Big Box for big badest battery for the price H8!

Fitted H8 battery, only box I have found that does I put thick rubber pad in box bottom to dampen vibration lasts longer starts better more reserve power and recharges faster than group 27,29 or31 marine dual purpose batterys in recreational boats of all types and sizes.
