Just received Marathon "Miata Battery" Part No MAR-8AM-U1R. It says "Sealed, Valve Regulated Lead Acid Battery" is this an AGM Battery like original?

I am unwilling to break into the battery to verify, but Marathon says: "12 Volt 400 CCA Absorbed Glass Mat (AGM) Battery." Similarly, I wouldn't know if it is the same AGM as original.

Yes, but the 2 vents on the battery are in different places from OEM so you'll need to spend a buck for tubing to change is route.

The only decent battery you will find. Just have to clip your rubber tubes so they are ROUND and the battery works great. Be careful not to let the wrench hit the car body---when tighten the clamps. The exact "original" battery will not be found anywhere.

Yes, this is a very good battery, you have to use a little bit of creative mind to fit your vent hose to this battery.

I believe it is. But how can you tell? It doesn't slosh when shaked, so, again, I believe it is. Or simply, the solution is just gelled. Hope this helps.

I bought this battery and there isn't anything under the Ni-MH or any number/letter like that on it anywhere. Maybe it's just a manufacture date. I would chance-it because it's a great price!

Not sure as AGM is a brand I have tested deep cycle batteries with mine and had results as expected

I just received a reply from the manufacturer (EPSOLAR) and they state that AGM batteries can be used with the Tracer 2210RN controller with the battery selector set for "sealed battery". They do not recommend using the GEL setting and certainly not the FLOODED setting.

The battery in these packs are sealed lead acid AGM (absorbed glass mat). I've replaced the battery in another unit and it wasn't that hard. If you have the pack that looks exactly like the one in the picture here, it's battery is 3.875W X 5.875L X 3.75 H and is rated as 18 amp-hour. With that info you can go to dealers like "Battery plus" or "batteryspec.com" and match up another. When I changed out the battery in another unit, I added some padding as was on the original which cushion the battery keeping it from rubbing on the housing as it's carried or rattling slightly. The battery alone should only cost ~1/2 the price of a whole new pack, so it will save you some (but cost you the time to do it).

Hello, Yes, this battery is an AGM which has the electrolyte suspended in a fiberglass material between the internal plates. It is also maintenance free. Thank you for your interest. Battery Supersite

Good afternoon. in my case the battery is original, has very good durability load, I recommend it, is good.

It is a completely sealed maintenance free battery so you don't need it to be vented. It isn't like a standard lead acid battery which is why you need the vent. You will be fine to put this in.

Mine did that and it was the battery. They do have a shelf life. I replaced it, and it works great now. I got mine at BatteryMart.com and it is this one: 12 Volt 5 Ah F2 Terminal Sealed Lead Acid Battery Part# SLA-HR-1221W-F2. Hope that helps, good luck.

Hi Elizabeth. I'm using an Exide MC-31 MEGACYCLE AGM-200 (AGM) Marine Battery. Fully charged, this battery can keep the refer at 38 degrees for several days (depending on outside temp). I would not recommend running this off of a car battery/alternator.

IDK. It doesn't say, but it worked fine for the 10 days I used it. My stator was burnt up so I took this battery out and am still using the stock battery.

Amazon now says this: Warranty, Parts: Optima warrants to the original purchaser that this battery is free of defects in material and workmanship for a 36 month replacement period when shipped and sold by Amazon.com. If a replacement is necessary due to a defect in materials and/or workmanship the battery will be replaced free of charge, within the free replacement period from date of original purchase. Please contact Amazon Customer Service with your warranty claim. For purchases from Amazon Merchant sellers please contact the seller When I bought mine, This was not stated, that the warranty was through Optima. I called optima and they told me that they did not honor the Amazon Warranty, but did honor the Optima Warranty. However, since the battery was not sold through a qualified dealer, I would need to go to an Optima Distribution warehouse directly. There were 2 at the time, and one was near enough to me (2 hour drive) that I figured if the warranty was needed, I could drive there. That was Dec 2011 (2.5 years ago). I have had no issues at all with the battery though. Being sealed, there has been no terminal corrosion. The car starts well, even in 0 degree weather. Due to a broken foot, I have been out of the car for 4 weeks. I just went out to start it and the car started immediately. It is a great battery. I highly recommend it. All this being said, I recommend you ask Amazon directly what there policy is (they may be an authorized reseller now) and then contact Optima. This way you get the correct information directly from the parties who sell and make the battery.

I believe the replacement battery is an APC cartridge. It looked the same as the battery I replaced and the box says APC. However, since the battery is inside the APC unit, I can't verify the battery directly.

yeh propman...you read my review...watch out as you will not know untill sent....there isc a manufacture code on the batteryn that you can verify nwith optima...do not trust the date code (round) sticker as it is the ship date from the factory...not the manufacture date...fortunately...amazon backs their product and will and have replaced an old shipped optima...so buy with confidance...amazon has your back...just call them if older than 4 mo...you are correct...these need a full charge in a reasonable amount of time...they only come 40% from the factory...god luck and good fishin'
