This battery only has a 1 year warranty, to which I am a bit nervous to buy this. Has anyone had this battery for 4+ years?

I've only had this battery in operation for 1 season. It's out of the car for the winter. Life has a lot to do with usage. I feel that the life will last for several seasons but obviously it will take several years to confirm.

My previous one (same model), lasted more than 10 years, and I did NOT take particularly good care of it. Here's an excerpt from my review:"2003 - early 2014: This Marathon 8AM-U1R lasted over 10 years and was still working when I replaced it (with the same model) in February 2014, mostly just for peace of mind!"

Mine failed after only 12 months. Couldn't get any shipper to accept the battery to return under warranty. Gave up and purchased an Optima locally.

Have one in my street Miata for well beyond 4 years, recently moved that battery to my Spec Miata and bought a new one for the street car when some other brand in the SM died. This is my 1st choice for the Miata.

I was going to buy this battery but decided against it because (a) there is no stated warranty and (b) no way to ask the vendor what their warranty is. This seems odd to me. When something seems odd like this, I stay away from the product and the vendor.

Contact the seller. I've had this battery for 2 or 3 years and have not had this issue.

I'm using it for about 3 years now and have no major problem. Probably the downside only the charging time longer and lifetime shorter than the original, but really worth your money for backup battery.

We went to our local Battery Plus store and they built us a better battery at about the same cost as the ones we found online. It was local and guaranteed for a year. It has been running for about two years with no problem and wife uses it almost everyday.

There is a sticker on the battery indicating the month and year of manufacture but you won't know until the battery is received. The four batteries I received were only 3 months old and the warranty does not begin until the date of sale. You'll have to contact the seller if you are really concerned.

Looking at another website, it looks like it comes with a "No Hassle" 2 year replace my warranty. Hope that helps. This battery rocks!

My battery has lasted a long time. Don't know exactly how long but a lot longer than 9 months. Maybe you just had a bad battery.

To begin with, this battery seems to have a history of problems. So far, my experience has been positive with no problems but I have only used it for 6 months. Checking water level would be my only recommendation.

My battery began losing charge after 9 mo. It is now exactly 1 year since I purchased it and it runs for 20 minutes. I did the reset thing but same result.

If I remember correctly, I had a 30 day replacement. I would have to go back through my purchase information. I can tell you as of now, I have had no problem what so ever with this replacement battery

My first battery lasted 3 years. I kept it in the basement during the winter and charged it every month. But when using it during the summer, I sometimes forgot to disconnect the charger the next day. This didn't happen a lot - maybe only 2 or 3 times a year. I didn't start to notice any problem until the end of the third year. I bought a new battery last spring. I've been more careful with this one and have always removed the charger within a few hours after the light turns green. This battery is still working very well, but it's too soon to know whether it will last more than 3 years.

That's a tough one to respond to. If it is a genuine Sony battery and there is no obvious damage, I would certainly try returning it. I don't know what the warranty is, but I would suspect it might be a year. Batteries are mass produced and like any mass produced item, you are bound to get a defect every now and then that makes it out of the factory. I've had no problem with mine, but yours is several months older.Good luck.

You would have to contact the seller for Warranty info. However...These batteries aren't guaranteed for 'long'. Our history has been they last about 3 years. I feel we get our monies worth.

I have not had any problems with my battery; it has worked great. Sorry you're having trouble.

Do you mean 10 years? My Mom had her original for years and I think she somehow wore it down early. But it was still years. This puppy is working great so far. And at this price the battery is essentially free. :-)She was having reception/dropped calls issues. Her house is on a mountain. She said she thinks the connection is getting sketchier because of the battery not holding as much of a charge. I said I don't think so. Well we got this replacement battery and the call reliability seems a lot better. Go figure.
