Comes with 4 year warranty too.
Best stick a bit of old inner tube or similar dense thin rubber onto the underside of your batter box lid, you don't want it shorting out and it is very close.
You will also need crimped battery terminals as there is no headroom for the ones with screws, unless you use grub screws wound down flush

Alpha Batteries have an ebay webshop "the battery man"
and they arrive very well packed. Recommended.
