I have gotten 3EE batteries in the past at my local automobile battery/electric shop, and more recently at Batteries Plus. The former says he likely won't be able to even order one, and the latter has none in stock, and they show none in stock at local stores. I asked if they could order one, they say the 3EE's are on "back order". with no estimated delivery date. Does anyone know of a reliable source where they're recently purchased a 3EE battery ?? Most appreciated; thank you..
