I must be missing something. Where's the hold-down?
I did for me, but it didn't show when added to my cart, only when I clicked through to check out.
This was a pic I took when I first dropped it in a few years ago. I used the stock hold down.
Besides the additional weight this is a great battery. Maintained my ARB 50 fridge no problem for a couple if days without starting.
I then decided to run a second 31m in the cab in a NLPP. The NLPP is great because its portable, can be used in different vehicles, etc.
If you are patient I've seen these as low as $199. But if they are currently $209 I wouldn't think twice since its such a great battery.
