Bought this battery for a 1931 Ford with 6 volt system.
Had been using old style wet cell batteries, and always hated having to constantly check the levels, etc. Seemed very fragile too. Overcharge, and you boil it out. Let it get too low and it's toast. Not cool.
Years ago, put an Optima red top battery in a newer Jeep, and have been VERY happy with it. So, when the old Ford needed a new 6 volt battery, I was pleased to find that Optima made a battery for that too. Amazon has the best price anywhere ($115 SHIPPED!!) when I needed one, so eagerly ordered. Battery was shipped encapsulated in expando-foam inside a heavy duty cardboard box. VERY well packed, and arrived without a scratch. Was also surprised to see the manufacture date was only weeks before I got it. Nice and fresh!
A little confusion as to where it was made. The battery says "Made in U.S.A." on the case, yet there was a cheesy looking sticker on top that said "Made in Mexico". Well, that was easy, just peeled off the sticker, and Whalla!! Made in USA.
The Ford Model A battery tray is under the driver's side floorboard, and the stock batteries are a pain in the neck (and back, arms, hands, etc.) to replace. The Optima battery is much lighter and smaller than the stock batteries and easily fits in the tray with room to spare. In fact, way too much room to spare. Had to find a solution to hold it on the tray and keep it from falling out of the car. Ended up buying the nice bracket made just for mounting Optima batteries in Model A's, available from Brattons.
The Optima battery starts the car with ease. People that have heard a 6 volt car crank over know the labored sounding cranking speed well. The Optima 6 volt battery cranks the car over almost like a 12 volt car! It really has no trouble at all starting the car, and you can even start the car with the lights on!
The Optima says 800 CCA (Cold Cranking Amps) while the stock battery says 600 CCA, so there is a big difference right there. Odd since the Optima is so much smaller than the flooded batteries.
Without a doubt, the Optima battery is the best upgrade done to the old car so far. Worth every cent and then some. No longer have to worry about, "Will the car start??" One less thing to worry about!!
