OPTIMABatteries High Performance 6V RedTop Sealed AGM Car, Truck and SUV Starting Battery, 800 CCA, SAE Terminal, Maintenance Free, Versitile Mounting, 6 Volt

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!!

Best 6 volt battery I've ever bought and love to smaller size.

Incredible charge life and cranking power.

This battery is expensive. I could have bought 3 normal!? lead acid batteries for the price that I paid for only one Optima battery. Why did I do that? I have a 1951 Ford that had a 6 volt system when it was new. I restored it and left it as original as possible. My current lead acid battery is 5 years old. It was leaking and causing corrosion on both battery terminals as well as eating the paint off my battery holder. I participate in a few old car restoration chats. Many, many of the other folks that have tried the 6 volt Optima assured me that I would not be sorry that I spent 3 times more money and I should go ahead a purchase this battery.I bit the bullet, so to speak, and ordered the battery. I had already cleaned my cables and repainted my battery holder while waiting for the battery to arrive. I strapped it in with bungie cords and turned the key. I spins the engine as fast as a 12 volt. The car had been setting long enough for some of the gasoline to evaporate out of the carburator. With the old battery, I normally squirted some starter fluid down the carb before even attempting to start it. I just wanted to see if this battery is a great as I have been told.The only thing that I can find to complain about is the size of the battery. I had to make a holddown for it. I cut up some sheet metal, bent it and welded it together in about an hour. I am now a happy owner of a battery that I think that I can trust. I'm also told that it will never leak and ruin my cables or battery holder.Ron

good product

Had batteries for a year and they stopped charging. Contacted support in June. Even though they sent me an email to rate the return of the batteries, I was not contacted back for help. I called again in August and go through a series of emails until they send me an email in late August with an attachment telling me to only charge on the terminals, not the bolt attachments. Then crickets. I email for an update in mid September, only to be shoved back into the que and have to deal with lazy people who don’t look my case up. I send screen shots of the email exchanges and an Optima customer service supervisor calls me to inform me that I was using them for the wrong application (deep cycle instead of starting) and my warranty is void. I keep expressing my dissatisfaction (no yelling or cussing) and suddenly the call disconnects with no call back. Why did this take nearly three months to tell me that?

I have a 1940 Dodge that takes 6voltI checked out all automotive shops in my townno one carried this size.Easy to installWarranty didn't receive one, I wish they would put one in the boxHappy that Amazon carried this sizeVery happy with purchase didn't take long to receive.

Optima batteries for me last a long time. Average life of 7 to 10 years. I have them in all vehicles. Very important to make sure it fits your vehicle. Take measurements of battery compartment to be sure of fit.
