Is this a new battery or a refurbished?

It's brand new and manufacturing date is always no more than 3 months from current date.

The one I ordered and received from MLC Distribution, Inc. was a genuine Sony battery, and the only steps involved were powering down the computer, removing the old one, popping the new one into place, and powering back up. It's the off-brand ones that require the BIOS patches, if I understand correctly. It seems as though some sellers are claiming to sell the genuine Sony product, but are shipping out third-party batteries of dubious quality. As I said, the one I ordered from MLC Distribution, Inc. was genuine and was identical to the battery my computer originally shipped with. However, check the back of the battery when it arrives. If you don't see it say SONY somewhere on it, I would advise sending it back and getting a full refund.

I think you should return the battery if it's not being detected by your laptop. Sorry for the late response. If you can't return it because it's so long since you purchased it try selling it.

Mine was not new, it is refurbished. But this was included in the item description. It did come in original box packed professionally and securely. It works great and its hard to believe its not brand new.

Both batteries were new as far as I could tell. Unit and batteries have been fine. I use mine once a week or more 7 months of the year at least.

The one I received IS a REFURBISHED unit. On the headband in the middle it's clearly printed "REFURB-W".

According to the description it is refurbished. I don' t know whether it is in the original box.

You didn't say what kind of 'new' battery. I learned long ago, get lithium batteries. Cost more, but less aggrevation. Also, perhaps if recently wet, there's moisture in battery area.

Two questions: is the charger functioning properly? And, is the battery old and no longer able to be charged?

The one I got was new. Should state if refurbished. Don't know about warranty.

Search the Internet using the battery number. Often times the old battery has been replaced with a new model with the same specs. Call vendor to make sure you are ordering the correct replacement.

It looks to me like a Dell Product. I've been using it in my laptop and I can't see any difference between the old and new battery.

The one I ordered was clearly marked as a refurb but looked and worked like new.

It came brand new to me. I've been using it for a while now. I didn't notice it to be refurbished.

The one i received was not in Lenovo packaging. The box was generic, as was the documentation. The battery itself had what appeared to be Lenovo markings, and LOOKED like it could be legit. After 1 cycle and a bios update, the battery stopped showing a charge (actually I think it stopped communicating with the computer)and was returned to the vendor. it was almost certainly a counterfeit item.I bought another battery from another site and it shipped in full Lenovo regalia, Printed box, printed security tape, hologram seals, full professional documentation etc. If your doesn't have these, it's probably not a real Lenovo item.

The one I ordered was a "refurbished" model about $40 cheaper. The second one I got works great.
