User questions & answers

Question:	This optima charger how long is the warranty, thanks
Answer:	We provide 18-Month Hassle-Free Warranty, 24-hour friendly customer service and 100% customer satisfaction.
Question:	Are the battery terminal clips/clamps plastic
Answer:	Yes. This smart battery charger supports charging all types of 12V lead-acid battery, including AGM, GEL and STD. After searching the optima yellow top battery on market, most of optima yellow top batteries are AGM, which can be charged by this smart battery charger.
Question:	Does it work with Optima battery only or work with all brands
Answer:	There is a difference between a dead battery and a drained battery. A completely dead battery is not safe to charge. I believe this device needs a battery with at least 6 volts to recognize it as a battery and begin to charge it.
Question:	Are the clamps made of plastic or are they built of some other material that will actually last
Answer:	On my 2013 Jetta I had to turn the cables sideways on the post to get a better connection. If this does not work, it is because the battery is bad.

User questions & answers

Question:	Can these be wired in series, I know you can buy 12 volt but 6 volt wired in series work much better in RV's
Answer:	Wired in series gives you 12vdc. Wired in parallel gives you 6vdc with more current. My scissor lift uses 4, 6vdc batteries wired in series to get 24vdc at 200 amps.
Question:	hi will this battery fit a 1955 series 1 chev 6 cyl pick up
Answer:	I have the 6 volt version in my 1952 Chevrolet Hardtop. The battery will fit in the battery box at an angle. It is longer than the standard GM battery but much narrower, therefore you can angle it in the box and support the hold-down at the opposite corners and it will work fine. I had my Optima for 6 years in my Chevy.
Question:	Does the description's height of 7 13/16" (7.8") include the terminal posts? If not, what is the height of battery from base to top of posts
Answer:	Hi BrianI measured my battery roughly using a cheap tape but here goes. I measured the height of the plastic casing at approx. 7 1/4 by 10 inch long and 3 1/2 inch wide but from the bottom of the case to the top of the post is approx. 8 1/8 inches. Strange enough this battery would lie flat on it side in the battery tray with the posts towards the engine in my 40 Ford. I could stack two of them on their side if I had the right cable hook up. Nice battery, small for the standard tray but has decent power and holds its charge very well just sitting in garage 6 months. Hope this helped somewhat.Wayne
Question:	what is the warranty on the 6 v battery
Answer:	6V Passenger Vehicle / Light Truck (noncommercial) Optima 6 Volt battery warranty: 36 Months Free Replacement This from: https://www.speedwaymotors.com/Optima-Batteries-6V-1050-6-Volt-Battery,7163.html

Gentlemen, Start Your Engines

The RedTop high-performance AGM battery is the ultimate starting battery designed to deliver a powerful burst of ignition power for a reliable start-up every time. It will withstand hard launches, extreme corners and is race proven for every road every day whether it's used as a truck battery, automotive battery, or for other applications. Its reputation as a truck battery or automotive battery is unsurpassed.

SpiralCell Technology

At the heart of every OPTIMA battery is a series of individual spiral-wound cells comprised of two pure (99.99%) lead plates coated in a precise coating of lead oxide. One coated plate is positive and the other is negative.

The unique manufacturing process of spiral winding continuous lead plates is far more precision-controlled and expensive than building traditional flat plate AGM batteries. Custom automated cell-winding machines are required to maintain the close tolerances required to maintain quality and performance. Critical tolerances, temperatures, humidity and automated processes are maintained and constantly monitored.

OPTIMA has built over 100 million individual spiral cells since the early 1990’s.

RedTop

For normal engine starting where an alternator immediately monitors the state of charge and provides energy to the battery whenever it is needed.

This would describe most stock vehicles, including: automotive and RV underhood starting, heavy equipment where starting is the primary function, and diesel vehicles without aftermarket electronics.

YellowTop

Use this when electrical loads are higher than average, or when the discharge cycle is more than typical engine starting, such as vehicles with multiple electronic accessories and vehicles without alternators. This can also include vehicles with a lot of factory electronics such as power sliding doors and a DVD player. Examples also include: racing vehicles without a charging system, dedicated drag racers, diesel powered vehicles with aftermarket electronics, and vehicles with inverters, winches, or other accessories.

BlueTop

The BlueTop starting battery (dark gray case) is to be used when a dedicated starting battery is required and it should never be used for cycling duty. Use a BlueTop starting battery for marine applications and RVs when the battery's only function is engine starting.

The dual purpose BlueTop (light gray case) can be used for both starting and deep cycling -- it is a true deep cycle battery with extremely high cranking power. Uses include: trolling motors, marine applications with heavy electrical accessories, and RVs.

User questions & answers

Question:	which of these batteries would fit into a 1979 MG midget, 2 door convertible
Answer:	I believe all of them would fit into a 1979 MG Midget. They're not that small.....
Question:	This says unboxed. How is it packaged? Does it come with all the accessories in the retail box including spacing adapters
Answer:	Yes, mine came with the appropriate spacers for my particular form factor. I have a 2001 f-150 and I am sure glad it came with the spacers because I had to use one of them to get it to fit. I comes in a box with the spacer inside of it. So as far as the spacers go, Optima thought of everything! I am very pleased with the product!
Question:	does this battery come fully charged
Answer:	Mine came fully charged, my vehicle indicates 12.0V (engine not running) and ~13.8 to 14.0V (engine running). I keep this vehicle hooked up to a Deltran Battery Tender and it did not take too long for the Battery Tender to register Green (fully charged) once hooked up (~a few hours or so).
Question:	I see concerns about an Amazon warranty after 1 year yet the warranty noted in Amazon for the red top is clearly 36 months. What's the real deal
Answer:	It's 36 months through Optima. Unlike going back to the parts store what you have to do is file a claim with Amazon customer service. They do all the leg work from there. So here is the issue you have to decide if it's worth it or not. It can take a week between customer service contact, optima approves, new battery received. Can you make it a week without a battery??I have only seen one issue with an Optima battery back when I worked at a marine dealer. We sold a hundred or so a year (was there 2-1/2 years). Mine is only a couple months old, but I did accidentally kill it installing amps, subs, stereo, and it recharged and has no issues. Hope this helps.
