Battery needs cap for classic car

Arrived in 2 days. While not intended to fit my 54 Ford, I mounted it at an angle that worked for the factory top hold down piece. I don't understand why Optima or other vendor doesn't offer 6 volt battery cap or box to better secure the battery in classic cars. Otherwise the battery has been flawless in the 6 weeks or so that I've owned it.

Great battery for antique cars

I have been using these batteries in my antique cars for years. Right now I have 4 6-volt and 3 12-volt optima red top batteries in use. They don't discharge as quickly wet batteries when sitting due to non use. I have one car which I had to use tractor batteries due to the vibration destroying regular batteries. Even with the tractor battery, I could only get 2 maybe 3 seasons on a new one. I purchased this Optima to replace the one in that car. It finally went bad after 10 years and 5 months. Well worth the money.

Optima 6V redtop batteries are a good value and get the job done

I've been using these 6V Optimas in my 2 Porsche 356C coupes for over 15 years now. I have yet to find a better 6V battery for these cars, as they don't leak and have plenty of cranking power. I have had them last anywhere from 9 to 11 years, when kept on a battery minder (chip-controlled charger) when the cars are not being driven. Amazon's price is hard to beat as well.

Best upgrade for your old car!

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!!

Batteries Are the Best!

So I've had two of two of these paired (12 volts) in my off road car for 11 years! They finally gave up, wouldn't fully charge anymore. That's ok, 11 years is amazing! I received the two new batteries and they are 3/8" taller than the original ones, that normally wouldn't be a big deal for most applications, but my battery tray was made to hold the two batteries laying on their side and sized to fit snug. So needless to say I had make mods. Still the battery I've ever used, no corrosion!

Is this battery good..

Is this battery good...well let me tell you...I was out cruising with some friends and we stopped for a beer and some pizza...Two or more hours later when I went out to my 55 Thunderbird with its 6 volt system to go home, it was sitting there with the lights on! I got into the car, and it started promptly...

Got my new battery and it’s great omg the power in this thing it’s incredible start up

This things it’s a 6v beast omg this power start up it’s incredible many Batteries gone thrust this old jeep,and wow this is the first one that turns this motor on on the first strike ,, thank you and I highly recommended this product it a peace of mind % wow It’s completely safe and no unsafe areas all cover with safety in mind ..

Excellent choice for a 6V battery

The 6 v Optima is very powerful w/ 800 cranking amps. The odd shape actually has been an advantage for my applications and many companies offer special battery mounts for this particular battery. Since it is sealed, it can lay on its side as well. If a person is crafty, fitting the battery to most 6v applications is not a problem. I am using one in my front surly Porsche and another in a 1953 VW Bug. Neither application has damaged the ability to mount a stock style factory battery for originality. No holes needed to be drilled to mount them. Shipping was free and they arrived on the date promised. It

Replacing overpriced yellow top optimas in 2008 VW Eos.

I bought this product to replace the batteries in a 2008 VW Eos, Volkswagen wanted 550 for a set of new yellow top batteries, but after doing all my research, found that the yellow tops where known to fail because of the extra plates they placed inside of battery. These went into the car just as easy as the yellow ones came out, and not a single issue with them yet. Very pleased I found these replacements and for the price cant be beat. Highly recommend.

Plenty of power

I bought this for my 1934 automobile with a 6 volt positive ground system. It has plenty of cranking power and turned the straight 8 engine over MUCH better than the conventional batteries from local stores I had been using. Worth every penny. Cannot as yet give a rating for longevity, but I am following the charging instructions and am very happy with it so far. Make sure you get the right battery maintainer, specific for these types of batteries.
