years on which I have done this trick. Makes removing batteries so much easier. Just snip off old cable tie if you need to remove battery and replace with new one.
I just bought a brand new Quantum RW28 -- this cable tie was my first mod!
