Like I said when the service stations were all full service they were everywhere, but with the mini marts and self serv. stations that dot the landscape I haven't seen any one with the battery water fill bottle or for that matter any way to fill a radiator in case it over heat other then if you want to buy plastic liters of water bottles. Add to that the claim by most battery manufacturers that their batteries are "Maintenance Free", so people don't take care of their batteries like in the "Old Days".

Like X5SND stated the bottle only hold a couple quarts of water. The handle is just big enough to fit one's hand in it.
